What are the key features of ECEC2EP102DJ?
- High 250 V DC voltage rating combined with 1000 µF large capacitance supports bulk energy storage in industrial-grade power supplies and motor drives
- Through-hole radial 30 mm × 50 mm form factor provides mechanical stability for high-capacitance, high-voltage applications on PCBs
- Low leakage current of 1.5 mA and aluminum wet electrolyte construction ensure reliable long-term performance at up to +85°C
What is ECEC2EP102DJ used for?
The ECEC2EP102DJ is designed for bulk energy storage and filtering in high-voltage power supplies, inverters, and industrial motor drive systems operating at up to 250 V DC. Its large 1000 µF capacitance stabilizes DC bus rails and smooths rectified AC waveforms in AC-to-DC converters and UPS systems. The through-hole package is well-suited for chassis-mounted or panel-mount power electronics where mechanical robustness and high ripple current handling are important.

Frequently Asked Questions
What voltage and capacitance ratings does the ECEC2EP102DJ provide for power supply filtering?
The ECEC2EP102DJ is rated at 250 V DC with 1000 µF capacitance, making it suitable for bulk filtering on high-voltage DC bus rails in industrial power supplies and AC-to-DC converters. Its large capacitance helps reduce ripple voltage and stores sufficient energy to maintain rail stability during load transients.
How does the 30 mm diameter and 50 mm height of ECEC2EP102DJ affect PCB layout in a power inverter?
The through-hole radial package measures 30 mm in diameter and 50 mm in height, requiring a dedicated 10 mm lead pitch footprint and adequate vertical clearance on the PCB. In power inverters, this large physical size must be planned into the chassis layout, but it also provides mechanical stability and the thermal mass needed to handle continuous ripple currents at up to +85°C.
At what maximum temperature can the ECEC2EP102DJ operate, and what does that mean for UPS applications?
The ECEC2EP102DJ is rated for operation up to +85°C. In UPS systems mounted in warm equipment enclosures, this rating supports continuous duty in ambient temperatures typical of industrial environments without requiring additional cooling beyond standard ventilation. Engineers should verify that ripple current heating does not raise the component temperature above this +85°C limit.
When would a designer choose ECEC2EP102DJ over a film capacitor for a 250 V DC motor drive DC link?
Aluminum electrolytic capacitors like the ECEC2EP102DJ provide 1000 µF in a compact 30 mm × 50 mm through-hole package, offering far higher capacitance density than film capacitors of comparable voltage and size. This makes them preferred for motor drive DC link filtering where large bulk energy storage is needed to reduce voltage ripple below 5%, whereas film capacitors are used where longer lifetime or higher ripple current ratings outweigh the capacitance advantage.
