Overview
The 254M06QD47 is a Quencharc RC Snubber Film Capacitor manufactured by Cornell Dubilier Knowles. It features a polyester dielectric with a capacitance of 0.25 uF and an integrated series resistance of 47 Ohms. The component supports a DC voltage rating of 600 VDC and an AC voltage rating of 250 VAC, with a tolerance of ±10%. Designed for radial through-hole mounting, it measures 36.8 mm in length, 10.6 mm in width, and 19 mm in height. The unit operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a 47 Ohm resistor directly with the capacitor element to form a single RC snubber unit.
- Utilizes polyester film dielectric technology for stable electrical performance.
- Engineered specifically for high-voltage switching applications requiring EMI suppression.
Applications
- RC Snubber circuits
- EMI/RFI filtering
- Power electronics protection
Procurement Notes
Verify the specific part number against official manufacturer documentation to ensure accuracy. Confirm that the required capacitance, resistance value, and voltage ratings align with the circuit design specifications. Check for RoHS compliance requirements if applicable to the target assembly. Ensure the radial lead spacing matches the PCB layout constraints before finalizing procurement decisions.
Selection Notes
Select this component when a combined RC snubber solution is required for high-voltage environments. The 47 Ohm resistance and 0.25 uF capacitance are fixed parameters; verify they match the damping requirements of the application. Consider the 600 VDC rating for safety margins in industrial power systems. The radial package dictates specific board space and mounting orientation constraints.
Part Context
This component belongs to the Quencharc Q/QRL series of film capacitors from Cornell Dubilier Knowles. The series is designed for robust performance in demanding power electronic applications. These units combine passive components into a single housing to simplify assembly and improve reliability in noise-sensitive circuits.
Replacement Considerations
Consult official manufacturer substitution guides for verified alternatives. Ensure any replacement maintains the same 47 Ohm resistance and 0.25 uF capacitance values. Verify compatibility with existing voltage ratings and physical dimensions to prevent installation issues.
