QAS504K600D047

Overview

The QAS504K600D047 is a radial leaded snubber film capacitor manufactured by Cornell Dubilier Knowles. It utilizes polyester dielectric and features an integrated resistance of 47 Ohms for RC snubber applications. The component supports a DC voltage rating of 600 VDC and an AC voltage rating of 250 VAC, with a capacitance value of 0.5 uF and a tolerance of 10%. 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. It operates within a temperature range of -55°C to +85°C.

Feature Summary

• Integrated 47 Ohm resistance designed specifically for RC snubber networks
• Polyester dielectric construction for reliable transient suppression
• Radial leaded termination for through-hole mounting

Applications

• RC Snubber Networks
• EMI Filtering
• Transient Suppression

Procurement Notes

Verify the specific manufacturer designation, as sources list both Knowles / Illinois Capacitor and Cornell Dubilier. Confirm RoHS compliance status directly from the official datasheet before integration. Ensure the 47 Ohm internal resistance matches the circuit requirements, as this is a fixed parameter of the QAS series.

Selection Notes

Select this component when an integrated RC snubber solution is required for high-voltage transient suppression. The 600 VDC rating and 47 Ohm resistance are fixed characteristics. Verify that the radial package dimensions and 30.5 mm lead spacing fit the PCB layout constraints compared to axial alternatives.

Part Context

This part belongs to the QAS series of snubber film capacitors. It combines a 0.5 uF polyester capacitor with a 47 Ohm resistor in a single radial package. The series is engineered for EMI filtering and arc suppression, offering a compact alternative to discrete RC components in power electronics.
