Frequently Asked Questions
What voltage and capacitance rating does EKXJ401ELL220MJ25S offer for high-voltage power supply designs?
The EKXJ401ELL220MJ25S provides 22 µF of capacitance at a 400 V DC rating, making it well-suited for AC-DC power supply bulk filter capacitor positions on PFC output stages operating from 85 V to 265 V AC input ranges where the rectified bus voltage reaches 380 V to 400 V DC.
How does the 10 mm diameter radial package affect PCB layout in high-voltage designs?
The EKXJ401ELL220MJ25S uses a 10 mm diameter through-hole radial package with 5 mm lead pitch, which fits standard high-voltage PCB footprints while maintaining sufficient clearance to nearby components at 400 V operating potentials, simplifying layout in motor inverters, industrial SMPS, and PFC boost converter circuits.
What leakage current specification should engineers expect from EKXJ401ELL220MJ25S in standby operation?
The EKXJ401ELL220MJ25S has a maximum leakage current of 0.452 mA at rated 400 V DC, which represents a controlled self-discharge characteristic important in energy storage and hold-up capacitor applications within industrial power supplies and UPS systems where low standby losses are required.
When is EKXJ401ELL220MJ25S a better choice than a film capacitor for a 400 V filtering application?
The EKXJ401ELL220MJ25S offers 22 µF at 400 V in a compact 10 mm radial package at much lower cost than a film capacitor of equivalent capacitance and voltage rating, making it the preferred choice for bulk energy storage and low-frequency ripple filtering in SMPS and motor drive designs where electrolytic capacitors are well within the ripple current and temperature specifications.
