Fixed Inductors Procurement Notes

Verify the specific ordering suffix to confirm tolerance code accuracy, as K denotes ±10% tolerance. Ensure compliance with RoHS requirements if applicable, noting that some series variants may differ in environmental certification status. Confirm lead type and mounting style match the target PCB layout constraints before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a shielded axial inductor with 180 µH nominal value is required. Consider the 135 mA current rating and 4.4 Ω DC resistance against circuit load requirements. Evaluate the 8 MHz self-resonant frequency to ensure suitability for the intended signal frequencies. Verify package dimensions fit available board space.
