What are the key features of ECA1EM332?

3300 µF high capacitance with 25 V rating ideal for bulk energy storage, power supply filtering, and hold-up circuits in AC/DC converters
16 mm diameter radial-leaded package simplifying through-hole PCB assembly and offering mechanical stability in vibration-prone industrial environments
RoHS and REACH compliant aluminum wet electrolytic construction with low leakage current of 0.825 mA for reliable long-term power supply performance

What is ECA1EM332 used for?

The ECA1EM332 is designed for bulk capacitance applications in switched-mode power supplies, UPS hold-up circuits, and motor drive input filters where 3300 µF at 25 V is required to smooth rectified AC voltage and absorb load transients. Its large 16 mm radial form factor is commonly used in industrial power electronics, audio amplifiers, and LED driver stages that demand high energy storage density. The capacitor also serves as a reservoir element in battery charger output stages and DC bus filtering in variable-frequency drives.

Frequently Asked Questions

What is the capacitance and voltage rating of the Panasonic ECA1EM332?

The ECA1EM332 is rated at 3300 µF with a 25 V maximum working voltage, providing substantial bulk energy storage for power supply filtering, motor drive DC bus decoupling, and UPS hold-up applications where large charge reservoirs are essential.

What are the physical dimensions of the ECA1EM332, and how do they affect PCB layout?

The ECA1EM332 measures 16 mm in diameter as a radial-leaded through-hole component, requiring adequate board clearance for the cylindrical body. This radial package is mechanically stable in high-vibration industrial environments and simplifies hand-soldering or wave-soldering during prototyping and low-to-medium volume production.

How does the ECA1EM332 leakage current specification affect its use in power supply hold-up designs?

The ECA1EM332 specifies a leakage current of 0.825 mA, which must be factored into hold-up time calculations for UPS and ATX power supplies. At 3300 µF and 25 V, the hold-up energy is approximately 1.03 J, so the 0.825 mA leakage represents a negligible load compared to typical output currents in the ampere range, making it well suited for most hold-up and bulk storage designs.
