82µF - 400V

Description

This 82 µF / 400 V electrolytic capacitor is a high-voltage radial lead aluminum electrolytic from the ERA series. It is engineered as a general-purpose, high-reliability smoothing and energy-storage component for power electronics where compact size and high working voltage are required. The part is built to withstand elevated ambient temperatures and is intended for long duty in demanding circuits. Constructed with electrolyte-impregnated aluminum foil and a robust sealing system, the capacitor balances volumetric efficiency with thermal endurance. In normal operation it provides bulk capacitance for DC link stabilization, ripple suppression and transient energy buffering. Its mechanical footprint and leaded terminations make it straightforward to mount into through-hole PCBs or point-to-point assemblies. The ERA series specification calls out high endurance at 105 °C and standardized tolerances and dissipation parameters, so the 82 µF/400 V variant offers predictable ageing and leakage behaviour over long service intervals. Its combination of relatively high ripple capability in a small cylinder (18×26 mm) makes it suitable where high voltage and modest capacitance are needed without a large board area.
