Procurement Notes

Verify the specific manufacturer part number against official Delevan documentation to ensure compatibility with your circuit requirements. Confirm that the unshielded configuration and electrical parameters align with your design specifications before finalizing procurement decisions.

Selection Notes

Select this component when an unshielded RF inductor with 15 µH nominal value is required. Ensure the 135 mA current rating and 5.6 ohm DC resistance meet the circuit constraints. Verify that the 2.54 x 2.54 mm footprint fits the available PCB space.

Part Context

This component belongs to the 103/R series of fixed inductors manufactured by Delevan. It is categorized as an RF inductor designed for surface-mount technology. The series provides standard non-standard lead configurations suitable for general RF signal processing tasks.

Replacement Considerations

Consider the 103R-153K for identical electrical characteristics with a 10% tolerance instead of 5%. Other series such as 1210R or MIL1812R offer different form factors but may not match the exact footprint or shielding requirements.
