CIM21J221NE

Chip Ferrite Bead Overview

The CIM21J221NE is a single-line ferrite bead from the Samsung Electro-Mechanics CIM21 series, housed in an 0805 (2012 Metric) surface-mount package. It provides an impedance of 220 Ohms at 100 MHz with a maximum DC resistance of 50 milliohms and a rated current of 1.5 Amperes. The component operates within a temperature range of -55°C to 125°C and measures 2.00mm x 1.25mm x 1.10mm.

Chip Ferrite Bead Feature Summary

• Provides high-impedance noise suppression for power lines in the 100 MHz frequency range
• Features low DC resistance to minimize voltage drop and power loss in high-current applications
• Utilizes a compact 0805 footprint suitable for space-constrained printed circuit board designs

Chip Ferrite Bead Applications

• Noise filtering on power supply lines
• Electromagnetic interference suppression in portable electronics
• Signal integrity management in high-density circuit boards

Chip Ferrite Bead Procurement Notes

Verify component status as this part may be discontinued or subject to end-of-life notices. Confirm availability through authorized distributors and check for parameter-equivalent alternatives if original stock is unavailable. Ensure compliance with RoHS3 specifications and lead time requirements before finalizing procurement plans.

Chip Ferrite Bead Selection Notes

Select this component when a 220 Ohm impedance at 100 MHz is required for a single-line power filter. Ensure the application current does not exceed the 1.5A rating and that the 0805 package dimensions fit the design constraints. Consider thermal performance within the specified operating temperature range during selection.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the CIM21 series of chip beads designed for broad impedance characteristics. The series targets noise suppression in specific frequency bands using multilayer ceramic technology. The CIM21 variant offers a balance between size and performance for general-purpose electronic circuits requiring EMI mitigation.

Chip Ferrite Bead Replacement Considerations
