Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Samsung Electro-Mechanics documentation to ensure accuracy. Confirm that the component meets all required electrical specifications for your design, including inductance, DCR, and current ratings. Check for any recent product change notices or end-of-life announcements associated with this part number before finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component when a small 0402 footprint is required for high-frequency applications. Ensure the 250 mA current rating and 900 mΩ DCR are sufficient for the target circuit. Consider the unshielded nature of the device regarding potential electromagnetic interference in dense layouts compared to shielded alternatives.

Fixed Inductors Part Context

This inductor belongs to the CIH series of chip inductors from Samsung Electro-Mechanics. These components are generally used in consumer electronics and communication equipment where space constraints are critical. The CIH series offers various inductance values and package sizes to support diverse design requirements.

Fixed Inductors Replacement Considerations

The CIH05T27NJNC is functionally similar to the CIH05T27NJKC, which shares the same 0402 package and 27 nH inductance but may have different tolerance or current characteristics. Verify compatibility with existing PCB footprints and electrical parameters before substitution.
