Procurement Notes

Verify the specific manufacturer part number against official Delevan documentation to ensure compatibility with design requirements. Confirm that the unshielded package style aligns with PCB layout constraints. Check RoHS compliance status if required by project specifications. Ensure the operating temperature range meets environmental conditions.

Selection Notes

Select this component for applications requiring low inductance values in the nanohenry range. Consider the 1.27 A current rating for power handling needs. The 2.54 x 2.54 mm footprint must fit within available board space. Verify that the unshielded nature does not cause coupling issues with nearby components.

Part Context

This part belongs to the 103R series of fixed RF inductors from Delevan. These components are designed for surface-mount technology (SMT) assembly. The series offers various inductance values tailored for radio frequency circuitry. The 103R-100MS specifically targets high-frequency signal processing tasks.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Ensure replacement parts match the 10 nH inductance, 1.27 A current rating, and 2.54 x 2.54 mm footprint. Verify identical shielding characteristics and temperature ratings.
