254M06QD22

Overview

The 254M06QD22 is a Quencharc RC Snubber Film Capacitor manufactured by Cornell Dubilier Knowles. It integrates a 0.25 µF polyester dielectric capacitor with a 22 Ohm equivalent series resistance (ESR) in a single radial component. The device supports a DC voltage rating of 600 VDC and an AC voltage rating of 250 VAC, with a capacitance tolerance of ±10%. Designed for through-hole mounting, it features straight leads with a 30.5 mm pitch. The unit operates within a temperature range of -40°C to +85°C and measures 36.8 mm in length, 10.6 mm in width, and 19 mm in height.

Feature Summary

• Integrates RC snubber functionality within a single radial package
• Utilizes polyester dielectric for stable electrical performance
• Features built-in resistance for EMI/RFI suppression

Applications

• RC EMI filter circuits
• First-order low-pass filtering applications
• Snubber networks for power electronics

Procurement Notes

Verify the manufacturer designation as Cornell Dubilier or Knowles Illinois Capacitor on official documentation. Confirm the specific part number 254M06QD22 matches the required 22 Ohm ESR and 0.25 µF capacitance values. Ensure the radial lead spacing and physical dimensions align with the target PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a combined RC snubber solution is required for EMI suppression. The integrated design simplifies assembly compared to discrete components. Verify that the 600 VDC rating meets the circuit's peak voltage demands. Ensure the operating temperature range covers the environmental conditions of the application.

Part Context

This component belongs to the Quencharc Q/QRL series of film capacitors. These parts are engineered specifically for high-reliability snubber and filter applications. The series combines capacitor and resistor elements to provide compact solutions for noise reduction in electronic circuits.

Replacement Considerations

Check for other variants in the 254M06QD series with different resistance values if the impedance requirement changes. Verify pin compatibility and physical footprint when considering alternative manufacturers.
