CIM21J202NE

Chip Ferrite Bead Overview

The CIM21J202NE is a multi-layer ferrite bead manufactured by Samsung Electro-Mechanics in an 0805 (2012 metric) surface-mount package. It exhibits an impedance of 2000 ohms at 70 MHz with a tolerance of 25%. The component supports a maximum current rating of 0.5 A and features a maximum DC resistance of 0.5 ohms. Physical dimensions are 2.00 mm in length and 1.25 mm in width, with a maximum height of 1.10 mm.

Chip Ferrite Bead Feature Summary

• Multi-layer chip construction for compact high-frequency noise suppression
• High impedance characteristics effective at 70 MHz
• Surface-mount design suitable for automated assembly

Chip Ferrite Bead Applications

• Attenuating high-frequency noise on low-current supply branches
• Signal integrity protection in 3.3V systems
• EMI suppression in 5V power distribution networks

Chip Ferrite Bead Procurement Notes

Verify the manufacturer designation carefully, as sources may list Samsung Electro-Mechanics or Samsung Semiconductor. Confirm the specific impedance frequency point and tolerance requirements against your schematic. Ensure the 0805 footprint matches your PCB layout constraints before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when designing circuits requiring significant attenuation at 70 MHz with limited current capacity. The 0.5A rating restricts usage to low-power signal lines or auxiliary supplies rather than main power rails. Evaluate the 0.5-ohm DCR impact on voltage drop if used in sensitive analog paths.

Chip Ferrite Bead Part Context

This part belongs to the CIB/CIM series of chip beads from Samsung Electro-Mechanics. These components utilize multi-layer technology to provide efficient electromagnetic interference filtering in small form factors. The series is designed for general-purpose noise suppression in portable electronics and communication devices.
