Overview
The QAS504K200D220 is a first-order RC snubber network manufactured by Cornell Dubilier Knowles. It integrates a 0.5 µF polyester film capacitor with a 220 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. Designed for robust operation, it functions within a temperature range of -55°C to +85°C. The device features a 20.8 mm lead spacing and utilizes a bulk packaging format.
Feature Summary
- Integrates RC snubber network functionality for EMI and RFI suppression
- Utilizes polyester dielectric for stable capacitance performance
- Radial termination style facilitates through-hole mounting
Applications
- EMI and RFI suppression circuits
- High pulse and dv/dt snubbing applications
- General purpose snubber networks
Procurement Notes
Verify the specific suffix code against official datasheets to confirm internal resistance values, as variations exist within the series. Confirm RoHS compliance status directly with the manufacturer documentation prior to integration. Ensure thermal ratings align with the intended operating environment limits defined in the technical specifications.
Selection Notes
Select this component when a compact, integrated solution for transient voltage suppression is required. The fixed 220 Ohm resistance paired with 0.5 µF capacitance targets specific damping requirements. Verify that the radial lead spacing matches the PCB layout constraints and that the voltage ratings exceed the circuit's peak operating conditions.
Part Context
This part belongs to the QAS series of RC snubber networks from Cornell Dubilier Knowles. These components are engineered to replace discrete resistor-capacitor combinations, saving board space and assembly time. The series is designed for reliability in demanding electronic environments requiring effective noise reduction.
Replacement Considerations
QAS504K200D100 serves as a variant within the same series with different internal resistance characteristics.
