Fixed Inductors Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct packaging configuration, such as tape-and-reel versus cut-tape options. Confirm that the selected variant matches the required electrical tolerances and thermal ratings for the target application environment. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a compact 0805 form factor is required for unshielded inductive applications. Ensure the 400 mA current rating aligns with the maximum operational load to prevent saturation. Verify that the 120 nH inductance value meets the specific impedance requirements of the circuit design. Consider the 510 mOhm DC resistance impact on overall system efficiency during selection.
