Fixed Inductors Procurement Notes

Verify part availability status carefully as this specific model may be discontinued or subject to production changes. Confirm that the ordering suffix matches the required packaging format and RoHS compliance standards. Cross-reference the manufacturer's latest product change notifications to ensure the component meets current environmental regulations and supply chain requirements before finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component when space constraints require an 0402 footprint with low inductance values. Ensure the application current does not exceed the 300 mA rating to prevent saturation. Verify that the self-resonant frequency aligns with the target operating bandwidth. Consider the unshielded nature of the device regarding potential electromagnetic interference in dense layouts.

Fixed Inductors Part Context

This inductor belongs to Samsung Electro-Mechanics' CIH series, which focuses on small-form-factor passive components. The series utilizes advanced multilayer technology to achieve high reliability in miniature packages. These components are designed for modern electronics requiring miniaturization without compromising electrical performance in RF and power management applications.

Fixed Inductors Replacement Considerations

Check official substitution lists for equivalent inductance and package dimensions. Verify that any alternative maintains the same Q factor and self-resonant frequency specifications. Ensure thermal and current ratings match or exceed original requirements.
