810912012

Overview

The Würth Elektronik WE-CLFS 810912012 is a single-phase power line filter designed for chassis mounting. It operates at voltage ratings of 250 VAC and frequencies of 50 Hz or 60 Hz, with a current rating of 12 A. The component features Fast-On blade terminals measuring 6.3 x 0.8 mm for connection. Electrical specifications include an inductance of 2.2 mH and a DC resistance (DCR) of 20 mΩ. The unit provides broadband noise suppression in both common and differential modes to ensure electromagnetic compatibility.

Feature Summary

• Provides broadband noise suppression in common and differential modes
• Designed for easy installation using Fast-On blade terminals
• Constructed for robust chassis mounting applications

Applications

• Industrial equipment requiring EMI/RFI filtering
• Power supply input stages for single-phase AC systems
• Electromagnetic compatibility enhancement in electronic enclosures

Procurement Notes

Verify the specific terminal dimensions and mounting hole patterns against your mechanical design requirements before procurement. Confirm that the 12 A current rating and 250 VAC voltage rating align with your system's operational parameters. Ensure the chassis mounting style is compatible with your enclosure structure. Cross-reference the datasheet for thermal derating curves if operating near maximum limits.

Selection Notes

Select this component when a single-phase solution with high current capacity is required. The 12 A rating distinguishes it from lower-current variants in the WE-CLFS series. Consider the 20 mΩ DCR for potential power loss calculations. The Fast-On terminal type simplifies wiring compared to screw-terminal alternatives. Evaluate the physical footprint to ensure it fits within the designated chassis space.

Part Context

This part belongs to the WE-CLFS Advanced Single-Phase Line Filter family from Würth Elektronik. These filters are engineered for effective attenuation of conducted electromagnetic interference. The series offers various current ratings and inductance values to suit different power levels. The 810912012 specifically targets higher current applications within this lineup.

Replacement Considerations

Direct substitutes may include other parts from the WE-CLFS series with similar electrical characteristics. Verify compatibility by comparing current ratings, inductance values, and terminal types. Alternative manufacturers may offer comparable single-phase filters, but mechanical fit and certification compliance must be validated.
