What are the key features of ECW-U1104KC9?
- Stacked metallized PPS film dielectric provides ultra-low ESR and excellent capacitance stability across -55 °C to +150 °C operating range
- 100 V DC rated voltage with 100 nF capacitance and ±10% tolerance delivering precise filtering in high-frequency circuits
- Mold-less simple construction minimises parasitic inductance and reduces overall package size for space-constrained PCB designs
- PPS film dielectric exhibits near-zero capacitance change with temperature, outperforming standard polyester and polypropylene types in precision applications
What is ECW-U1104KC9 used for?
ECW-U1104KC9 is used in high-frequency filter networks, resonant tank circuits, and precision timing circuits where PPS film's ultra-stable capacitance across temperature is critical. Its 100 V rating and low ESR make it suitable for switching power supply snubber networks and EMI suppression filters in industrial drives and inverters. The capacitor also appears in audio crossover networks and medical instrumentation where minimal capacitance drift at frequencies up to several megahertz is required.

Frequently Asked Questions
What is the capacitance, voltage rating, and tolerance of ECW-U1104KC9?
ECW-U1104KC9 is rated at 100 nF capacitance with a 100 V DC working voltage and ±10% (K-grade) tolerance, making it suitable for coupling, decoupling, and filtering applications in circuits where capacitance accuracy within 10 nF is sufficient.
How does the PPS film dielectric in ECW-U1104KC9 compare to standard polyester capacitors for thermal stability?
PPS (polyphenylene sulfide) film exhibits a capacitance temperature coefficient near 0 ppm/°C across the -55 °C to +150 °C range, meaning ECW-U1104KC9 maintains its 100 nF value far more consistently than typical polyester capacitors that can drift by several percent over the same temperature span.
For which circuit categories is the low ESR of ECW-U1104KC9 most beneficial?
The metallized PPS film construction gives ECW-U1104KC9 extremely low equivalent series resistance, making it ideal for high-frequency snubber networks across IGBT and MOSFET switches, resonant LLC converter tank circuits operating above 100 kHz, and precision RC filter stages where resistive losses must be kept below a few milliohms.
What operating temperature range does ECW-U1104KC9 support and what design applications does this enable?
ECW-U1104KC9 operates from -55 °C to +150 °C, allowing it to be placed close to heat-generating power semiconductors in motor drive inverters and industrial automation controllers without derating the 100 V rating or experiencing significant capacitance shift.
