Fixed Inductors Procurement Notes

Verify the specific suffix 'F' against official manufacturer documentation to confirm tolerance and material specifications. Ensure compatibility with RoHS directives if required by the target application. Cross-reference datasheets for thermal derating curves and mechanical dimensions prior to integration into final assembly designs.

Fixed Inductors Selection Notes

Select this component when a 2.2 µH inductance with 1% precision is required for axial mounting. Consider the 485 mA current rating and 0.95 Ω DC resistance for power handling capabilities. Evaluate the 135 MHz self-resonant frequency to ensure suitability for the intended operating bandwidth.
