QAS254K600D022

Overview

The QAS254K600D022 is a first-order RC snubber network manufactured by Cornell Dubilier Knowles. It features a capacitance of 0.25 µF and a resistance of 22 Ohms. The component is rated for AC voltages between 275 VAC and 310 VAC, with specific listings indicating a 250 VAC rating. It utilizes self-healing metallized polypropylene film technology and is housed in a radial through-hole package.

Feature Summary

• Integrates resistor and capacitor into a single RC snubber network unit
• Utilizes self-healing metallized polypropylene film dielectric
• Designed to reduce or eliminate electrical arcing and electromagnetic interference

Applications

• Arc suppression in switching circuits
• EMI/RFI noise filtering
• Snubber networks for inductive loads

Procurement Notes

Verify the specific voltage rating required for your application against the datasheet, as sources indicate ratings ranging from 250 VAC to 310 VAC. Confirm that the radial through-hole package dimensions are compatible with your PCB layout. Ensure the 22 Ohm resistance and 0.25 µF capacitance values meet the circuit's snubber requirements.

Selection Notes

Select this component when a compact, integrated solution for arc suppression is needed. The metallized polypropylene construction offers reliability and self-healing properties suitable for harsh environments. Consider the radial lead configuration for standard through-hole mounting processes.

Part Context

This part belongs to the QAS series of arc suppressor and snubber networks from Cornell Dubilier Knowles. These components are engineered to handle high-voltage transients and provide effective noise reduction in industrial and automotive applications where electrical arcing is a concern.

Replacement Considerations

Ensure any substitute maintains the 0.25 µF capacitance and 22 Ohm resistance values. Verify that the replacement component supports the same AC voltage rating (250-310 VAC) and utilizes a similar radial package for mechanical compatibility.
