Frequently Asked Questions
What is the voltage rating and capacitance value of the ECW-U2103KC9?
The ECW-U2103KC9 has a capacitance of 10nF (0.01µF) and a rated voltage of 100V DC. It features ±10% capacitance tolerance, making it suitable for general-purpose filtering and decoupling applications where moderate precision is acceptable.
Over what temperature range does the ECW-U2103KC9 maintain stable performance?
This PPS film capacitor operates reliably from -40°C to +105°C. The stacked metallized PPS film dielectric provides excellent thermal stability, ensuring capacitance drift stays within a few percent across the full operating range, which is critical for precision filtering circuits.
Which circuit topologies benefit most from the ECW-U2103KC9's low-ESR PPS film design?
Switching power supply output filters, resonant tank circuits, and EMI suppression networks all benefit from the ECW-U2103KC9's low ESR and low dielectric absorption. The 100V rating with 10nF capacitance is particularly effective in flyback converters operating at switching frequencies up to several hundred kHz, where film capacitors outperform ceramic types in distortion.
