Frequently Asked Questions

What capacitance and voltage rating does the ECW-U2822KC9 provide for high-frequency filter circuits?

The ECW-U2822KC9 provides 8200pF capacitance at a 250V DC voltage rating, making it well suited for high-frequency filter and resonance circuits operating in power electronics and precision audio equipment. The PPS film dielectric ensures this capacitance remains stable across a wide temperature range, typically from -40°C to 105°C, with minimal drift.

How does the PPS dielectric in ECW-U2822KC9 compare to polyester or polypropylene film capacitors for temperature stability?

The PPS (polyphenylene sulfide) dielectric used in ECW-U2822KC9 delivers superior temperature coefficient compared to polyester film, typically within ±100ppm/°C across the -40°C to 105°C operating range. Polypropylene offers similarly low dissipation factor but is limited to about 85°C maximum, while PPS film can operate reliably at 105°C continuous, making it the preferred choice for automotive and industrial applications with elevated ambient temperatures.

In what circuit topologies is the ECW-U2822KC9 most commonly deployed in automotive power systems?

The ECW-U2822KC9 is commonly used in automotive inverter snubber circuits, DC bus filtering, and EMI suppression networks operating at 250V DC or lower. Its 8200pF capacitance and self-healing metallized electrodes make it reliable in Class X and Class Y filter networks, pulse-withstanding snubber positions across power switching devices, and precision timing and resonance circuits in engine control units.

What procurement considerations apply to sourcing ECW-U2822KC9 in volume for a production program?

The ECW-U2822KC9 is a specialty PPS film capacitor from Panasonic with typically longer lead times of 12 to 22 weeks from distribution. Buyers planning production programs should request last-time-buy notices from Panasonic or authorized distributors, verify RoHS compliance documentation for EU market requirements, and consider qualifying alternative PPS capacitors in the 8200pF to 10nF, 250V range as buffer stock for supply risk mitigation.
