Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct inductance and tolerance specifications. Confirm that the component status aligns with project requirements, as availability may vary. Ensure compatibility with standard reflow soldering profiles for 0402 packages. Cross-reference the RoHS compliance status with current regulatory standards for the target market.

Fixed Inductors Selection Notes

Select this component for applications requiring ultra-low inductance values in minimal footprint designs. The unshielded nature requires careful PCB layout to prevent crosstalk in dense high-frequency circuits. Evaluate the 750 mA current rating against peak load conditions to avoid saturation. Consider the 10 GHz self-resonant frequency limit when designing for signals approaching microwave frequencies.

Fixed Inductors Part Context

This part belongs to the 0402HM series of fixed inductors, designed for high-frequency RF and microwave applications. The series utilizes ceramic materials for the drum core to maintain stability. Similar parts in the series offer varying inductance values while maintaining the same 0402 form factor and general electrical characteristics.

Fixed Inductors Replacement Considerations

Direct substitutes include other 0.4mm height 0402 unshielded inductors with 3.9nH nominal value. Verify equivalent DCR and Q-factor specifications. Check for pin-out compatibility if alternative manufacturers are considered.
