What are the key features of ECA1EM101?
- 100 µF at 25 V with ±20% tolerance in a compact 6.3 mm radial leaded package for through-hole power filtering
- Low leakage current of 0.025 mA ensures minimal quiescent drain in battery-assisted and low-power circuit designs
- M Series RoHS-compliant aluminum electrolytic construction meets JESD-609 e2 lead-free requirements for modern electronics
What is ECA1EM101 used for?
The ECA1EM101 is widely used as a bulk decoupling and output smoothing capacitor in switching power supplies, DC-DC converters, and audio amplifier power stages operating at up to 25 V. Its 100 µF capacitance and 6.3 mm radial leaded footprint suit through-hole PCBs in consumer electronics, lighting drivers, and industrial power modules. The low 0.025 mA leakage current makes it appropriate for energy-sensitive designs where idle power consumption is a concern.

Frequently Asked Questions
What is the voltage rating and capacitance of the ECA1EM101, and how does this compare to the ECA1CHG101?
The ECA1EM101 is rated 100 µF at 25 V, while the ECA1CHG101 is 100 µF at 16 V. The ECA1EM101's higher 25 V rating provides greater voltage headroom for 12 V to 20 V power rails in DC-DC converters and audio amplifier stages, at the cost of a slightly larger 6.3 mm body diameter.
How does the ECA1EM101 perform in a 5 V USB power supply output filter?
In a 5 V USB output filter, the ECA1EM101's 25 V rating gives a 5x voltage derating margin, well beyond the 2x minimum recommended for long-term reliability. The 100 µF capacitance effectively attenuates switching ripple at 20 kHz to 100 kHz frequencies, and the 0.025 mA leakage current is negligible against the 500 mA to 3 A load current.
What through-hole footprint dimensions should a PCB designer use for the ECA1EM101?
The ECA1EM101 has a 6.3 mm body diameter and requires a 2.5 mm pin-to-pin lead spacing on the PCB footprint. Designers should allow at least 11 mm of component height clearance in the enclosure for the standard M Series body, with the radial leads fitting standard 2.5 mm pitch through-hole pads.
