Box 5928 • Greenville, SC 29606 (864) 963-6300 • www.kemet.com A4009_ESW • 1/6/2016 Single-Ended Aluminum Electrolytic Capacitors – ESW Series, +105ºC Mounting Positions (Safety Vent) In operation, electrolytic capacitors will always conduct a leakage current which causes electrolysis. 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 that the connections of the capacitors are able to insert on the board without excessive mechanical force. • 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. • Verify that the space around the pressure relief device is according to the following guideline: Case Diameter Space Around Safety Vent ≤16mm > 2 mm >16to≤40mm > 3 mm > 40 mm > 5 mm It is recommended that capacitors always be mounted with the safety device uppermost or in the upper part of the capacitor. • Ifthecapacitorsarestoredforalongtime,theleakagecurrentmustbeverified.Iftheleakagecurrentissuperiortothevaluelistedin this catalog, the capacitors must be reformed. In this case, they can be reformed by application of the rated voltage through a series resistorapproximately1kΩforcapacitorswithV R≤160V(5Wresistor)and10kΩfortheotherratedvoltages. • 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. |
