CIC31J301NC

Chip Ferrite Bead Overview

The CIC31J301NC is a single-line power line ferrite bead manufactured by Samsung Electro-Mechanics. It features a 1206 (3216 Metric) surface mount package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.30mm. The component provides an impedance of 300 Ohms at 100 MHz and supports a maximum current rating of 3A. Its DC resistance (DCR) is limited to a maximum of 50 milliohms. The device operates within a temperature range of -55°C to +125°C and is RoHS compliant.

Chip Ferrite Bead Feature Summary

• Provides high impedance filtering for power lines at 100 MHz
• Designed for surface mount assembly in compact layouts
• Capable of handling continuous currents up to 3A

Chip Ferrite Bead Applications

• Power supply input filtering
• Noise suppression on data lines
• EMI reduction in portable electronics

Chip Ferrite Bead Procurement Notes

Verify the obsolete status of this specific part number before design finalization. Confirm that the 300 Ohm impedance and 3A current rating align with system requirements. Check for parameter-equivalent alternatives if production continuity is required. Ensure the 1206 footprint matches the PCB layout constraints.

Chip Ferrite Bead Selection Notes

Select this component when high attenuation at 100 MHz is necessary for power line noise control. The low DCR minimizes voltage drop under load. Consider the thermal performance within the specified operating range. Evaluate space constraints against the standard 1206 package size.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the CIC31 series from Samsung Electro-Mechanics, designed for passive EMI suppression. It complements other components like the CIC31J121NE, which offers lower impedance but similar packaging. These parts are essential for maintaining signal integrity in dense electronic assemblies.
