Applications
The ECA1EM102 is commonly used as a bulk decoupling capacitor on the output stage of DC-DC converters, linear regulators, and motor drive power supplies operating up to 25 V. Its 1000 µF capacitance handles large transient load currents and suppresses low-frequency ripple voltage on 12 V to 24 V power rails in consumer electronics and industrial control equipment. The radial 10 mm through-hole form factor fits standard electrolytic footprints on power boards in audio amplifiers, LED drivers, and uninterruptible power supplies.

Frequently Asked Questions
What is the capacitance and voltage rating of the ECA1EM102 and what tolerance does it carry?
The ECA1EM102 has a capacitance of 1000 µF rated at 25 V with a ±20% tolerance. The leakage current is 0.25 mA, and the 10 mm diameter radial body suits standard electrolytic PCB footprints used in power supply output stages and bulk decoupling networks.
Which power supply topologies benefit most from the 1000 µF ECA1EM102 output capacitor?
Buck converters, linear regulators, and flyback power supplies operating at up to 25 V output benefit from the 1000 µF ECA1EM102 as the primary output filter capacitor. The large capacitance reduces peak-to-peak voltage ripple and handles step-load transients on 5 V, 12 V, and 24 V rails common in embedded systems and industrial motor drivers.
How does the 10 mm body diameter of ECA1EM102 fit standard PCB footprints?
The ECA1EM102's 10 mm diameter radial can is one of the most common electrolytic capacitor body sizes, compatible with IPC-7251 standardized through-hole footprints for 10 mm diameter electrolytic capacitors. Standard lead spacing for this diameter is typically 5 mm pitch, allowing drop-in replacement with other 1000 µF 25 V radial electrolytic capacitors of the same diameter.
When should a designer consider replacing ECA1EM102 with a solid polymer capacitor?
A designer should consider switching from the ECA1EM102 aluminum wet electrolytic to a solid polymer capacitor when operating temperatures exceed 85°C continuously, when ESR must remain below a few milliohms for high-frequency ripple filtering above 100 kHz, or when a lifetime beyond 2000 hours at rated temperature is required. Polymer capacitors offer lower ESR and longer lifespan but at higher cost per µF at the 1000 µF 25 V rating.
