Applications
ECA1VHG332 is widely used as a bulk filter capacitor in switch-mode power supply output stages, where 3300 µF at 35 V provides energy storage to smooth rectified AC waveforms and suppress output ripple voltage below 50 mV. Its large capacitance makes it effective for hold-up circuits in industrial power supplies and UPS systems that must maintain voltage during brief input interruptions of several milliseconds. The radial leaded 16 mm body also fits standard PCB mounting holes in motor drive filter stages and audio amplifier power rails requiring low-impedance bulk capacitance.

Frequently Asked Questions
What is the capacitance and voltage rating of ECA1VHG332 and what ripple filtering does it provide?
ECA1VHG332 is a 3300 µF aluminum electrolytic capacitor rated at 35 V. At this capacitance, it effectively filters low-frequency ripple currents at 100 Hz or 120 Hz in rectified power supplies, reducing output ripple voltage significantly in bulk filter stages where the charge stored in 3300 µF limits voltage droop between rectifier pulses.
How does ECA1VHG332 perform in a hold-up circuit powering a 24 V industrial controller during brief input dropout?
ECA1VHG332 stores approximately 185 mJ of energy at 35 V full charge (E = 0.5 x 3300 µF x 35² V). If the supply input drops briefly and the output discharges from 35 V to 24 V, this 3300 µF capacitor can supply a 500 mA load for approximately 73 ms, providing enough hold-up time for an orderly shutdown sequence in industrial controllers.
What PCB mounting requirements does ECA1VHG332 have given its 16 mm diameter body?
ECA1VHG332 has a 16 mm diameter body with radial leads spaced at a standard 7.5 mm pitch, requiring two through-hole PCB pads at 7.5 mm center-to-center distance. The component height is typically 25 mm to 35 mm depending on the specific series variant, and designers should verify clearance above the board for adjacent components and enclosure lids.
Is ECA1VHG332 suitable for audio amplifier power supply filtering and what leakage current should designers expect?
Yes, ECA1VHG332 is used in audio power amplifier rails where high bulk capacitance of 3300 µF at 35 V reduces power supply impedance at low frequencies below 100 Hz, minimizing hum pickup in the amplifier output. Its maximum leakage current of 1.155 mA is acceptable for most audio supply rails rated at 30 V to 35 V, though designers should account for the cumulative leakage when multiple capacitors are paralleled.
