Procurement Notes

Verify the specific manufacturer part number against official Delevan documentation to ensure compatibility with design requirements. Confirm RoHS compliance status through the latest datasheet or product change notifications. Check for any recent supply chain updates or alternative packaging options directly from authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when high inductance accuracy is critical for RF performance. The unshielded design requires careful layout consideration to minimize electromagnetic interference with nearby traces. Ensure the operating current remains below the 340 mA rating to maintain thermal stability and inductance integrity within the specified temperature range.

Part Context

This component belongs to the 103/R series of RF inductors manufactured by Delevan. The series offers various inductance values optimized for radio frequency applications. The 103R-152FS specifically provides a 1.5 µH value with tight tolerances, distinguishing it from lower-precision variants in the same family.

Replacement Considerations

Direct substitutes include other 1.5 µH ±1% SMD RF inductors with similar current ratings and dimensions. Verify that alternative components meet the 115 MHz self-resonant frequency requirement and match the 2.54 x 2.54 mm footprint constraints.
