Overview
The QAS504K600D150 is a polyester film RC snubber network manufactured by Cornell Dubilier Knowles. It integrates a 0.5 µF capacitor with a 150 Ohm resistor in a single radial component. The unit supports a DC voltage rating of 600 VDC and an AC voltage rating of 250 VAC. Key physical dimensions include a length of 36.8 mm, width of 15 mm, and height of 23.4 mm, with a lead spacing of 30.5 mm. The device operates within a temperature range of -55°C to +85°C.
Feature Summary
- Integrates RC snubber functionality for electrical arcing suppression
- Designed to reduce electromagnetic interference (EMI) and noise
- Utilizes metallized polyester dielectric for stable performance
Applications
- Arc suppression in switching circuits
- Noise reduction in industrial power electronics
- Electromagnetic interference filtering
Procurement Notes
Verify the specific resistance value of 150 Ohms against circuit requirements, as the QAS series includes variants with different resistances such as 47 Ohms or 100 Ohms. Confirm that the 600 VDC rating aligns with the system's peak voltage stresses. Ensure the radial lead spacing of 30.5 mm fits the target PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a combined snubber and filter solution is required for high-voltage applications. The integrated design simplifies assembly compared to discrete components. Consider the operating temperature limit of +85°C and ensure the application environment remains within this range to maintain reliability and prevent premature degradation of the polyester dielectric.
Part Context
This part belongs to the QAS series of arc suppressor and snubber networks from Cornell Dubilier Knowles. These components are engineered to mitigate electrical arcing and associated noise in industrial and automotive environments. The series provides a compact alternative to discrete RC networks, offering consistent performance characteristics for EMI suppression tasks.
Replacement Considerations
Direct substitutes must match the 0.5 µF capacitance, 150 Ohm resistance, and 600 VDC rating. Variants like QAS504K600D047 differ significantly due to their 47 Ohm resistance. Verify pin compatibility and thermal ratings when considering cross-brand alternatives.
