CIM31U601NE

Chip Ferrite Bead Overview

The Samsung Electro-Mechanics CIM31U601NE is a ferrite bead chip designed for electromagnetic interference (EMI) suppression in electronic circuits. It features a single-line configuration housed in a 1206 (3216 Metric) surface-mount package with dimensions of 3.20mm length and 1.60mm width. The component exhibits an impedance of 600 Ohms at 100 MHz, providing effective noise filtering for high-frequency signals. It supports a maximum rated current of 500mA and maintains a maximum DC resistance (DCR) of 300 milliohms to minimize power loss. The device operates reliably within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Provides EMI suppression through high-impedance characteristics at target frequencies
• Supports surface-mount assembly for automated PCB manufacturing
• Maintains low DC resistance to preserve signal integrity under load

Chip Ferrite Bead Applications

• High-speed data line filtering
• Power supply output noise reduction
• Clock signal conditioning

Chip Ferrite Bead Procurement Notes

This component is officially obsolete and no longer manufactured by Samsung Electro-Mechanics. Procurement should focus on verified direct substitutes or parameter-equivalent alternatives from active production lines. Verify that replacement parts match the original impedance, current rating, and package dimensions to ensure circuit compatibility.

Chip Ferrite Bead Selection Notes

Selection requires matching the 600 Ohm impedance at 100 MHz and 500mA current handling capability. The 1206 package size must fit the existing footprint. Ensure the substitute part meets the -55°C to +125°C operating temperature range and RoHS3 compliance requirements for environmental safety.
