QAS504K200D022

Overview

The QAS504K200D022 is a first-order RC snubber network manufactured by Cornell Dubilier Knowles. It integrates a 0.5 µF polyester film capacitor with a 22 Ohm resistor in a single radial component. The unit supports a DC voltage rating of 200 VDC and an AC voltage rating of 125 VAC. It features a 10% capacitance tolerance and operates within a temperature range of -55°C to +85°C. The device utilizes straight leads with a 20.8 mm pitch for through-hole mounting.

Feature Summary

• Integrates RC snubber network functionality into a compact radial package
• Designed to reduce or eliminate electrical arcing, noise, and EMF
• Utilizes polyester dielectric for stable performance

Applications

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

Procurement Notes

Verify the specific resistance value associated with the suffix D022 against the official datasheet before procurement. Confirm that the integrated 22 Ohm resistor meets the circuit requirements. Ensure the 20.8 mm lead spacing matches the PCB layout. Check RoHS compliance status via the manufacturer's documentation.

Selection Notes

Select this component when a combined RC snubber solution is required for voltage spike suppression. The 0.5 µF capacitance and 22 Ohm resistance are fixed internal values. Verify that the 200 VDC rating exceeds the peak transient voltages in the application. Ensure the operating environment remains within the specified -55°C to +85°C thermal limits.

Part Context

This part belongs to the QAS series of arc suppressor and snubber networks from Cornell Dubilier Knowles. These components are engineered to replace discrete resistor-capacitor assemblies, saving board space. The series is designed for harsh environments requiring reliable noise reduction and contact protection.

Replacement Considerations

Direct substitutes include other QAS series variants with different resistance values, such as QAS504K200D033. Cross-brand replacements require matching the 0.5 µF capacitance, 200 VDC rating, and 22 Ohm resistance in a radial package.
