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.
