What are the key features of ECW-U2102KC9?
- Stacked metallized PPS film dielectric delivers superior temperature stability and low dielectric absorption compared to polyester or polypropylene film capacitors
- 200 V DC rated voltage in a mold-less compact body suitable for high-voltage analog and signal-conditioning circuits
- ±10% capacitance tolerance with 1000 pF nominal value ensures consistent performance in precision resonant and filter applications
What is ECW-U2102KC9 used for?
The ECW-U2102KC9 is used in precision analog filter networks, sample-and-hold circuits, and resonant frequency-selective circuits where PPS film's low dielectric absorption and stable capacitance from -55°C to +150°C are essential. Its 200 V DC rating and 1000 pF value suit high-voltage coupling and decoupling networks in power conversion feedback paths and motor drive gate circuits. Measurement and test equipment designers also select this capacitor for its low ESR and minimal self-heating in AC signal conditioning stages.

Frequently Asked Questions
What voltage and capacitance does the Panasonic ECW-U2102KC9 provide and for which circuit categories is it best suited?
The ECW-U2102KC9 is a 1000 pF capacitor rated at 200 V DC with ±10% tolerance, making it appropriate for high-voltage analog signal chains, precision filter networks, and resonant circuits operating up to 200 V. Its PPS film dielectric provides a temperature coefficient of approximately ±150 ppm/°C, giving stable 1000 pF capacitance across the -55°C to +150°C operating range required in power electronics and precision instrumentation.
Why is PPS film preferred over polyester or polypropylene film in the ECW-U2102KC9 for precision applications?
PPS (polyphenylene sulfide) film offers significantly lower dielectric absorption (typically below 0.05%) compared to polyester film (0.2% to 0.5%), which means the ECW-U2102KC9 releases less stored charge after switching, improving accuracy in sample-and-hold circuits and integrators. PPS also retains stable capacitance up to 150°C where polypropylene film begins to degrade above 105°C, giving the ECW-U2102KC9 an extended operating temperature advantage of at least 45°C over polypropylene alternatives.
How does the mold-less construction of the ECW-U2102KC9 benefit PCB assembly and thermal performance?
The mold-less construction of the ECW-U2102KC9 eliminates the additional epoxy resin overmold layer found in standard film capacitors, resulting in a smaller body volume and reduced thermal mass. This allows the 1000 pF, 200 V capacitor to dissipate heat more efficiently in high-frequency AC applications and reduces the mechanical stress on solder joints during thermal cycling between -55°C and +150°C, improving long-term reliability on densely populated PCBs.
Can the ECW-U2102KC9 replace a ceramic NP0 capacitor in a 200 V precision timing circuit?
The ECW-U2102KC9 is a viable alternative to NP0 ceramic capacitors in 200 V timing circuits for capacitance values around 1000 pF, as PPS film offers comparable temperature stability (±150 ppm/°C) and lower dielectric absorption than NP0 ceramics. However, PPS film capacitors are physically larger than equivalent SMD ceramic NP0 capacitors in 0402 or 0603 case sizes, so designers must verify the PCB footprint accommodates the ECW-U2102KC9's leaded radial package before substituting.
