Fixed Inductors Procurement Notes

Verify that the suffix RC confirms RoHS compliance and halogen-free status as per manufacturer specifications. Confirm the axial package dimensions match the target PCB layout requirements. Ensure the 78 mA current rating meets the operational load conditions to prevent saturation or thermal issues during procurement validation.

Fixed Inductors Selection Notes

Select this component when a fixed 1 mH inductance is required for RF applications with limited space due to its axial form factor. Consider the 78 mA current limit and 16.5 Ohm DC resistance for circuit impedance matching. The 2.8 MHz self-resonant frequency defines the upper operational limit for effective choking behavior in the intended frequency range.

Fixed Inductors Part Context

This part belongs to the Bourns 9220 series of molded axial inductors. These components are designed for general-purpose electronic circuits requiring reliable RF filtering. The series utilizes wirewound techniques on ferrite cores to achieve consistent electrical characteristics across production batches.

Fixed Inductors Replacement Considerations

Cross-reference with other 1 mH axial wirewound inductors from different manufacturers if supply constraints exist. Verify that substitute parts maintain equivalent current ratings, DC resistance, and self-resonant frequencies to ensure circuit compatibility without redesign.
