CIM31J601NE

Chip Ferrite Bead Overview

The Samsung Electro-Mechanics CIM31J601NE is a multi-layer ferrite bead component designed for electromagnetic interference (EMI) suppression in electronic circuits. It features an impedance of 600 Ohms at 100 MHz and supports a maximum current rating of 400 mA to 600 mA, depending on the specific datasheet reference. The device exhibits a maximum DC resistance (DCR) of 300 mOhm. It is housed in a standard 1206 (3216 Metric) surface-mount package with physical dimensions of 3.20 mm x 1.60 mm. This component is classified as obsolete and is no longer manufactured by the producer.

Chip Ferrite Bead Feature Summary

• Multi-layer construction for effective high-frequency noise attenuation
• Low DC resistance to minimize power loss in signal paths
• Surface-mount design compatible with automated assembly processes

Chip Ferrite Bead Applications

• High-speed data line filtering
• Power supply output decoupling
• Clock signal noise suppression

Chip Ferrite Bead Procurement Notes

This component is officially marked as obsolete and no longer manufactured by Samsung Electro-Mechanics. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the condition of inventory, as availability is limited and subject to existing warehouse stocks rather than active production runs.

Chip Ferrite Bead Selection Notes

Engineers replacing this part should evaluate ferrite beads with identical 1206 footprints and comparable impedance characteristics at 100 MHz. Current handling capabilities must meet or exceed the original 400-600 mA requirement to ensure circuit reliability. Verification of DCR limits and thermal performance under load is essential when selecting alternative components from different manufacturers.

Chip Ferrite Bead Part Context

The CIM31 series represents Samsung Electro-Mechanics' line of chip ferrite beads intended for EMI suppression. The CIM31J601NE specifically denotes a 600 Ohm impedance variant within this family. As an obsolete part, it belongs to a generation of components that have been superseded by newer product lines offering improved performance or updated manufacturing standards.
