## **Environmental Compliance** 

**==> picture [220 x 71] intentionally omitted <==**

All Part Numbers in this datasheet are Reach and RoHS compliant, and Halogen-Free. 

As an environmentally conscious company, KEMET is working continuously with improvements concerning the environmental effects of both our capacitors and their production. In Europe (RoHS Directive) and in some other geographical areas like China, legislation has been put in place to prevent the use of some hazardous materials, such as lead (Pb), in electronic equipment. All products in this catalog are produced to help our customers' obligations to guarantee their products and fulfill these legislative requirements. The only material of concern in our products has been lead (Pb), which has been removed from all designs to fulfill the requirement of containing less than 0.1% of lead in any homogeneous material. KEMET will closely follow any changes in legislation worldwide and make any necessary changes in its products, whenever needed. 

Some customer segments such as medical, military and automotive electronics may still require the use of lead in electrode coatings. To clarify the situation and distinguish products from each other, a special symbol is used on the packaging labels for RoHS compatible capacitors. 

Due to customer requirements, there may appear additional markings such as lead-free (LF) or lead-free wires (LFW) on the label.

## **Shelf Life & Re-Ageing** 

## **Shelf Life** 

Solderability is 12 months after manufacturing date. 

The capacitance, ESR and impedance of a capacitor will not change significantly after extended storage periods, however the leakage current will slowly increase. 

- This series should not be stored in high temperatures or where there is a high level of humidity. 

- The suitable storage condition is +5 to +35°C and less than 75% in relative humidity. 

- Do not store in damp conditions such as water, saltwater spray or oil spray. 

- Do not store in an environment of hazardous gas (hydrogen sulphide, sulphurous acid gas, nitrous acid, chlorine gas, ammonium, etc.) 

- •Do not store under exposure to ozone, ultraviolet rays or radiation. 

## **If a capacitor has been stored for more than 12 months under these conditions and it shows increased leakage current, then a treatment by voltage application is recommended.** 

Note: The JEDEC-J-STD-020 standard does not apply. 

## **Floor Life** 

The Capacitor should be soldered within 4 weeks after removal from sealed bag. Reseal the unused capacitors into plastic bags. All parts manufactured from week 1 of year 2022 are packed in sealed plastic bags. 

## **Re-age Procedure** 

Apply the rated DC voltage to the capacitor at 105°C for a period of 120 minutes through a 1 kΩ series resistor.

Surface Mount Solid Polymer Aluminum Capacitors A767 105°C 

## **Installing** 

Solid Polymer Aluminum Capacitors are prone to a change in leakage current due to thermal stress during soldering. The leakage current may increase after soldering or reflow soldering. Therefore, verify the suitability for use in circuits sensitive to leakage current. 

A general principle is that lower temperature operation results in a longer, useful life of the capacitor. For this reason, it should be ensured that electrolytic capacitors are placed away from heat-emitting components. Adequate space should be allowed between components for cooling air to circulate, especially when high ripple current loads are applied. In any case, the maximum rated temperature must not be exceeded. 

- Do not deform the case of capacitors or use capacitors with a deformed case. 

- Verify that the connections of the capacitors are able to insert on the board without excessive mechanical force. Excessive force during insertion, as well as after soldering may cause terminal damage and affect the electrical performance. 

- Ensure electrical insulation between the capacitor case, negative terminal, positive terminal and PCB. 

- If the capacitors require mounting through additional means, the recommended mounting accessories shall be used. 

- Verify the correct polarization of the capacitor on the board. 

KEMET recommends, to ensure that the voltage across each capacitor does not exceed its rated voltage. 

## **Temperature Stability Characteristics** 

table characteristics in a very low temperature range allows for less circuits in the design. 

Due to a solid polymer electrolyte, Solid Polymer Aluminum Capacitors feature higher conductivity. This results in a lower ESR which, coupled with high capacitance allows an aluminum polymer capacitor to replace several standard electrolytic capacitors, reducing the number of components and maximizing board space. 

The ESR of polymer capacitors is nearly constant within its operating temperature range, while the ESR of a standard electrolytic capacitor noticeably changes with temperature.

## **Expected Life Calculation Chart** 

Expected life depends on operating temperature according to the following formula: L = Lo x 10[(To-T)/20] 

Where: 

- L:    Expected life 

- Lo:  Life at maximum permissible operating temperature with rated operating voltage applied (hours) 

- T:    Actual operating temperature 

- To:  Maximum permissible operating temperature

The effect of derating temperature can be seen in this graph. 

In this example, the life expectancy of a 2,000 hour polymer capacitor is significantly greater than that of a 2,000 hour standard electrolytic capacitor.

Surface Mount Solid Polymer Aluminum Capacitors A767 105°C 

## **Construction Data** 

The manufacturing process begins with the anode foil being electrochemically etched to increase the surface area and then ‘formed’ to produce the aluminum oxide layer. Both the anode and cathode foils are then interleaved with absorbent paper and wound into a cylinder. During the winding process, aluminum tabs are attached to each foil to provide the electrical contact. 

The deck, complete with terminals, is attached to the tabs and then folded down to rest on top of the winding. The complete winding is impregnated with a conductive polymer electrolyte before being housed in a suitable container, usually an aluminum can, and sealed. Throughout the process, all materials inside the housing must be maintained at the highest purity and be compatible with the electrolyte. 

Each capacitor is aged and tested before being packed. The purpose of aging is to repair any damage in the oxide layer and thus reduce the leakage current to a very low level. Aging is normally carried out at the rated temperature of the capacitor and is accomplished by applying voltage to the device while carefully controlling the supply current. The process may take several hours to complete. Damage to the oxide layer can occur due to a variety of reasons:

## **Product Safety** 

_THESE NOTES SHOULD BE READ IN CONJUNCTION WITH THE PRODUCT DATA SHEET. FAILURE TO OBSERVE THE RATINGS AND THE INFORMATION ON THIS SHEET MAY RESULT IN A SAFETY HAZARD._ 

## **Warning** 

**When potential lethal voltages e.g., 30 VAC (RMS) or 60 VDC are applied to the terminals of this product, the use of a hazard warning label is recommended.** 

## 1. Electrolyte 

Conductive polymer aluminum solid electrolytic capacitors contain polymers (electrolytes) which can be hazardous. 

## 1.1 Safety Precautions 

In the event of gas venting, avoid contact and inhalation. Wash the affected area with hot water. Use rubber gloves to avoid skin contact. Any contact with the eyes should be liberally irrigated with water and medical advice sought. 

## 2. Intrinsic Properties 

## 2.1 Operating 

DC capacitors are polar devices and will operate safely only if correctly connected. Reversing the connections will result in high leakage currents which could subsequently cause short circuit failure and possibly explosion and fire. Correctly polarized operation may result in the above failure modes if: 

- The surge voltage is exceeded 

- The ambient temperature is too high 

- Excessive ripple currents are applied 

## 2.2 Non-Operating 

Excessive torque or soldering heat may affect the performance of the capacitor or damage the sealing. Electric shock may result if capacitors are not discharged. 

## 3. Disposal 

Aluminum electrolytic capacitors are consignable waste under the Special Waste Regulations 1996 (Statutory Instrument 1996 No 972), which complies with the EC Hazardous Waste Directive – Directive 91/689/EEC. The electrolyte should therefore be treated as a hazardous waste and advice should be sought from the local office of the environmental agency regarding its disposal. 

Due to the construction of an aluminum electrolytic capacitors, high temperature incineration may cause the component to explode due to build-up of internal pressure. In addition, incineration may also cause the emission of noxious fumes. KEMET strongly recommends that if there are any doubts regarding the disposal of conductive polymer aluminum solid electrolytic capacitors, that advice be sought from the local regulating authority. 

In addition, KEMET would like to request that users of aluminum electrolytic capacitors respect the needs of the environment and, wherever possible, recover as much of the materials as possible, i.e. aluminum.

## **Product Safety cont.** 

## 4. Unsafe Use 

Most failures are of a passive nature and do not represent a safety hazard. A hazard may, however, arise if this failure causes a dangerous malfunction of the equipment in which the capacitor is employed. Circuits should be designed to fail safe under the normal modes of failure. 

The usual failure mode is an increase in leakage current or short circuit. Other possible modes are a decrease of capacitance, an increase in dissipation factor (and impedance) or an open circuit. Capacitors should be used in a wellventilated enclosure or cabinet. 

## 5. Mounting 

Care should be taken when mounting by a clamp, that any safety vent in the can is not covered. 

## 6. Fumigation 

In many countries throughout the world it is now common practice to fumigate shipments of products in order to control insect infestation, particularly when wooden packaging is used. Currently, methyl bromide, is widely used as a fumigant, which can penetrate cardboard packing and polymer bags and, therefore, come into direct contact with equipment or components contained within. 

If aluminum electrolytic capacitors become exposed to methyl bromide then corrosion may occur, depending upon the concentration and exposure time to the chemical. 

This failure mode can affect all types of KEMET aluminum electrolytic capacitors. Methyl bromide can penetrate the seals of aluminum electrolytic capacitors and cause internal corrosion of the anode connection, resulting in the component becoming open circuit. The rate of corrosion will depend upon the level of exposure to methyl bromide, as well as the subsequent operating conditions, such as voltage and temperature. It may take months or, in some cases, several years before the component becomes open circuit. 

## 7. Dielectric Absorption 

A phenomenon known as dielectric absorption can cause aluminum electrolytic capacitors to recharge themselves. The phenomenon is well known but impossible to predict with any great accuracy, so potentially any electrolytic product could be affected. Thus, a capacitor that has been charged and then completely discharged will appear to recharge itself if left open circuit; this will manifest itself as a small voltage across the terminals of the capacitor. Generally, the voltages seen are less than 20 VDC. However, higher voltages have on occasion been reported. 

In order to avoid any problems caused by this voltage, KEMET recommends that capacitors be discharged before connecting to the terminals.
