Key Features
- Stacked metallized PPS (polyphenylene sulfide) film dielectric provides superior high-frequency stability and low dielectric loss compared to standard polyester film capacitors
- 33 nF capacitance at 100 V rated voltage with ±5% (J-grade) tolerance for precision timing and filter network applications
- Mold-less construction reduces parasitic inductance and capacitance, enabling reliable performance at frequencies up to several hundred MHz
Applications
The ECW-U1333JC9 is used in precision analog filter networks, resonant circuits, and high-frequency coupling applications where low dielectric absorption and stable capacitance over temperature are essential. Its 100 V rating and PPS film dielectric make it suitable for audio crossover networks, switched-mode power supply snubbers, and sensor signal conditioning circuits. The mold-less package minimizes lead inductance for demanding RF and high-speed analog designs.

Frequently Asked Questions
What capacitance, voltage rating, and tolerance does the ECW-U1333JC9 provide?
The ECW-U1333JC9 is rated at 33 nF capacitance with a 100 V DC working voltage and ±5% tolerance (J grade). These specifications suit precision filter and timing circuits where capacitance accuracy within 5% of nominal is required over the operating temperature range of -55°C to +105°C.
Why choose PPS film over standard polyester film for high-frequency filter designs using ECW-U1333JC9?
PPS (polyphenylene sulfide) film offers a lower dissipation factor (tan δ typically below 0.0003 at 1 kHz) compared to polyester film, which can exceed 0.01. For filter networks operating above 100 kHz, the ECW-U1333JC9's PPS dielectric provides more stable capacitance vs. frequency and lower insertion loss, making it preferable in audio equipment and precision RF circuits.
Can ECW-U1333JC9 be used as a snubber capacitor across a MOSFET switch rated at 80 V?
Yes, the ECW-U1333JC9 is well suited for snubber duty at 80 V drain-source voltages, since its 100 V rating provides a 20 V safety margin. The stacked metallized PPS construction handles repetitive high-frequency charge/discharge cycles across a MOSFET switch, and the 33 nF value combined with a series resistor of 1–10 Ω effectively damps switching transients in converters operating up to 500 kHz.
