Procurement Notes

Verify the specific manufacturer designation, as the part number appears under both API Delevan and Delevan branding across different distributors. Confirm the lifecycle status, as some sources indicate this model may be obsolete. Ensure compatibility with standard SMD reflow processes and validate that the 555 mA current rating meets the target application requirements before procurement.

Selection Notes

Select this component when an unshielded inductor is required to minimize parasitic coupling effects in sensitive RF layouts. The 105 series offers a compact footprint suitable for space-constrained designs. Engineers should verify that the 215 MHz self-resonant frequency aligns with the operating bandwidth of the intended circuit to ensure proper impedance characteristics.

Part Context

This component belongs to the Delevan 105 series of surface-mount RF inductors. The series provides various inductance values optimized for radio frequency applications. The 105-471J specifically utilizes an unshielded wire-wound or foil construction typical of this family, distinguishing it from shielded alternatives like the S1812R series.
