Fixed Inductors Procurement Notes

Verify the specific date code suffix to confirm RoHS compliance status, as indicated by the 'R' prefix in manufacturer documentation. Ensure the axial lead configuration matches the target PCB layout requirements. Cross-reference the 2% tolerance specification against circuit sensitivity needs to guarantee performance stability under varying thermal conditions.

Fixed Inductors Selection Notes

Select this component when a precise 27 µH inductance value is required with tight 2% tolerance constraints. The 140 mA current rating dictates suitability for low-power signal paths rather than high-current power stages. Consider the 3.5 Ohm DC resistance impact on voltage drop within the specific circuit topology before integration.

Fixed Inductors Part Context

This part belongs to the 1025R series of fixed inductors manufactured by API Delevan. The series offers various inductance values ranging from nanohenries to microhenries, all sharing similar unshielded molded axial packages. This specific model represents a mid-range inductance option within that product family.

Fixed Inductors Replacement Considerations

Direct substitutes include other 27 µH axial inductors with comparable 140 mA ratings and 3.5 Ohm max resistance. Verify physical lead spacing compatibility. Alternative manufacturers may offer shielded variants if EMI mitigation becomes necessary, though electrical parameters must remain equivalent.
