CIG21F1R0MNC

Fixed Inductors Overview

The CIG21F1R0MNC is a fixed surface-mount power inductor manufactured by Samsung Electro-Mechanics. It features a metal composite core and shielded construction, designed for high-current applications. The component has an inductance of 1 µH with a tolerance of ±20%. It supports a maximum current rating of 800 mA and exhibits a DC resistance of 190 mΩ. The device operates within a temperature range of -40°C to 125°C and is housed in a compact 0806 (2016 metric) package.

Fixed Inductors Feature Summary

• Shielded metal composite core design minimizes electromagnetic interference
• Optimized for high-current power supply circuits
• Compact surface-mount footprint for space-constrained layouts

Fixed Inductors Applications

• DC-DC converter output filtering
• Power management integrated circuit (PMIC) input/output stages
• Portable electronic device power supplies

Fixed Inductors Procurement Notes

Verify RoHS compliance status directly with the manufacturer or authorized distributors, as documentation indicates potential exemptions. Confirm the specific shipping configuration and lead times prior to ordering, as availability may vary. Ensure the selected variant matches the required current and inductance specifications for the target application circuit.

Fixed Inductors Selection Notes

Select this component when a shielded inductor with a 1 µH nominal value and 800 mA current handling capability is required. The 190 mΩ DC resistance makes it suitable for efficiency-sensitive designs. Consider the 0806 package dimensions for board space constraints and verify thermal performance within the -40°C to 125°C operating range.

Fixed Inductors Part Context

This part belongs to Samsung Electro-Mechanics' CIG series of power inductors. These components utilize metal composite materials to achieve superior saturation characteristics compared to traditional ferrite cores. The series is engineered for modern electronics requiring reliable power delivery in small form factors.

Fixed Inductors Replacement Considerations

Cross-reference with other 1 µH shielded SMD inductors rated for at least 800 mA and similar DCR values. Verify that substitute components match the 0806 package dimensions and operate within the same temperature range to ensure mechanical and electrical compatibility.
