Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact packaging and terminal specifications. Confirm RoHS compliance status directly with the supplier as regulatory data may vary by production batch. Ensure the requested quantity aligns with the manufacturer's standard reel or bulk packaging requirements before finalizing the purchase order.

Selection Notes

Select this component when an unshielded RF inductor with 560 nH inductance is required for space-constrained PCB layouts. The 2.54 x 2.54 mm footprint allows for dense mounting. Consider the 590 mA current rating and 278 mOhm resistance for power handling needs. Verify that the 175 MHz self-resonant frequency meets the operational bandwidth requirements of the target circuit design.

Part Context

This part belongs to the 103/R series of fixed RF inductors manufactured by Delevan. The series provides various inductance values within a consistent surface-mount form factor. These components are designed specifically for radio frequency applications requiring stable inductance characteristics in compact electronic assemblies.

Replacement Considerations

The 103-561HS is listed as an alternative designation for this component type. Verify pinout compatibility and electrical parameter equivalence before substitution.
