CIM05U301NC

Chip Ferrite Bead Overview

The CIM05U301NC is a surface-mount ferrite bead manufactured by Samsung Electro-Mechanics. It features a 0402 (1005 metric) package size and provides an impedance of 300 Ohms at 100 MHz. The component has a rated current capacity of 400 mA and a maximum DC resistance of 450 milliohms. Designed for single-line noise suppression, it utilizes a feed-through structure to effectively attenuate high-frequency electromagnetic interference in compact electronic circuits.

Chip Ferrite Bead Feature Summary

• Provides effective high-frequency noise attenuation through a dedicated feed-through structure
• Compact 0402 surface-mount footprint suitable for space-constrained PCB layouts
• Low DC resistance minimizes power loss during normal signal transmission

Chip Ferrite Bead Applications

• High-speed data line noise suppression
• Power supply input filtering
• RF circuit interference mitigation

Chip Ferrite Bead Procurement Notes

Verify the specific impedance tolerance and current rating requirements against the official datasheet before finalizing procurement. Confirm that the 0402 package dimensions align with the target PCB land pattern. Ensure the selected supplier provides authentic components from Samsung Electro-Mechanics to guarantee performance consistency and reliability in critical applications.

Chip Ferrite Bead Selection Notes

Select this component when high impedance at 100 MHz is required within a minimal 0402 footprint. Evaluate the 400 mA current limit to ensure it exceeds the maximum operating current of the protected circuit. Consider the low DC resistance value to prevent excessive voltage drop across the component during steady-state operation.

Chip Ferrite Bead Part Context

This ferrite bead belongs to Samsung Electro-Mechanics' passive component portfolio, specifically designed for EMI suppression. It complements their broader range of capacitors and inductors by addressing high-frequency noise issues in modern electronics. The part supports the industry trend toward miniaturization while maintaining robust signal integrity protection.

Chip Ferrite Bead Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any alternative maintains identical 300 Ohm impedance at 100 MHz and compatible current handling capabilities.
