Key Features
- 3300 µF at 50 V with ±20% tolerance delivering high bulk energy storage for large power supply filtering and hold-up circuits
- Radial leaded 18 mm diameter through-hole package enabling robust PCB mounting with low ESR for high-ripple-current applications
- Pb-free and REACH-compliant construction meeting RoHS requirements for environmentally sensitive industrial and consumer power supply designs
Applications
ECA1HM332 is well suited for bulk energy storage in 50 V power supply output stages, such as those found in industrial servo drives, audio amplifiers, and UPS hold-up circuits where 3300 µF capacitance smooths large current transients. The 18 mm radial can fits standard PCB through-hole layouts common in high-power converters and motor control inverter platforms. Its high capacitance density and wet aluminum electrolytic chemistry make it effective for line frequency ripple filtering at 50 Hz to 120 Hz in transformer-based power supplies.

Frequently Asked Questions
What capacitance and voltage rating does ECA1HM332 offer, and what is its leakage current?
ECA1HM332 is rated at 3300 µF and 50 V with a ±20% capacitance tolerance and a maximum leakage current of 1.65 mA. This combination makes it suitable for bulk reservoir capacitors in 50 V power supplies where high capacitance and moderate leakage are acceptable trade-offs.
Which power conversion topologies benefit most from ECA1HM332 at their output stages?
ECA1HM332 is ideal for the output reservoir stage of full-bridge or half-bridge rectifiers in 48 V to 50 V transformer-based power supplies, where 3300 µF capacitance reduces 100 Hz or 120 Hz ripple voltage to acceptable levels. It also serves as a bulk input cap in servo motor drives and industrial inverters drawing several amperes of peak current.
What is the diameter and lead style of ECA1HM332, and how does it mount on a PCB?
ECA1HM332 has an 18 mm diameter cylindrical body with radial leads, designed for through-hole PCB mounting. The through-hole footprint provides strong mechanical retention compared to SMD variants, making it reliable in vibration-prone environments such as motor control cabinets and industrial UPS installations.
What is the factory lead time for ECA1HM332, and how should procurement teams plan for it?
ECA1HM332 carries a 19-week factory lead time from Panasonic. Procurement teams building power supply assemblies should place orders at least 5 months ahead of production start dates or maintain a safety stock buffer of 8 to 12 weeks to avoid line stoppages during demand spikes.
