QAS104K200D150

Overview

The QAS104K200D150 is a first-order RC snubber network manufactured by Cornell Dubilier Knowles. It features a radial package with integrated components: a 0.1µF capacitor and a 150Ω resistor. Designed as an EMI filter, this unit combines filtering elements into a single component to simplify circuit assembly. The device operates within standard industrial temperature ranges and provides reliable suppression of electrical noise and voltage transients in power electronics applications.

Feature Summary

• Integrates a 0.1µF capacitor and 150Ω resistor into a single radial component for simplified mounting
• Functions as a first-order RC snubber network to suppress electrical arcing and electromagnetic interference
• Designed to reduce or eliminate EMF and noise in switching circuits

Applications

• Arc suppression in contactors and relays
• Snubber networks for motor drives
• EMI/RFI filtering in power supplies

Procurement Notes

Verify the specific part number QAS104K200D150 against official Cornell Dubilier Knowles documentation to confirm the integrated resistance value of 150 Ohms and capacitance of 0.1µF. Ensure the radial lead configuration matches the target PCB layout. Confirm that the component meets the required environmental ratings for the intended operating conditions before finalizing procurement.

Selection Notes

Select this component when a compact, pre-tuned RC snubber solution is required for transient suppression. The integrated design eliminates the need for separate discrete components, saving board space and assembly time. Verify that the 150Ω resistance and 0.1µF capacitance values align with the specific circuit impedance and frequency requirements for effective arc suppression.

Part Context

The QAS series represents Cornell Dubilier Knowles' dedicated line of arc suppressor and snubber networks. These components are engineered to replace multiple discrete parts, offering a robust solution for managing voltage spikes and electromagnetic interference in industrial and automotive environments. The series focuses on reliability and ease of integration for high-noise applications.

Replacement Considerations

Direct replacement requires verifying identical electrical parameters: 0.1µF capacitance and 150Ω resistance. Ensure the radial package dimensions and lead spacing match the existing footprint. Cross-reference with other manufacturers' RC snubber modules if availability is constrained, confirming equivalent voltage ratings and thermal performance.
