What are the key features of ECA1EM471?

470 µF capacitance at 25 V rating with ±20% tolerance in a compact 10 mm radial body for power rail bulk decoupling
Low leakage current of 0.1175 mA ensuring minimal standby losses in battery-powered and efficiency-critical designs
RoHS compliant (Pb-free, JESD-609 e3 coded) aluminum wet electrolytic construction for long service life and regulatory compliance

What is ECA1EM471 used for?

The ECA1EM471 is widely used as bulk energy storage on 25 V power supply rails in consumer electronics, DC-DC converters, and switching-mode power supplies where 470 µF capacitance smooths rectified voltages and reduces output ripple. Its radial lead format and 10 mm diameter also make it convenient for through-hole power filter stages in industrial control boards, audio amplifiers, and motor-drive circuits.

Frequently Asked Questions

What capacitance and voltage rating does the ECA1EM471 provide for power supply decoupling?

The ECA1EM471 offers 470 µF capacitance at a 25 V rating with ±20% tolerance, making it suitable for bulk decoupling on 12 V to 24 V DC power rails, output ripple filtering in switching regulators, and energy storage in AC-DC rectifier stages.

How does the 10 mm radial body size of the ECA1EM471 affect PCB layout for power filter stages?

The 10 mm diameter radial-leaded body of the ECA1EM471 fits standard through-hole footprints with 5 mm lead pitch, occupying minimal PCB area while delivering 470 µF bulk capacitance, which simplifies layout for compact AC-DC converter output stages and DC bus filter networks.

What is the leakage current of the ECA1EM471, and why does it matter for low-power circuit designs?

The ECA1EM471 has a maximum leakage current of 0.1175 mA, which is important for battery-powered or energy-harvesting designs where excess capacitor leakage directly drains the energy reservoir; at 25 V this leakage dissipates under 3 mW, keeping standby losses low.

Is the ECA1EM471 suitable for use in designs requiring RoHS compliance?

Yes, the ECA1EM471 is fully RoHS compliant with a Pb-free designation and JESD-609 e3 halogen-free coding, making it appropriate for consumer electronics, industrial equipment, and automotive accessory boards that must meet EU RoHS and similar international environmental regulations.
