CIM10U121NC

Chip Ferrite Bead Overview

The Samsung Electro-Mechanics CIM10U121NC is a single-line ferrite bead chip inductance component designed for surface-mount technology. It features a 0603 (1608 Metric) package with dimensions of 1.60mm x 0.80mm and a maximum height of 0.95mm. The device provides an impedance of 120 Ohms at 100 MHz, with a rated current capacity of 400mA and a maximum DC resistance of 250 milliohms. It operates within a temperature range of -55°C to 125°C.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies
• Utilizes a compact 0603 surface-mount footprint for space-constrained circuit board layouts
• Supports single-line signal integrity protection with low DC resistance to minimize power loss

Chip Ferrite Bead Applications

• High-speed data line filtering in portable electronic devices
• Power supply noise attenuation in mobile communication modules
• EMI suppression on clock lines in consumer electronics

Chip Ferrite Bead Procurement Notes

Verify component status as the CIM10U121NC is officially listed as obsolete and no longer manufactured by Samsung Electro-Mechanics. Confirm availability of end-of-life inventory or authorized substitutes before integration into new designs. Check for non-cancelable and non-returnable terms if sourcing remaining stock from distributors. Ensure RoHS3 compliance documentation is available for regulatory adherence.

Chip Ferrite Bead Selection Notes

Select this component only for legacy system maintenance or repair where original specifications are mandatory. Evaluate alternative ferrite beads with identical 120 Ohm impedance at 100 MHz and compatible 0603 footprints for new designs. Consider thermal performance and current rating requirements relative to the 400mA limit. Validate that substitute components meet the same MSL and environmental operating standards.

Chip Ferrite Bead Part Context

This part belongs to the CIM10 series of multilayer ferrite beads produced by Samsung Electro-Mechanics. The series is engineered for EMI suppression in compact electronic assemblies. The CIM10U121NC specifically targets applications requiring moderate impedance values in small form factors. Production has ceased, shifting its role to replacement parts for existing hardware.

Chip Ferrite Bead Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly provided in the source material. Designers should seek equivalent ferrite beads from other manufacturers that match the 120 Ohm @ 100 MHz specification, 0603 package size, and 400mA current rating.
