Aluminum Electrolytic Capacitor 

## Application  Guidelines 

## 1. Circuit Design 

Ensure that operational and mounting conditions follw the specified conditions detailed in the catalog and specification sheets. 

## 1.1 Operating Temperature and Frequency 

- Electrolytic capacitor electrical parameters are normally specified at 20°C temperature and 120Hz frequency. These parameters vary with changes in tempera t u r e  a n d  f requency. Circuit designers should take these changes into  consideration. 

- (1) Effects of operating temperature on electrical 

- parameters 

- a)At higher temperatures, leakage current and capacitance increase while equivalent series resistance(ESR) decreases. 

- b)At lower temperatures, leakage current and capacitance decrease while equivalent series resistance(ESR)  increases. 

- (2) Effects of frequency on electrical parameters 

- a ) A t  h i g h e r  f r e q u e n c i e s,  c a p a c i t a n c e  a n d impedance decrease while tan δ  increases. 

- b)At lower frequencies, ripple current generated heat will rise due to an increase in equivalent series resistance  (ESR). 

## 1.2 Operating Temperature and Life Expectancy 

- (1) Expected life is affected by operating temperature. 

- Generally, each 10°C reduction in temperature will double the expected life.  Use capacitors at the lowest p o s s i bl e  t e mperature below the maximum guaranteed temperature. 

- (2) If operating conditions exceed the maximum guaranteed limit, rapid eIectrical parameter deterioration will occur, and irreversible damage will result. 

- Check for maximum capacitor operating temperatures including ambient temperature,  internal capacitor temperature rise caused by ripple  current, and the effects of radiated heat from power transistors, IC?s or resistors. 

- Avoid placing components which could conduct heat to the capacitor from the back side of the circuit board. 

- (3)The formula for calculating expected Iife at lower operating temperatures is as fllows; 

**==> picture [101 x 14] intentionally omitted <==**

L1: Guaranteed life (h) at temperature, T1° C 

- L2: Expected life (h) at temperature,T2°C 

T1: Maximum operating temperature (°C) 

- T2: Actual operating temperature, ambient temperature + temperature rise due to ripple currentheating(°C) 

A quick eference capacitor guide for estimating exected life is included for your reference.

Aluminum Electrolytic Capacitor 

## 1.3 Common Application Conditions to Avoid 

The following misapplication load conditions will cause rapid deterioration to capacitor electrical parameters. ln addition, rapid heating and gas generation within the capacitor can occur causing the pressure relief vent to operate and resuItant leakage of electrolyte.  Under extreme conditions, explosion and fire could result. Leakinq electrolyte is combustible and electrically conductive. 

- (1) Reverse Voltaqe 

- DC capacitors have polarity. Verify correct polarity 

- before insertion.  For circuits with changing or uncertain polarity,use DC bipolar capacitors. DC bipolar capacitors are not suitable for use in AC circuits. 

## (2) Charqe/Discharqe Applications 

Standard capacitors are not suitable for use in repeating charge/discharge applications. For charqe/discharqe applications consult  us and advise actual conditions. 

## (3) Overvoltage 

- Do not  appIy voltaqes exceeding the maximum 

- specified rated voltages. Voltage up to the surge voltage rating are acceptable for short periods of time.  Ensure that the sum of the DC voltage and the superimposed AC ripple voltage does not exceed the rated voltage. 

## (4) Ripple Current 

Do not apply ripple currents exceeding the maximum specified value. For high ripple current applications, use a capacitor designed for high rippIe currents or contact us with your requirements. 

Ensure that allowable ripple currents superimposed on low DC bias voltages do not cause reverse voltage conditions. 

## 1.4 Using Two or More Capacitors in Series or Parallel 

- (1) Capacitors Connected in Parallel 

The circuit resistance can closely approximate the series resistance of the capacitor causing an imbalance of ripple current loads with in the capacitors. Careful design of wiring methods can minimize the possibility of excessive ripple currents applied to a capacitor. 

The vinyl sleeve of the capacitor can be damaged if solder passes through a lead hole for subsequently processed parts. Special care when locating hole positions in proximity to capacitors is recommended. 

## (3) Circuit Board Hole Spacing 

The circuit board holes spacing should match the capacitor lead wire spacing within the specified tolerances. Incorrect spacing can cause excessive lead wire stress during the insertion process. This may resuIt in premature capacitor failure due to short or open circuit, increased leakage current, or electrolyte leakage. 

## (4)Land/Pad Pattern 

The circuit board land/pad pattern size for chip capacitors is specified in the following table.

Among others, when the size a is wide , back fillet can not  be made,  decreasing fitting strength. 

D Decide considering mounting condition, solderability and fitting strength, etc. based on the design standards of your company. 

## (2) Capacitors Connected in Series 

Normal DC leakage current differences among capacitors can cause voltage imbalances. The use of voltage divider shunt resistors with consideration to leakage currents, can prevent capacitor voltage imbaIances. 

## 1.5 Capacitor Mounting Considerations 

## (1) DoubIe - Sided Circuit Boards 

Avoid wiring Pattern runs which pass between the mounted capacitor and the circuit board. When dipping into a solder bath, excess solder may collect under the capacitor by capillary action and shortcircuit the anode and cathode terminals. 

## (2) Circuit Board Hole Positioning 

Design, Specifications are subject to change without notice.  Ask factory for technical specifications before purchase and/or use. Whenever a doubt about safety arises from this product, please inform us immediately for technical consulation without fail.

- (5)Clearance for Case Mounted Pressure Relief Vents 

- Capacitors with case mounted pressure relief vents 

- require sufficient clearance to allow for proper vent operation. The minimum clearances are dependent 

- on capacitor diameters as follows. 

- f6.3 to f16 mm   : 2 mm minimum, 

- f18  to f35 mm   : 3 mm minimum. 

- f40 mm or greater: 5 mm minimum 

- (6)Clearance for Seal Mounted Pressure Relief Vents 

   - A hole in the circuit board directly under the seal vent location is required to allow proper release of pressure. 

- (7)Wiring Near the Pressure Relief Vent Avoid locating high voltage or high current wiring or circuit board paths above the pressure relief vent. Flammable, high temperature gas exceeding 100°C may be released which could dissolve the wire insulation and ignite. 

- (8)Circuit Board Patterns Under the Capacitor Avoid circuit board runs under the capacitor as electrolyte leakage could cause an electrical short. 

- (9)Screw Terminal Capacitor Mounting 

- G Do not orient the capacitor with the screw terminal side of the capacitor facing downwards. 

- G Tighten the terminal and mounting bracket screws w i t h i n  t h e  t o r q u e  r a n g e  s p e c i f i e d  i n  t h e specification. 

## 1.6Electrical Isolation of the Capacitor 

- Completely isolate the capacitor as follows. 

- 2.Capacitor Handling Techniques 

- 2.1 Considerations Before Using 

- (1) Capacitors have a finite life. Do not reuse or recycle capacitors from used equipment. 

- (2) Transient recovery voltage may be generated in the capacitor due to dielectric absorption. If required, this voltage can be discharged with a resistor with a value of about 1 kΩ. 

- (3) Capacitors stored for long periods of time may exhibit an increase in leakage current. This can be corrected by gradually applying rated voltage in series with a resistor of approximately 1 kΩ. 

- (4) If capacitors are dropped, they can be damaged mechanically or electrically. Avoid using dropped capacitors. 

- (5) Dented or crushed capacitors should not be used. The seal integrity can be compromised and loss of electrolyte/shortened life can result. 

## 2.2 Capacitor Insertion 

   - (1) Verify the correct capacitance and rated voltage of the capacitor. 

   - (2) Verify the correct polarity of the capacitor before inserting. 

   - (3) Verify the correct hole spacing before insertion (land pattern size on chip type) to avoid stress on the terminals. 

   - (4) Ensure that the auto insertion equipment lead clinching operation does not stress the capacitor leads where they enter the seal of the capacitor. For chip type capacitors, excessive mounting pressure can cause high leakage current, short circuit, or disconnection. 

- G  Between the cathode and the case (except for 

- axially leaded B types) and between the anode terminal and other circuit paths. 

- G Between the extra mounting terminals (on T types) and the anode terminal, cathode terminal, and other circuit paths. 

## 1.7Capacitor Sleeve 

The vinyl sleeve or laminate coating is intended for marking and identification purposes and is not meant to electrically insulate the capacitor. 

The sleeving may split or crack if immersed into solvents such as toluene or xylene, and then exposed to high temperatures. 

## 2.3 Manual Soldering 

- (1) Observe temperature and time soldering specifications or do not exceed temperatures of 350°C for 3 seconds or less. 

- (2) If lead wires must be formed to meet terminal board hole spacing, avoid stress on the leadwire where it enters the capacitor seal. 

- (3) If a soldered capacitor must be removed and reinserted, avoid excessive stress to the capacitor leads. 

- (4) Aviod touching the tip of the soldering iron to the capacitor, to prevent melting of the vinyl sleeve. 

Always consider safety when designing equipment and circuits. Plan for worst case failure modes such as short circuits and open circuits which could occur during use. 

- (1)Provide protection circuits and protection devices to allow safe failure modes. 

- (2)Design redundant or secondary circuits where possible to assure continued operation in case of main circuit failure. 

Design, Specifications are subject to change without notice.  Ask factory for technical specifications before purchase and/or use. Whenever a doubt about safety arises from this product, please inform us immediately for technical consulation without fail.

## 2.4 Flow Soldering 

## 2.6Other Soldering Considerations 

- (1) Don not immerse the capacitor body into the solder bath as excessive internal pressure could result. 

   - Rapid temperature rises during the preheat operation and resin bonding operation can cause cracking of the capacitor vinyl sleeve. For heat curing, do not exceed 150°C for a maximum time of 2 minutes. 

- (2) Observe proper soldering conditions (temperature, time, etc.). Do not exceed the specified limits. 

- (3) Do not allow other parts or components to touch the capacitor during soldering. 

   - 2.7 Capacitor Handling after Soldering 

- 2.5 Reflow Soldering for Chip Capacitors 

- (1) For reflow, use a thermal conduction system such as infrared radiation (IR) or hot blast. Vapor heat transfer systems (VPS) are not recommended. 

   - (1) Avoid movement of the capacitor after soldering to prevent excessive stress on the leadwires where they enter the seal. 

- (2) Observe proper soldering conditions (temperature, time, etc.). Do not exceed the specified limits. 

   - (2) Do not use the capacitor as a handle when moving the circuit board assembly. 

- (3) Reflow should be performed one time. Consult us for additional reflow restrictions. 

- (3) Avoid striking the capacitor after assembly to prevent failure due to excessive shock.

## 2.9 Mounting Adhesives and Coating Agents 

When using mounting adhesives or coating agents to control humidity, avoid using materials containing halogenated solvents. Also, avoid the use of chloroprene based polymers. 

- 8 After applying adhesives or coatings, dry thoroughly to prevent residual solvents from being trapped between the capacitor and the circuit board. 

## 3.Precautions for using capacitors 

## 3.1Environmental Conditions 

Capacitors should not be used in the following environments. 

- (1) Temperature exposure above the maximum rated or below the minimum rated temperature of the capacitor. 

- (2) Direct contact with water, salt water, or oil. 

- (3) High humidity conditions where water could condense on the capacitor. 

## 3.2 Electrical Precautions 

- (1) Avoid touching the terminals of the capacitor as possible electric shock could result. The exposed aluminium case is not insulated and could also cause electric shock if touched. 

- (2)Avoid short circuiting the area between the capacitor terminals with conductive materials including liquids such as acids or alkaline solutions. 

## 4.Emergency Procedures 

- (1) If the pressure relief vent of the capacitor operates, immediately turn off the equipment and disconnect from the power source. This will minimize additional damage caused by the vaporizing electrolyte. 

- (2) Avoid contact with the escaping electrolyte gas which can exceed 100°C temperatures. If electrolyte or gas enters the eye, immediately flush the eye with large amounts of water. If electrolyte or gas is ingested by mouth, gargle with water. If electrolyte contacts the skin, wash with soap and water. 

## 5. Long Term Storage 

Leakage current of a capacitor increases with long storage times. The aluminium oxide film deteriorates as a function of temperature and time. If used without reconditioning, an abnormally high current will be required to restore the oxide film. This current surge could cause the circuit or the capacitor to fail. Capacitor should be reconditioned by applying rated voltage in series with a 1000 Ω, current limiting resistor for a time period of 30 minutes. 

## 5.1 Environmental Conditions (Storage) 

Capacitors should not be stored in the following environments. 

   - (1) Temperature exposure above 35°C or below 15 °C. 

   - (2) Direct contact with water, salt water, or oil. 

   - (3) High humidity conditions where water could condense on the capacitor. 

   - (4) Exposure to toxic gases such as hydrogen sulfide,sulfuric acid, nitric acid, chlorine, or ammonia. 

   - (5) Exposure to ozone, radiation, or ultraviolet rays. 

   - (6) Vibration and shock conditions exceeding specified requirements. 

- (4) Exposure to toxic gases such as hydrogen sulfide, sulfuric acid, nitric acid, chlorine, or ammonia. 

- (5) Exposure to ozone, radiation, or ultraviolet rays. 

- (6) Vibration and shock conditions  exceeding specified requirements.

## 6.Capacitor Disposal 

When disposing of capacitors, use one of the following methods. 

- G Incinerate after crushing the capacitor or puncturing the can wall (to prevent explosion due to internal pressure rise). Capacitors should be incinerated at high temperatures to prevent the 

- release of toxic gases such as chlorine from the polyvinyl chloride sleeve, etc. 

- G Dispose of as solid waste. 

- G L o c a l  l a w s  m a y  h a v e  s p e c i f i c  d i s p o s a l requirements which must be followed.
