Fixed Inductors Procurement Notes

Verify the exact inductance value and tolerance against the manufacturer's official datasheet before integration. Confirm that the 540 mA current rating meets the specific circuit requirements. Ensure the unshielded design does not cause interference in dense layouts. Check RoHS compliance status via the supplier documentation.

Fixed Inductors Selection Notes

Select this component when an unshielded wirewound inductor is required for frequencies where self-resonance characteristics are critical. The 0402 package suits space-constrained designs. Consider the 140 mOhms DCR impact on power efficiency. Compare against shielded alternatives if EMI mitigation is necessary for the application environment.

Fixed Inductors Part Context

This part belongs to the WLCW series of unshielded drum core inductors manufactured by Walsin Technology Corporation. These components are designed for high-frequency applications requiring precise inductance values in small form factors. The series offers various inductance options within the 0402 package.

Fixed Inductors Replacement Considerations

Direct substitutes include other Walsin WLCW series parts with similar inductance and current ratings. Cross-manufacturer replacements must match the 7.1 nH value, 540 mA rating, and 0402 dimensions. Verify that alternative unshielded types maintain comparable Q-factor and self-resonant frequency performance.
