Fixed Inductors Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before integration, as distributor listings may contain conflicting values. Confirm that the axial lead configuration matches the target PCB layout requirements. Ensure the operating environment stays within the specified temperature limits for reliable performance.

Fixed Inductors Selection Notes

Select this component when an 18 µH inductance value is required for RF circuits. The unshielded nature necessitates careful placement to minimize electromagnetic interference with nearby traces. Verify that the 31 Ohm DC resistance is acceptable for the current handling requirements of the specific application circuit.

Fixed Inductors Part Context

This part belongs to the ER1537 series of fixed inductors manufactured by Delevan.
