QAS104K200D680

Overview

The QAS104K200D680 is a radial leaded RC snubber network manufactured by Cornell Dubilier Knowles. It integrates a 0.1 µF polyester film capacitor with a 680 Ohm resistor in a single component package. The unit is rated for 200 VDC and operates within a temperature range of -55°C to +85°C. Key electrical specifications include a capacitance tolerance of ±10% and an equivalent series resistance (ESR) of 680 Ohms. The physical dimensions feature a lead spacing of 20.8 mm, designed for through-hole mounting.

Feature Summary

• Integrated RC snubber network combining a 0.1 µF capacitor and 680 Ohm resistor
• Polyester dielectric material for stable performance
• Radial through-hole construction for standard PCB mounting

Applications

• EMI/RFI suppression circuits
• RC snubber networks for switching applications
• General electronic filtering

Procurement Notes

Verify the specific part number QAS104K200D680 against official manufacturer documentation to confirm current availability status and compliance declarations. Ensure that the integrated resistor value and capacitance rating match the circuit requirements precisely. Cross-reference datasheets for thermal derating curves and maximum voltage limits before finalizing procurement decisions.

Selection Notes

Select this component when a compact, pre-matched RC network is required for snubbing or filtering. The radial package suits through-hole assembly processes. Confirm that the 200 VDC rating and 680 Ohm resistance are appropriate for the target voltage levels and damping requirements. Verify environmental operating limits align with the application's thermal profile.

Part Context

This component belongs to the QAS series of film capacitors from Cornell Dubilier Knowles. The series focuses on EMI/RFI filtering solutions utilizing polyester dielectrics. These parts are designed as complete networks rather than standalone passive components, simplifying bill-of-materials and assembly for noise suppression tasks.

Replacement Considerations

Direct substitutes must maintain identical capacitance (0.1 µF), resistance (680 Ohms), voltage rating (200 VDC), and package type. Verify lead spacing compatibility if replacing on existing boards.
