Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm exact electrical tolerances and packaging options. Ensure compatibility with automated pick-and-place equipment regarding the specified height and terminal type. Confirm RoHS compliance status through official certificates if required by regulatory standards.

Selection Notes

Select this component when low inductance and high impedance at high frequencies are required for EMI suppression. The 300 mA rating suits low-power signal lines or auxiliary power rails. Compare impedance curves against target noise frequencies to ensure adequate attenuation performance.

Part Context

This part belongs to the WE-SLM series of small-size common mode chokes. The series is characterized by its compact form factor and suitability for high-frequency applications. It complements other WE-SLM variants offering different inductance and current ratings.

Replacement Considerations

Check for direct substitutes within the WE-SLM series with matching impedance and current ratings. Verify pinout and mechanical dimensions before replacing to ensure board compatibility.
