Fixed Inductors Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance for this specific part number. Confirm manufacturing origin and lot traceability requirements against project specifications. Ensure supply chain sources provide valid manufacturer certificates of conformity. Check for any export control classifications or restricted material declarations relevant to the procurement region. Validate that the supplier offers genuine Delevan components to guarantee specified electrical parameters.

Fixed Inductors Selection Notes

Select this component when precise 27 uH inductance with 1% tolerance is required for RF signal paths. The axial package suits manual assembly or wave soldering processes. Consider the 140 mA current rating and 3.5 Ohm DCR for power handling constraints. Evaluate the 20 MHz self-resonant frequency to ensure operation remains below parasitic resonance limits. Compare against other 1025R series variants if different inductance values or tolerances better fit the design goals.

Fixed Inductors Part Context

This part belongs to the Delevan 1025/R series of fixed RF inductors. The series utilizes molded technology to provide consistent electrical performance across production batches. Components are designed for robustness in demanding electronic environments. The axial form factor allows for secure mechanical attachment on printed circuit boards.
