CIM21J102NE

Chip Ferrite Bead Overview

The CIM21J102NE is a ferrite bead from the Samsung Electro-Mechanics CIM21 series, designed for EMI suppression in high-frequency circuits. It features a single-line configuration housed in an 0805 (2012 Metric) surface-mount package with dimensions of 2.0mm length and 1.25mm width. The component exhibits an impedance of 1 kOhms at 100 MHz and supports a rated current of 500mA. It operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Closed magnetic circuit configuration prevents crosstalk and supports high-density PCB layouts.
• Monolithic inorganic material construction ensures high reliability and stability.
• Optimized geometry facilitates automatic mounting without directionality constraints.

Chip Ferrite Bead Applications

• High frequency EMI prevention in computers
• Noise suppression in printers and VCRs
• Signal filtering in mobile phones and TVs

Chip Ferrite Bead Procurement Notes

This component is officially obsolete and no longer manufactured by Samsung Electro-Mechanics. Procurement should focus on verified parameter-equivalent substitutes available from other manufacturers. Verify that replacement parts match the original impedance, current rating, and package dimensions to ensure circuit compatibility and performance integrity.

Chip Ferrite Bead Selection Notes

Select this part for applications requiring specific 1 kOhm impedance at 100 MHz within an 0805 footprint. Due to its discontinued status, engineers must evaluate alternative components that maintain identical electrical characteristics and thermal ratings. Ensure the substitute supports the required 500mA current handling and fits the existing land pattern design constraints.

Chip Ferrite Bead Part Context

The CIM21J102NE belongs to the CIM21 series of multi-layer chip beads intended for EMI suppression. This series utilizes monolithic inorganic materials to provide reliable noise filtering in compact electronic devices. The component is characterized by its closed magnetic circuit design, which minimizes interference between adjacent components on the printed circuit board.

Chip Ferrite Bead Replacement Considerations

Public confirmed substitute: BLM21PG221SN1D (Murata Electronics). This part offers parameter equivalence for the discontinued CIM21J102NE. Verify that the substitute matches the 0805 package size and functional requirements before integration into the design.
