Key Features
- 3300 µF high-capacitance aluminum electrolytic in a radial 16 mm body for robust bulk energy storage in power supplies
- Low leakage current of 1.155 mA ensures minimal standby drain in audio amplifiers and motor drive filter stages
- RoHS-compliant (JESD-609 e3) wet aluminum construction for long operational lifetime in industrial and consumer designs
Applications
The ECA1VM332 serves as a bulk energy-storage and smoothing capacitor on the DC bus of AC-DC power supplies, motor drives, and class-D audio amplifiers where 3300 µF at the rated voltage reduces output ripple. Its 16 mm radial leaded form factor mounts directly in through-hole positions on main power boards and UPS circuits. The wet aluminum construction supports long service life in HVAC controllers, industrial inverters, and professional audio equipment.

Frequently Asked Questions
What capacitance and leakage current does the Panasonic ECA1VM332 offer for power supply designs?
The ECA1VM332 provides 3300 µF of capacitance with a leakage current of only 1.155 mA. This large capacitance is ideal for smoothing rectified mains voltages in AC-DC converters, reducing output ripple to acceptable levels for sensitive loads such as microcontrollers and audio amplifiers operating from a regulated DC rail.
Which bulk filtering or energy-storage circuits benefit from using the ECA1VM332 with its 16 mm radial body?
AC-DC power supply filter stages, class-D amplifier power rails, and motor drive DC bus capacitor banks all benefit from the 3300 µF stored energy in the ECA1VM332. The 16 mm diameter radial leaded package fits standard through-hole PCB footprints and provides the physical clearance needed for large-capacitance applications in UPS systems, industrial inverters, and HVAC motor controllers.
When should a designer choose the ECA1VM332 over multiple small SMD capacitors for the same total capacitance?
A single ECA1VM332 at 3300 µF occupies far fewer board-assembly steps than paralleling dozens of SMD electrolytics to reach the same capacitance. The radial through-hole construction also tolerates higher ripple currents and provides lower impedance at low frequencies (below 1 kHz) compared with stacked SMD alternatives of equivalent total capacitance. For high-ripple-current environments such as motor drives and audio amplifiers operating between -40°C and +85°C, the wet aluminum construction of the ECA1VM332 offers a cost-effective single-component solution.
