**Shelf Life** The capacitance, ESR, and impedance of a capacitor will not change significantly after extended storage periods; however, the leakage current will very slowly increase. KEMET products are particularly stable and allow a shelf life in excess of three years at 40°C. See sectional specification under each product series for specific data. ## **Re-age (Reforming) Procedure** Apply the rated voltage to the capacitor at room temperature for a period of one hour or until the leakage current has fallen to a steady value below the specified limit. During re-aging, a maximum charging current of twice the specified leakage current or 5 mA (whichever is greater) is suggested. ## **Reliability** The reliability of a component can be defined as the probability that it will perform satisfactorily under a given set of conditions for a given length of time. In practice, it is impossible to predict with absolute certainty how any individual component will perform. Therefore, we must utilize probability theory. It is also necessary to clearly define the level of stress involved (e.g., operating voltage, ripple current, temperature, and time.) Finally, the meaning of satisfactory performance must be defined by specifying a set of conditions, which determine the end of life of the component. KEMET provides an online life calculator that can be used to predict hours of life for a given part number in specific application conditions.

**Environmental Compliance** **==> picture [220 x 76] 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 such as 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. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com A4081_ALC70 • 9/16/2020 12 Snap-In Aluminum Electrolytic Capacitors – ALC70, +85°C ## **Mechanical Data** ## **Polarity and Reversed Voltage** Aluminium Electrolytic capacitors manufactured for use in DC applications contain an anode foil and a cathode foil. As such, they are polarized devices and must be connected with the +ve to the anode foil and the -ve to the cathode foil. If this were to be reversed then the electrolytic process that took place in forming the oxide layer on the anode would be recreated in trying to form an oxide layer on the cathode. In forming the cathode foil in this way, heat would be generated and gas given off within the capacitor, usually leading to catastrophic failure. The cathode foil already possesses a thin stabilized oxide layer. This thin oxide layer is equivalent to a forming voltage of approximately 2 V. As a result, the capacitor can withstand a voltage reversal of up to 2 V for short periods. Above this voltage, the formation process will commence. Aluminium Electrolytic capacitors can also be manufactured for use in intermittent AC applications by using two anode foils in place of one anode and one cathode. ## **Mounting Position** The capacitor can be mounted upright or inclined to a horizontal position. Special attention for the safety vent coverage, which this ensures that internal gas generated can escape when the pressure reaches a certain value due to overstress or catastrophic failure. All mounting positions must allow the safety vent to work properly. ## **Insulating Resistance** ≥ 100 MΩ at 100 VDC across insulating sleeve. ## **Voltage Proof** ≥ 3,500 VDC across insulating sleeve. ≥ 2,500 VAC across insulating sleeve. ## **Safety Vent** For diameters up to 40 mm, the safety vent for overpressure is featured on the base (opposing end to the terminals), and for diameters 45 mm or higher, the safety vent is featured in the side of the can. This is a weakened area in the bottom of the can that is designed to relieve build-up of internal pressure due to overstress or catastrophic failure. © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com A4081_ALC70 • 9/16/2020 13 Snap-In Aluminum Electrolytic Capacitors – ALC70, +85°C ## **Marking** **==> picture [295 x 124] intentionally omitted <==** **----- Start of picture text -----**<br> KEMET Logo<br>Polarity Stripe (−)<br>Rated Capacitance,<br>Capacitance Tolerance<br>Rated Voltage (VDC)<br>Series, Capacitance<br>Code, Voltage Code<br>Climatic Category<br>Date of Manufacture,<br>Batch Number<br>Made in the<br>European Union<br>**----- End of picture text -----**<br> _*Print shown is representative of the data included on the sleeve.

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 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 sleeved and 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 variety of reasons: - Slitting of the anode foil after forming - Attaching the tabs to the anode foil - Minor mechanical damage caused during winding A sample from each batch is taken by the quality department after completion of the production process. This sample size is controlled by the use of recognized sampling tables defi ned in BS 6001. The following tests are applied and may be varied at the request of the customer. In this case the batch, or special procedure, will determine the course of action. ## Electrical: Mechanical/Visual: - Leakage current - Overall dimensions - Torque test of mounting stud - Capacitance - Print detail - ESR - Impedance - Box labels - Tan Delta - Packaging, including packed quantity **==> picture [253 x 179] intentionally omitted <==** **----- Start of picture text -----**<br> Extended cathode<br>Anode foil<br>Foil tabs<br>Tissues<br>Cathode foil<br>**----- End of picture text -----**<br> **==> picture [204 x 374] intentionally omitted <==** **----- Start of picture text -----**<br> Etching<br>Forming<br>Winding<br>Decking<br>Impregnation<br>Assembly<br>Aging<br>Testing<br>Sleeving<br>Packing<br>**----- End of picture text -----**<br> © KEMET Electronics Corporation • KEMET Tower • One East Broward Boulevard Fort Lauderdale, FL 33301 USA • 954-766-2800 • www.kemet.com A4081_ALC70 • 9/16/2020 15 Snap-In Aluminum Electrolytic Capacitors – ALC70, +85°C ## For a complete list of our global sales offi ces, please visit www.kemet.com/sales. ## **Disclaimer** All product specifi cations, statements, information and data (collectively, the “Information”) in this datasheet are subject to change.
