Fixed Inductors Procurement Notes

Verify the specific suffix 'RC' against the manufacturer's current nomenclature standards to confirm compliance status and packaging format. Ensure the ordering code matches the exact inductance value of 0.12 µH and tolerance requirements. Cross-reference the lead style and terminal count with schematic specifications before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when an unshielded axial inductor with low inductance is required for general purpose or RF applications. Consider the 0.06 Ω DC resistance and 1.2 A current handling capability if present in related datasheets. Evaluate the thermal operating range of -55 °C to +105 °C against environmental constraints. Compare physical footprint dimensions against available PCB space.

Fixed Inductors Part Context

This part belongs to the Bourns 78F series of fixed inductors, which are characterized by their wirewound construction on bobbin cores. The series offers various inductance values and tolerances for different electronic needs. The 78FR12M-RC specifically targets applications requiring small form factor inductance with axial leads.

Fixed Inductors Replacement Considerations

Direct substitutes may include other 0.12 µH axial inductors from manufacturers such as Coilcraft or Pulse Electronics, provided they match the 0.06 Ω DC resistance and physical dimensions. Verify that alternative parts meet the same -55 °C to +105 °C operating temperature range and ferrite core material properties.
