504M02QA22

Overview

The Paktron 504M02QA22 is a through-hole EMI/RFI filter component belonging to the Quencharc series. It utilizes multilayer polymer film construction for self-healing capabilities and high reliability. The unit features a capacitance of 0.22 µF with a voltage rating of 200V DC. It operates within a temperature range of -55°C to +85°C. The physical dimensions are 1.079 inches in length by 0.370 inches in width, designed for radial lead mounting.

Feature Summary

• Multilayer polymer construction providing superior mechanical stability and electrical performance compared to traditional wound film capacitors.
• Self-healing dielectric properties that maintain functionality after minor internal faults, serving as a robust alternative to ceramic components.
• High ripple current handling capability suitable for demanding filtering applications in power electronics.

Applications

• EMI filtering in general-purpose electronic circuits
• LC filtering networks for power converters
• RC snubber circuits for switching mode power supplies

Procurement Notes

Verify the specific package dimensions and lead spacing against your PCB footprint requirements before ordering. Confirm that the 200V DC rating meets the peak voltage stresses of your target application circuit. Ensure compatibility with the specified operating temperature range of -55°C to +85°C for your environmental conditions.

Selection Notes

Select this component when a self-healing, high-reliability filter capacitor is required for EMI suppression. The multilayer polymer technology offers better pulse current handling than standard polyester films. Consider this part for space-constrained designs where radial leads provide a compact solution for LC or RC network integration.

Part Context

This component is part of the Paktron Quencharc line, which specializes in multilayer polymer film capacitors. The brand has over 60 years of experience in capacitor innovation, focusing on advanced stacked designs that outperform traditional wound films. This series is engineered for durability and consistent performance in industrial and commercial electronics.

Replacement Considerations

Direct substitutes must match the 0.22 µF capacitance, 200V DC rating, and radial through-hole package. Verify that any replacement also utilizes multilayer polymer construction if self-healing properties are critical. Ensure the substitute component meets the same -55°C to +85°C temperature specification.
