Key Features
- 3300 µF capacitance at 16 V rating provides substantial bulk energy storage for power supply output filtering and hold-up time in AC/DC converters
- 12.5 mm diameter radial body fits standard through-hole PCB pads with 5 mm lead pitch, simplifying layout for high-capacitance filter stages
- Maximum leakage current of 0.528 mA at rated voltage ensures low standby power loss in switched-mode power supply designs
- RoHS and REACH compliant with JESD-609 e3 moisture sensitivity classification for halogen-free lead-free assembly processes
Applications
The ECA1CHG332 is used as bulk output capacitance in AC/DC power supplies and DC/DC converters, where 3300 µF at 16 V smooths rectified ripple and maintains voltage stability during load transients in industrial and consumer electronics. It also serves as a hold-up capacitor in uninterruptible power supplies and motor drives, providing energy storage during brief input voltage interruptions to allow orderly system shutdown. Audio amplifier power stages leverage its high capacitance to decouple the supply rail from audio frequency current demands, reducing power-supply-rejection-ratio degradation at frequencies below 100 Hz.

Frequently Asked Questions
What capacitance and voltage rating does the ECA1CHG332 provide for power supply filtering applications?
The ECA1CHG332 is a 3300 µF aluminum electrolytic capacitor with a 16 V DC working voltage rating. At this rating it delivers substantial bulk capacitance for smoothing rectified AC to DC ripple at 100 Hz or 120 Hz mains frequency in linear and switched-mode power supplies. A single ECA1CHG332 reduces output ripple voltage by approximately 3 mV per mA of load current at 100 Hz, making it effective for supplies delivering up to 5 A in audio amplifiers, motor controllers, and embedded system power rails.
What is the physical size and lead configuration of the ECA1CHG332, and how does it fit into a standard PCB layout?
The ECA1CHG332 uses a radial leaded package with a 12.5 mm can diameter, a body height of approximately 25 mm, and a standard 5 mm lead pitch spacing. These dimensions conform to IEC 60384 style 1 capacitor footprints, so the part fits directly into through-hole pads prepared for common 3300 µF electrolytic capacitors without re-layout. The radial orientation places both leads on the same side, allowing the capacitor to stand vertically on a horizontal PCB with clearance above the PCB surface for adjacent components at least 13 mm away.
How does the ECA1CHG332 leakage current specification affect standby power consumption in a 16 V powered circuit?
The ECA1CHG332 specifies a maximum leakage current of 0.528 mA at 16 V after 2 minutes of conditioning, which corresponds to a standby power dissipation of 8.4 mW per capacitor. In battery-powered or energy-harvesting systems where every milliwatt matters, this leakage should be accounted for in sleep-mode power budgets. For AC/DC applications with continuous power, the leakage is negligible relative to typical multi-ampere load currents, but paralleling 4 or more capacitors would add 2 mA of leakage that must be supplied by the regulator at no load.
For a 16 V motor-drive supply needing 3300 µF bulk capacitance, how does ECA1CHG332 compare to a film capacitor option?
The ECA1CHG332 aluminum electrolytic achieves 3300 µF in a 12.5 mm x 25 mm radial can, whereas an equivalent 3300 µF film capacitor would occupy a volume roughly 10 times larger and cost 20 to 50 times more. Electrolytic capacitors excel at bulk energy storage for frequencies from DC to 10 kHz but have higher ESR (typically 50 mΩ to 200 mΩ) than film types. For motor-drive applications where ripple frequencies are 20 kHz to 100 kHz, paralleling the ECA1CHG332 with a 100 nF ceramic capacitor handles high-frequency decoupling while the electrolytic provides the 3300 µF bulk hold-up energy.
