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 world wide and makes 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. Because of customer requirements, there may appear additional markings such as LF = Lead Free or LFW = Lead Free Wires on the label. **==> picture [67 x 50] intentionally omitted <==** © KEMET Electronics Corporation • P.O.

The oxygen produced by electrolysis will regenerate the dielectric layer but, at the same time, the hydrogen released may cause the internal pressure of the capacitor to increase. The overpressure vent (safety vent) ensures that the gas can escape when the pressure reaches a certain value. All mounting positions must allow the safety vent to work properly. ## **Installing** - A general principle is that lower-use temperatures result 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, particularly when high ripple current loads are applied. In any case, the maximum category temperature must not be exceeded. - Do not deform the case of capacitors or use capacitors with a deformed case. - Verify the correct polarization of the capacitor on the board. It is recommended that capacitors always be mounted with the safety device uppermost or in the upper part of the capacitor. - If the capacitors are stored for a long time, the leakage current must be verified. If the leakage current is superior to the value listed in this catalog, the capacitors must be reformed. In this case, they can be reformed by application of the rated voltage through a series resistor approximately 1 kΩ for capacitors with VR ≤ 160 V (5 W resistor) and 10 kΩ for the other rated voltages. - In the case of capacitors connected in series, a suitable voltage sharing must be used. In the case of balancing resistors, the approximate resistance value can be calculated as: R = 60/C KEMET recommends, nevertheless, to ensure that the voltage across each capacitor does not exceed its rated voltage. ## **Application and Operation Guidelines** ## **Electrical Ratings: Capacitance (ESC)** Capacitance is measured by applying an alternate voltage of ≤ 0.5 V at a frequency of 120 or 100 Hz and 20°C. ## **Temperature Dependence of the Capacitance** Capacitance of an electrolytic capacitor depends upon temperature: with decreasing temperature the viscosity of the electrolyte increases, thereby reducing its conductivity. Capacitance will decrease if temperature decreases. Furthermore, temperature drifts cause armature dilatation and, therefore, capacitance changes (up to 20% depending on the series considered, from 0 to 80°C). This phenomenon is more evident for electrolytic capacitors than for other types. © KEMET Electronics Corporation • P.O.

Re is the most temperature-dependent component of an electrolytic capacitor equivalent circuit. Electrolyte resistivity will decrease if temperature rises. In order to obtain a low impedance value throughout the temperature range, Re must be as little as possible. However, Re values that are too low indicate a very aggressive electrolyte, resulting in a shorter life of the electrolytic capacitor at high temperatures. A compromise must be reached. ## **Leakage Current (LC)** Due to the aluminum oxide layer that serves as a dielectric, a small current will continue to flow even after a DC voltage has been applied for long periods. This current is called leakage current. A high leakage current flows after applying voltage to the capacitor then decreases in a few minutes, e.g., after prolonged storage without any applied voltage. In the course of continuous operation, the leakage current will decrease and reach an almost constant value. After a voltage-free storage the oxide layer may deteriorate, especially at high temperature. Since there are no leakage currents to transport oxygen ions to the anode, the oxide layer is not regenerated. The result is that a higher than normal leakage current will flow when voltage is applied after prolonged storage. As the oxide layer is regenerated in use, the leakage current will gradually decrease to its normal level. © KEMET Electronics Corporation • P.O.

## Where: ## VF = **Forming voltage** If this level is exceeded, a large quantity of heat and gas will be generated and the capacitor could be damaged. ## VR = **Rated voltage** This level represents the top of the linear part of the curve. ## VS = **Surge voltage** This lies between VR and VF. The capacitor can be subjected to VS for short periods only. Electrolytic capacitors are subjected to a reforming process before acceptance testing. The purpose of this preconditioning is to ensure that the same initial conditions are maintained when comparing different products. ## **Ripple Current (RC)** The maximum ripple current value depends on: - Ambient temperature - Surface area of the capacitor (heat dissipation area) tan δ or ESR - Frequency The capacitor’s life depends on the thermal stress. ## **Frequency Dependence of the Ripple Current** ESR and, thus, the tan δ depend on the frequency of the applied voltage. This indicates that the allowed ripple current is also a function of the frequency. ## **Temperature Dependence of the Ripple Current** The data sheet specifies maximum ripple current at the upper category temperature for each capacitor. © KEMET Electronics Corporation • P.O.

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. 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. ## Mechanical/Visual: Electrical: - Overall dimensions - Leakage current - Capacitance - Torque test of mounting stud - ESR - Print detail - Impedance - Box labels - Tan Delta - Packaging, including packed quantity **==> picture [253 x 179] intentionally omitted <==** **----- Start of picture text -----**
