CIM05J221NC

Chip Ferrite Bead Overview

The CIM05J221NC is a ferrite bead and chip component manufactured by Samsung Electro-Mechanics, belonging to the CIM05 series. It is designed for electromagnetic interference (EMI) suppression in compact electronic circuits. The device features a single-line configuration housed in a 0402 (1005 Metric) surface-mount package with dimensions of 1.00mm length and 0.50mm width. Key electrical specifications include an impedance of 220 Ohms at 100 MHz and a maximum DC resistance of 800 milliohms. The component supports a rated current of 250mA and operates within a temperature range of -55°C to 125°C. The maximum height is 0.55mm. This part is currently obsolete and no longer in production.

Chip Ferrite Bead Feature Summary

Chip Ferrite Bead Procurement Notes

This component is officially classified as obsolete and has been discontinued by the manufacturer. Procurement must rely on third-party distributors holding remaining stock or authorized surplus channels. Verify authenticity carefully due to end-of-life status. Confirm that substitute components meet identical impedance, current rating, and dimensional requirements before integration into new designs.

Chip Ferrite Bead Selection Notes

Select this component only for legacy board revisions or direct replacement scenarios where the original design constraints are preserved. For new designs, evaluate alternative ferrite beads with comparable 220 Ohm impedance at 100 MHz and 250mA current handling. Ensure the substitute maintains the 0402 package size and thermal stability range to fit existing footprints without mechanical modification.

Chip Ferrite Bead Part Context

The CIM05J221NC belongs to Samsung Electro-Mechanics' CIM05 series of chip beads. This series focuses on providing EMI suppression solutions in small form factors. The J221 suffix indicates the specific impedance value of 220 Ohms. The product falls under the broader category of passive filters used for noise control in high-frequency digital and analog circuits.

Chip Ferrite Bead Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include Pulse Electronics BBSY00100505102Y00 and Cal-Chip Electronics FB100505T-102Y-S-1. These alternatives offer matching impedance and current ratings. Verify pin compatibility and thermal performance before adoption.
