Frequently Asked Questions
What voltage and capacitance ratings does the ECW-U1182JX5 offer for high-voltage filtering circuits?
The ECW-U1182JX5 offers a 1000 V DC voltage rating with a nominal capacitance of 1800 pF, making it suitable for high-voltage resonant and filtering applications. Its PPS film dielectric ensures low dielectric loss (tan delta) compared to polyester alternatives, reducing heat generation in high-frequency power converter snubber circuits.
Over what temperature range does the ECW-U1182JX5 maintain stable capacitance for precision circuit designs?
The ECW-U1182JX5 PPS film capacitor maintains stable capacitance across a wide temperature range of -55°C to +125°C with low temperature coefficient drift. This stability makes it a preferred choice over X7R ceramic capacitors in precision timing and filter circuits where capacitance variation with temperature would introduce measurement or frequency errors.
How does the mold-less construction of the ECW-U1182JX5 benefit RF and switching applications compared to molded film capacitors?
The mold-less construction of ECW-U1182JX5 reduces parasitic inductance and enables a lower equivalent series inductance (ESL), which improves high-frequency performance above 1 MHz. In switching power supplies and RF filters, lower ESL translates to better noise suppression at higher frequencies, making this 1800 pF capacitor effective for EMI filtering up to tens of MHz.
