Fixed Inductors Procurement Notes

Verify the manufacturer part number 78F100J-RC against official Bourns documentation to confirm specifications. Ensure the required inductance value of 10 µH and current rating of 370 mA align with circuit requirements. Check for availability of the specific leaded package type and confirm compliance with relevant industry standards before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when an unshielded axial RF inductor with 10 µH nominal inductance is required. Consider the 370 mA current rating and 750 mOhm resistance limits for power handling. The conformal coating offers environmental protection. Verify that the unshielded design does not interfere with nearby sensitive components due to potential magnetic field radiation.

Fixed Inductors Part Context

This part belongs to the Bourns 78F Series of RF chokes. It is manufactured by Bourns Inc., which acquired assets from J.W. Miller Magnetics. The series includes various inductance values within the same physical form factor, such as the 78F8R2J-RC variant. These components are characterized by their leaded, conformal-coated construction suitable for through-hole mounting.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include other 78F model variants with different inductance values, such as 78F8R2J-RC. Cross-referencing with similar unshielded drum core inductors from other manufacturers requires matching the 10 µH inductance, 370 mA current rating, and axial lead dimensions.
