What are the key features of ECW-U4124V17?
- 0.12 µF capacitance at 400 VDC rating with PEN (polyethylene naphthalate) film dielectric for stable high-voltage operation
- Tight ±5% capacitance tolerance ensuring precise filtering and coupling performance in AC line and power conversion circuits
- Compact 3931 non-polarized surface-mount package enabling use in both AC and DC high-voltage filtering applications
What is ECW-U4124V17 used for?
The ECW-U4124V17 is designed for AC filtering, DC blocking, and coupling applications in power electronics, including switching power supplies, motor drive inverters, and solar inverters where 400 VDC rated capacitors are required. Its PEN film dielectric provides excellent capacitance stability over temperature and frequency compared to ceramic alternatives in high-voltage circuits. The non-polarized chip package suits both AC and DC circuit configurations without orientation constraints during PCB assembly.

Frequently Asked Questions
What capacitance and voltage rating does the ECW-U4124V17 provide, and is it suitable for 230 VAC line applications?
The ECW-U4124V17 provides 0.12 µF at 400 VDC, which corresponds to a peak AC voltage rating of approximately 280 VAC, making it marginally suitable for 230 VAC line filtering with sufficient derating margin when used with proper snubber circuit design.
How does the PEN film dielectric in the ECW-U4124V17 compare to MLCC ceramic capacitors at high voltage?
PEN film capacitors like the ECW-U4124V17 maintain stable 0.12 µF capacitance across the rated 400 VDC without the DC bias-induced capacitance drop of 50-80% seen in X5R MLCC ceramics, making them preferable for precision filtering and snubber circuits in power converters.
What tolerance class does the ECW-U4124V17 carry, and in what package does it ship?
The ECW-U4124V17 is rated at ±5% capacitance tolerance (J grade) and comes in a 3931 surface-mount chip package measuring approximately 3.9 mm × 3.1 mm, supporting reflow soldering assembly for compact high-voltage power supply PCB designs.
