What are the key features of ECEC1JA103EJ?
- Large 10000 µF capacitance at 63 V rating for robust bulk energy storage and filtering
- High-temperature rating of +105°C ensuring long operational life in demanding power supply environments
- Through-hole radial mount in 35 mm x 50 mm body for secure PCB installation in high-current applications
What is ECEC1JA103EJ used for?
The ECEC1JA103EJ is designed for bulk energy storage, hold-up capacitance, and low-frequency ripple filtering in industrial and commercial power supply units. Its 10000 µF capacitance at 63 V makes it well-suited for smoothing rectified DC in switched-mode and linear power supplies operating up to 63 V. The +105°C temperature rating also makes it appropriate for use in motor drives, UPS systems, and audio amplifier power stages where thermal stress is a concern.

Frequently Asked Questions
Can ECEC1JA103EJ handle ripple current in a 48 V industrial SMPS design?
The ECEC1JA103EJ is rated for 63 V DC and provides 10000 µF of capacitance, making it capable of absorbing significant ripple current in a 48 V SMPS. Its aluminum wet electrolytic construction and +105°C temperature rating ensure reliable operation under continuous ripple current stress in industrial power supply designs.
What are the physical dimensions of the ECEC1JA103EJ and how do they affect PCB layout?
The ECEC1JA103EJ measures 35 mm in diameter and 50 mm in height with a 10 mm lead pitch for through-hole mounting. Designers must allocate sufficient vertical clearance and ensure the 10 mm pin spacing matches the PCB footprint to maintain proper alignment and mechanical stability in power supply assemblies.
How does the leakage current of ECEC1JA103EJ compare to design requirements in hold-up circuits?
The ECEC1JA103EJ has a specified leakage current of 2.38 mA, which designers must account for in hold-up time calculations. In systems where a 10000 µF reservoir must sustain voltage above a threshold for several milliseconds after a mains dropout event, even a 2.38 mA self-discharge path can reduce effective hold-up duration at 63 V.
