Fixed Inductors Procurement Notes

Verify the specific suffix (M or K) during procurement, as it denotes tolerance differences. Confirm that the requested part matches the exact inductance value and current ratings required by the circuit design. Ensure compatibility with standard surface-mount assembly processes. Check for any recent product change notices regarding availability or manufacturing updates.

Fixed Inductors Selection Notes

Select this component when a 68 µH inductance is required in a 1007 package size. Consider the low saturation current of 70 mA for applications with significant DC bias. Compare against shielded alternatives if electromagnetic interference mitigation is critical. Evaluate thermal management requirements given the operating temperature limits.
