Feature Summary

• Integrated RC snubber network design for electrical noise suppression
• Polyester metallized film construction for reliability
• Radial through-hole termination for standard PCB mounting

Applications

• Arc suppressor applications
• Snubber networks
• EMI/RFI filtering

Procurement Notes

Verify the specific resistance value associated with the D047 suffix against the official datasheet before procurement. Confirm that the radial package dimensions and lead spacing match the target circuit board layout requirements. Ensure the operating environment remains within the specified -55°C to +85°C temperature range for optimal performance and longevity.

Selection Notes

Select this component when a combined resistor-capacitor snubber solution is required for switching circuits or relay contacts. The integrated design simplifies assembly compared to discrete components. Verify that the 200 VDC rating provides sufficient margin for the application's peak voltage transients. Consider the physical footprint constraints as the radial leads require specific hole spacing on the PCB.

Part Context

This part belongs to the QAS series of arc suppressor and snubber networks from Cornell Dubilier Knowles. These components are specifically engineered to reduce or eliminate electrical arcing, noise, and electromagnetic interference (EMF) in inductive load circuits. The series offers pre-matched RC values to ensure consistent performance across various industrial and commercial switching applications.

Replacement Considerations

Direct replacement requires matching the 0.5 µF capacitance, 200 VDC rating, and the specific internal resistance value. Verify that any substitute maintains the same radial package dimensions and lead spacing to fit existing footprints without modification.
