254M06QD150

Overview

The Cornell Dubilier Knowles 254M06QD150 is a Quencharc RC Snubber Film Capacitor featuring a polyester dielectric and radial termination. It provides a capacitance of 0.25 µF with a DC voltage rating of 600 VDC and an AC voltage rating of 250 VAC. The component integrates a 150 Ohm internal resistor, resulting in a low ESR characteristic suitable for snubbing applications. It operates within a temperature range of -40°C to +85°C and utilizes straight PC pins for through-hole mounting.

Feature Summary

• Integrates a 150 Ohm resistor with the capacitor element for effective RC snubbing
• Utilizes metallized polyester film dielectric for stable performance
• Designed specifically for RC snubber and EMI/RFI filter applications

Applications

• RC Snubber circuits
• EMI/RFI filtering
• Power electronics protection

Procurement Notes

Verify the specific resistance value of 150 Ohms against circuit requirements. Confirm that the radial package dimensions and lead spacing match the PCB layout. Ensure the operating environment stays within the specified -40°C to +85°C temperature range. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a combined RC snubber solution is needed to suppress voltage spikes. The integrated resistor eliminates the need for separate discrete components. Consider the 600 VDC rating for high-voltage DC bus applications. Verify that the 0.25 µF capacitance aligns with the desired frequency response for noise suppression.

Part Context

This part belongs to the Quencharc series from Cornell Dubilier Knowles, specializing in power electronics components. The series is designed for robust performance in industrial and automotive environments. Cornell Dubilier, now part of Knowles Corporation, focuses on high-reliability capacitors for demanding power conversion and motor drive applications.

Replacement Considerations

Substitutes must maintain the 0.25 µF capacitance, 600 VDC rating, and 150 Ohm resistance. Radial packages with compatible lead spacing are required. Verify that alternative parts support the same operating temperature range and snubber application context.
