810912020

Overview

The Würth Elektronik WE-CLFS series component, part number 810912020, is a single-phase power line filter designed for chassis mounting. It features a rated voltage of 250 VAC and supports operating frequencies of 50 Hz and 60 Hz. The unit has a current rating of 20 A and utilizes screw termination for secure electrical connections. Certified under UL, CSA, and IEC/EN standards, this filter ensures compliance with international safety regulations.

Feature Summary

• Provides electromagnetic interference suppression for single-phase AC power lines
• Designed for robust chassis mounting applications
• Complies with major international safety certification standards

Applications

• Industrial equipment power supply filtering
• Machinery control panel noise reduction
• Consumer appliance EMI mitigation

Procurement Notes

Verify the specific current rating against project requirements, as datasheets indicate variations within the WE-CLFS series. Confirm that the chassis mount style and screw termination align with the enclosure design. Ensure the 250 VAC rating matches the local mains voltage specifications to guarantee safe operation and regulatory compliance.

Selection Notes

Select this model when high current capacity up to 20 A is required for single-phase filtering. Compare against lower-rated variants in the same series if load currents are minimal. Consider the physical dimensions and chassis mounting constraints during the mechanical design phase to ensure proper fitment within the target equipment housing.

Part Context

This component belongs to the WE-CLFS family of power line filters manufactured by Würth Elektronik. These components are engineered to attenuate conducted electromagnetic interference on AC mains inputs. The series offers various current ratings to suit different power levels while maintaining consistent form factors and mounting styles for standardized integration.

Replacement Considerations

Cross-reference with part number 810912001112 for similar WE-CLFS specifications. Verify that substitute models match the 20 A current rating and 250 VAC voltage limit. Ensure the replacement maintains the same chassis mount configuration and screw termination type for direct compatibility.
