CAPACITOR, FIXED, ELECTROLYTIC (DC, ALUMINUM, DRY ELECTROLYTE, POLARIZED), GENERAL SPECIFICATION FOR
|Publication Date:||18 August 2020|
This specification covers the general requirements for polarized, dry-electrolyte, aluminum, direct current (dc), fixed capacitors for use in filter and bypass circuits where large excesses of capacitance over the nominal capacitance can be tolerated.

Aluminum oxide electrolytic capacitors are intended for use in filter and bypass applications where large capacitance values are required in small cases and where excess of capacitance over the nominal value can be tolerated. For polarized capacitors, the applied ac peak voltage should never exceed the applied dc voltage; the sum of the applied ac peak and dc voltages should never exceed the dc rated voltage (see 3.1). They are military unique due to the fact that they must be able to operate satisfactorily in military systems under the following demanding conditions: +85°C operating temperature range, 100Gs of shock, 48 hours of salt spray corrosion, and 2000 hours of rated voltage testing. Commercial components are not designed to withstand these military environmental conditions.View Less
