Procurement Notes

Verify availability status as distribution may be limited. Confirm RoHS compliance details directly with the manufacturer or authorized distributors before procurement. Ensure the specific package dimensions and lead configurations match the target PCB layout requirements for proper installation.

Selection Notes

Select this component when a 4.5 mH inductance value is required for common mode rejection. Ensure the circuit design accommodates the 3.7 A current rating and the 20 mOhm DC resistance to minimize voltage drop. Verify that the operating environment stays within the specified -40°C to +125°C temperature range.

Part Context

This part belongs to the ALFT series of common mode chokes manufactured by Abracon LLC. The series offers various inductance and current ratings tailored for different filtering needs. The ALFT-04-7 specifically targets applications requiring moderate inductance with significant current handling capabilities in a through-hole package.

Replacement Considerations

Consult official datasheets for direct substitutes within the ALFT series. Verify that any replacement matches the 4.5 mH inductance, 3.7 A current rating, and 20 mOhm DCR specifications. Ensure physical footprint compatibility for through-hole mounting.
