Overview
The QAS504K600D022 is a radial leaded RC snubber network capacitor manufactured by Cornell Dubilier Knowles. It features a polyester dielectric with a capacitance of 0.5 µF and a DC voltage rating of 600 VDC. The unit incorporates an internal resistance of 22 Ohms to suppress electrical arcing and noise. Designed for surface mounting via straight leads, it operates within a temperature range of -55°C to +85°C. The component measures 36.8 mm in length, 15 mm in width, and 23.4 mm in height, with a standard lead spacing of 30.5 mm.
Feature Summary
- Integrated RC snubber network designed to reduce or eliminate electrical arcing, noise, and electromagnetic interference (EMF).
- Utilizes polyester film dielectric for stable performance in high-voltage switching applications.
- Radial leaded construction facilitates through-hole mounting on printed circuit boards.
Applications
- Arc suppression in motor control circuits
- Snubber networks for power electronic switches
- EMI/RFI filtering in industrial equipment
Procurement Notes
Verify the specific internal resistance value against design requirements, as the QAS series includes variants with different resistance values such as 22 Ohms and 47 Ohms. Confirm that the radial lead spacing and physical dimensions align with the target PCB footprint. Ensure the 600 VDC rating provides adequate margin for the operating environment. Check RoHS compliance status if required by project specifications.
Selection Notes
Select this component when a combined capacitor and resistor solution is needed for transient suppression. The integrated design saves board space compared to discrete components. Consider the thermal dissipation capabilities of the 22 Ohm resistor under continuous operation. Verify that the polyester dielectric meets the frequency and voltage stress requirements of the application.
Part Context
The QAS series represents Cornell Dubilier Knowles' specialized line of arc suppressor and snubber networks. These components are engineered to protect sensitive electronics from voltage spikes and contact bounce. The series offers various capacitance and resistance combinations to suit diverse circuit protection needs.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult manufacturer catalogs for direct equivalents or verify compatibility with other QAS series variants based on electrical parameters.
