CIC21P300NE

Chip Ferrite Bead Overview

The CIC21P300NE is a single-line power line ferrite bead from the CIS series, manufactured by Samsung Electro-Mechanics. It features a 0805 (2012 Metric) surface-mount package with dimensions of 2.00mm x 1.25mm and a maximum height of 1.10mm. The component provides an impedance of 30 Ohms at 100 MHz and supports a maximum rated current of 6A. Its DC resistance (DCR) is 10 milliohms. It operates within a temperature range of -55°C to 125°C and is RoHS3 compliant.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression for power lines through high-frequency impedance characteristics.
• Designed for surface-mount assembly in compact electronic circuits.
• Capable of handling high continuous current loads suitable for power supply applications.

Chip Ferrite Bead Applications

Chip Ferrite Bead Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Samsung Electro-Mechanics. Product Change Notification Mult Devs - End of Life was issued on June 1, 2020. Procurement should focus on verified substitute parts rather than original stock. Verify compatibility with existing designs using official datasheets before implementation.

Chip Ferrite Bead Selection Notes

Select this part only if legacy design compatibility is required. For new designs, consider active alternatives with similar electrical specifications. Ensure the 0805 footprint and 6A current rating meet system requirements. Check thermal performance within the -55°C to 125°C operating range during integration.

Chip Ferrite Bead Part Context
