Procurement Notes

Verify the exact part number suffix to confirm tolerance and resistance specifications, as variations exist within the series. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the ordering quantity aligns with the manufacturer's reel packaging requirements to avoid handling discrepancies during production integration.

Selection Notes

Select this component when an unshielded inductor is required for RF applications to minimize magnetic interference with adjacent components. Consider the 340 mA current rating and 0.84 Ω DC resistance to ensure compatibility with the target circuit's power budget. The 115 MHz self-resonant frequency defines the upper operational limit for effective inductance.

Part Context

This component belongs to the 103/R series of fixed inductors manufactured by API Delevan. The series offers various inductance values and tolerance options tailored for general-purpose and RF electronic applications. The 103R-152JS specifically addresses needs for low-inductance, high-frequency surface-mount implementations.

Replacement Considerations

Direct substitutes include other 1.5 µH SMD inductors with similar current ratings and unshielded designs. Verify that alternative parts match the 2.54 x 2.54 mm footprint and 1.91 mm height constraints. Cross-reference DC resistance and Q factor values to ensure equivalent electrical performance in the target application.
