Frequently Asked Questions
What is the capacitance and voltage rating of the ECW-U2124KC9?
The ECW-U2124KC9 has a capacitance of 0.12 µF (120 nF) and is rated for 100 V DC operation. The tolerance is ±10% (K grade), making it suitable for decoupling and filtering applications in power conversion circuits where precise capacitance values are required.
Up to what operating temperature can the ECW-U2124KC9 be used in automotive or industrial designs?
The ECW-U2124KC9 uses a PPS (polyphenylene sulfide) film dielectric that allows continuous operation up to 150°C, significantly higher than standard polyester film capacitors rated to 85°C or 105°C. This thermal stability makes it a strong choice for under-hood automotive electronics and high-ambient industrial environments.
How does the mold-less construction of the ECW-U2124KC9 benefit PCB assembly?
The mold-less stacked film construction of the ECW-U2124KC9 results in a compact body with reduced parasitic inductance, improving high-frequency performance above 1 MHz. The simplified mechanical structure also lowers the risk of thermal stress cracking compared to encapsulated capacitors, contributing to longer service life in 100 V DC applications.
