CIB21P300NE

Chip Ferrite Bead Overview

The CIB21P300NE is a single-line ferrite bead component manufactured by Samsung Electro-Mechanics, designed for high-frequency noise suppression in power lines. It features an impedance of 30 Ohms at 100 MHz and supports a maximum current rating of 6 Amperes. The device utilizes a surface-mount 0805 (2012 metric) package with dimensions of 2.00mm x 1.25mm and a maximum height of 1.10mm. It exhibits a maximum DC resistance of 10 milliohms and operates within a temperature range of -55°C to 125°C.

Chip Ferrite Bead Feature Summary

• Provides effective high-frequency noise attenuation for power supply lines through magnetic dissipation.
• Supports high-current applications up to 6A with low DC resistance to minimize voltage drop.
• Designed for compact surface-mount integration using standard 0805 footprint dimensions.

Chip Ferrite Bead Applications

• Power line filtering in portable electronic devices
• Noise suppression in automotive electronic control units
• Signal integrity management in communication modules

Chip Ferrite Bead Procurement Notes

Verify part status carefully as this component is officially listed as obsolete and no longer manufactured. Confirm availability of alternative sources or substitute components before finalizing design specifications. Ensure that any replacement parts meet the original electrical requirements including impedance, current rating, and physical dimensions to maintain circuit performance and reliability standards.

Chip Ferrite Bead Selection Notes

Select this component for applications requiring high-current handling capability alongside high-frequency noise suppression. The 0805 package size offers a balance between current capacity and board space efficiency. Consider the 30 Ohm impedance at 100 MHz when designing filters for specific noise frequencies. Ensure the operating environment stays within the specified -55°C to 125°C temperature range for optimal performance.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the CIS series from Samsung Electro-Mechanics, which focuses on passive components for signal and power line conditioning. The company specializes in MLCCs, inductors, and ferrite beads for mobile and automotive electronics. This specific model represents their legacy offering in high-current chip beads, now superseded by newer generations or alternative manufacturers due to end-of-life status.

Chip Ferrite Bead Replacement Considerations

The MPZ2012S300AT000 by TDK is a documented parameter-equivalent substitute. Verify that the replacement matches the 30 Ohm impedance at 100 MHz, 6A current rating, and 0805 package dimensions to ensure compatibility with existing footprints and circuit designs.
