Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with RoHS directives if required by the target application environment. Cross-reference datasheet revisions to validate current manufacturing status and parameter consistency before finalizing procurement specifications.

Selection Notes

Select this component when a compact SMD form factor is required for RF applications operating at 0.82 µH. The phenolic core offers distinct characteristics compared to ferrite or iron alternatives. Evaluate the 0.53 Ω DC resistance against power loss constraints and ensure the 1008 footprint fits the available board space without compromising thermal management requirements.

Part Context

This part belongs to the 103/R series of fixed RF inductors manufactured by Delevan. The series provides various inductance values in standardized SMD packages designed for high-frequency electronic circuits. These components are engineered for reliability in demanding RF environments where consistent inductance and low parasitic effects are critical for system performance.

Replacement Considerations

Direct substitutes include the ER103R-821JS from Delevan. Verify mechanical dimensions and electrical parameters against original specifications before implementation.
