Key Features
- 10 nF capacitance at 200 V DC rating with ±5% (J) tolerance using stacked metallized PPS film dielectric for stable precision performance
- PPS film dielectric provides near-zero temperature coefficient and extremely low dielectric absorption, ideal for sample-and-hold and timing circuits
- Mold-less radial lead construction with compact body dimensions enabling direct through-hole PCB mounting in tight board layouts
Applications
The ECW-U2103JC9 is used in precision analog filter stages, audio crossover networks, and switching power supply snubber circuits where stable 10 nF capacitance at 200 V DC is required. Its PPS dielectric ensures minimal capacitance drift across temperatures from -55°C to +125°C, making it appropriate for automotive electronics and industrial instrumentation. The radial lead package fits standard 5 mm or 7.5 mm PCB footprints commonly used in through-hole filter and timing circuit assemblies.

Frequently Asked Questions
What capacitance, voltage rating, and tolerance does the ECW-U2103JC9 provide?
The ECW-U2103JC9 is a 10 nF (10,000 pF) PPS film capacitor rated for 200 V DC with a ±5% tolerance (J grade). These specifications make it suitable for precision filtering, timing, and snubber applications where capacitance accuracy within 5% must be maintained over the operating voltage range.
Why is PPS film the preferred dielectric for sample-and-hold and precision timing circuits over standard polyester film?
PPS (polyphenylene sulfide) film has an extremely low dielectric absorption coefficient—typically below 0.05%—compared to 0.2% to 0.5% for polyester (PET) film. In sample-and-hold circuits, this means the ECW-U2103JC9 releases less than 0.05% of stored charge back into the signal path after sampling, giving measurement errors below 1 mV on a 5 V held voltage.
Over what temperature range does the ECW-U2103JC9 maintain capacitance stability?
The ECW-U2103JC9 maintains capacitance within its rated ±5% tolerance across an operating temperature range of -55°C to +125°C, with a near-zero temperature coefficient of capacitance (TCC) well below ±250 ppm/°C. This thermal stability makes it a reliable choice in automotive under-hood electronics and industrial equipment exposed to wide ambient temperature swings.
What PCB footprint pitch does the ECW-U2103JC9 use and how does its body size compare to equivalent MLCC capacitors?
The ECW-U2103JC9 uses a radial lead pitch of 5 mm or 7.5 mm depending on body size, with a body length of approximately 7 mm and diameter of about 4 mm. This is physically larger than a 0402 or 0603 MLCC of the same 10 nF value, but the PPS film construction provides far superior voltage linearity and dielectric absorption performance that MLCCs rated at 200 V DC cannot match at comparable cost.
