Procurement Notes

Verify the specific suffix codes against official Cornell Dubilier Knowles documentation to confirm exact tolerance and termination specifications. Ensure the selected variant meets the required thermal and voltage derating standards for the target application environment. Cross-reference datasheet revisions to guarantee compatibility with existing design constraints.

Selection Notes

Select this component when a combined capacitive and resistive damping solution is required for high-voltage switching applications. The 47 Ohm internal resistance is critical for limiting peak currents during discharge events. Consider the physical dimensions and lead spacing to ensure adequate clearance and creepage distances on the printed circuit board layout.

Part Context

This part belongs to the Quencharc family of RC snubber capacitors from Cornell Dubilier Knowles. These components are engineered to replace discrete resistor-capacitor combinations, saving board space and assembly time. The series is widely used in power electronics to protect semiconductor devices from voltage spikes and reduce electromagnetic interference generated by rapid switching transitions.

Replacement Considerations

Direct substitutes must match the 0.1 µF capacitance, 47 Ohm resistance, and 600 VDC rating. Verify that alternative parts maintain the same radial package dimensions and lead pitch to fit existing footprints without mechanical modification.
