CIH05QR12JNC

Fixed Inductors Overview

The Samsung Electro-Mechanics CIH05QR12JNC is an unshielded multilayer inductor designed for surface-mount applications. It provides a nominal inductance of 120 nH with a tolerance of ±5%. The component features a maximum DC resistance of 2 Ohms and supports a current rating of 150 mA. It is housed in a compact 0402 (1005 Metric) package, measuring 1.00mm x 0.50mm. This configuration ensures suitability for high-frequency RF and analog circuit implementations where precise inductive values are required.

Fixed Inductors Feature Summary

• Unshielded multilayer construction for high-frequency signal processing
• Precision inductance tolerance for stable analog performance
• Compact 0402 surface-mount footprint for space-constrained designs

Fixed Inductors Applications

• High-frequency RF circuits
• Analog signal conditioning
• General-purpose surface-mount electronics

Fixed Inductors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure the correct variant is procured. Confirm that the unshielded design aligns with the electromagnetic interference requirements of the target application. Cross-reference the 150 mA current rating and 2 Ohm resistance limits with the system's operational parameters to prevent performance degradation or thermal issues during deployment.

Fixed Inductors Selection Notes

Select this component when a small form factor is critical for the layout. The unshielded nature requires careful placement to avoid coupling with nearby sensitive traces. Ensure the operating environment does not exceed the thermal limits associated with the 150 mA rating. Consider the ±5% tolerance if tighter precision is needed for the specific frequency response of the circuit.

Fixed Inductors Part Context

This part belongs to the CIH05Q series of fixed single-surface mount inductors from Samsung Electro-Mechanics. The manufacturer specializes in passive components, including MLCCs and power inductors, serving global electronics markets.
