Procurement Notes

Verify the specific suffix 'JS' against official manufacturer documentation to confirm terminal plating and packaging specifications. Ensure compatibility with standard SMT reflow processes. Cross-reference the exact part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status through current datasheets before integration into regulated products.

Selection Notes

Select this component when a 3.3 µH inductance value is required for RF applications. Consider the 260 mA current rating and 1.4 Ohm DC resistance for power loss calculations. The unshielded design may require careful layout to prevent crosstalk. Verify that the 70 MHz self-resonant frequency aligns with the target operating frequency range.

Part Context

This part belongs to the 103/R series of RF inductors manufactured by API Delevan. The series offers various inductance values optimized for radio frequency environments. The 103R-332JS specifically provides a mid-range inductance value suitable for intermediate frequency stages or filtering applications within RF transceivers.

Replacement Considerations

Direct substitutes include the 103-332F and 103-332JS from Delevan, which share identical electrical parameters and form factors. Verify pinout and dimensional tolerances before substitution.
