504M06QE22

Overview

The Cornell Dubilier Knowles 504M06QE22 is a Quencharc RC Snubber Film Capacitor featuring a polyester dielectric. It provides a capacitance of 0.5 µF with an integrated series resistance of 22 Ohms. The component supports a DC voltage rating of 600 VDC and an AC voltage rating of 250 VAC. It utilizes a radial through-hole package with a 30.5 mm lead spacing. The unit operates within a temperature range of -40°C to +85°C and carries a tolerance of ±20%.

Feature Summary

• Integrated RC network combining 0.5 µF capacitance with 22 Ohm resistance for snubber applications
• Quencharc construction designed for high reliability in power electronics environments
• Radial leaded configuration suitable for standard through-hole mounting processes

Applications

• RC snubber circuits for switching power supplies
• EMI/RFI filtering in industrial motor drives

Procurement Notes

Verify the specific Quencharc series designation and lead spacing against the official datasheet before integration. Confirm that the 22 Ohm internal resistance aligns with the target snubber damping requirements. Ensure the operating environment remains within the specified -40°C to +85°C thermal limits to maintain performance integrity.

Selection Notes

Select this component when a combined capacitive and resistive element is required for transient suppression. The integrated design reduces board space compared to discrete RC networks. Verify that the 600 VDC rating exceeds the peak circuit voltages. Consider the radial footprint dimensions for PCB layout constraints.
