Key Features
- Stacked metallized PPS (polyphenylene sulfide) film dielectric provides stable capacitance and low dissipation factor over a wide temperature range
- Mold-less simple construction reduces physical stress on the capacitor body, improving long-term reliability in vibration-prone environments
- Low ESR and high Q-factor enable precise filtering, resonant circuit tuning, and coupling in high-frequency applications up to several MHz
Applications
The ECW-U1105KCV is designed for precision filtering, resonant circuit tuning, and coupling applications in audio, power electronics, and industrial equipment where stable capacitance across temperature is critical. Its 100 V rating and 1.0 µF capacitance make it suitable for DC-link decoupling in inverters, snubber networks in switching power supplies, and signal coupling in instrumentation circuits. The PPS dielectric maintains capacitance stability from -55°C to +150°C, outperforming standard polyester film types in demanding thermal environments.

Frequently Asked Questions
What are the capacitance and voltage ratings of the ECW-U1105KCV?
The ECW-U1105KCV is rated at 1.0 µF capacitance and 100 V DC, making it suitable for resonant circuit tuning, snubber networks in switching power supplies, and coupling applications that require stable capacitance under significant voltage stress.
How does the PPS dielectric in the ECW-U1105KCV compare to polyester film capacitors in high-temperature environments?
The PPS (polyphenylene sulfide) dielectric in the ECW-U1105KCV maintains very low capacitance drift from -55°C to +150°C, while standard polyester (PET) film capacitors typically derate above 85°C, giving the ECW-U1105KCV a significant reliability advantage in motor drives, industrial inverters, and automotive electronics.
In which circuit positions does the mold-less construction of the ECW-U1105KCV provide a design advantage?
The mold-less construction eliminates the shrink and stress effects of a conventional molded casing, reducing internal mechanical stress by several percent and improving long-term capacitance stability in vibration-prone installations such as motor-drive PCBs, power inverters, and railway electronics.
