810912003

Overview

The Würth Elektronik WE-CLFS 810912003 is a single-phase power line filter designed for EMI/EMI suppression. It features a rated current of 3 A and a voltage rating of 250 VAC, operating at 50/60 Hz. The component has a DC resistance (DCR) of 100 mΩ and an inductance of 10 mH. Physical dimensions are 75 mm length, 51.8 mm width, and 29 mm height. It utilizes Faston quick-connect terminals and supports chassis mounting.

Feature Summary

• Single-stage EMC/EMI filtering architecture
• Faston quick-connect terminal interface
• Chassis mount installation style

Applications

• Industrial equipment power input stages
• Medical device power supplies
• Consumer electronics AC mains filtering

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm exact electrical tolerances and terminal configurations. Ensure the ordering code matches the required current rating and physical footprint. Cross-reference certification marks such as UL or IEC if regulatory compliance is mandatory for the end application.

Selection Notes

Select this component when a single-stage solution is sufficient for noise attenuation requirements. The 3 A rating suits moderate power applications. Verify that the 100 mΩ DCR meets system efficiency constraints. Confirm that the chassis mount form factor fits the available enclosure space and thermal management strategy.

Part Context

This part belongs to the WE-CLFS series from Würth Elektronik, which specializes in single-phase power line filters. The series offers various current ratings and inductance values to address different EMI suppression needs across industrial and commercial sectors.

Replacement Considerations

Check for direct substitutes with identical 3 A ratings and 10 mH inductance. Verify pinout compatibility for Faston terminals. Ensure replacement parts meet the same safety certifications and dimensional constraints.
