• Offline switching power supplies

Procurement Notes

Verify the specific package variant and lead times directly with authorized distributors or the manufacturer. Confirm RoHS compliance status and ensure the ordering code matches the required tape-and-reel or cut-tape configuration for your assembly process.

Selection Notes

Select this component when a high-current common mode choke with low DC resistance is required for space-constrained designs. The 1 mH inductance provides effective noise attenuation for mains-powered circuits while maintaining a compact footprint suitable for modern PCB layouts.

Part Context

This part belongs to the WE-LF SMD series, which offers shielded common mode chokes designed for mains power lines. The series is characterized by its robust ferrite core and wirewound construction, providing reliable performance in industrial and consumer electronics environments requiring strict EMI standards.

Replacement Considerations

Check for direct substitutes within the WE-LF series with similar inductance and current ratings. Verify pin compatibility and mechanical dimensions before replacing to ensure fitment on existing footprints.
