Frequently Asked Questions
How does the PPS film dielectric in ECW-U1392JX5 compare to X7R ceramic capacitors for high-frequency filtering?
PPS film capacitors like ECW-U1392JX5 exhibit very low dissipation factor (typically below 0.05%) and stable 3900 pF capacitance across frequency, outperforming X7R ceramics which can lose up to 80% capacitance under DC bias and exhibit piezoelectric noise.
What temperature range can ECW-U1392JX5 sustain in an industrial sensor interface circuit?
Panasonic ECW-U series PPS capacitors are typically rated from -40°C to +105°C, providing stable 3900 pF performance across the full industrial temperature range without significant capacitance drift or increased loss tangent.
For a 100 kHz resonant converter, does the low-loss characteristic of ECW-U1392JX5 reduce heat generation in the tank circuit?
Yes. ECW-U1392JX5 features a very low dissipation factor at frequencies up to 1 MHz, which minimizes reactive current losses in 100 kHz resonant tank circuits. This reduces component self-heating, improving efficiency and extending the capacitor's service life in power conversion designs.
