CIC21P331NE

Chip Ferrite Bead Overview

The CIC21P331NE is a single-line power line ferrite bead manufactured by Samsung Electro-Mechanics. It features an impedance of 330 Ohms at 100 MHz and supports a maximum current rating of 2A. The component utilizes a 0805 (2012 Metric) surface-mount package with a low DC resistance of 50mOhm. Designed for noise suppression in electronic circuits, it effectively filters high-frequency interference while maintaining signal integrity under specified load conditions.

Chip Ferrite Bead Feature Summary

• Provides effective noise suppression for power lines through high impedance characteristics at target frequencies
• Supports continuous current loads up to 2A with minimal voltage drop due to low DC resistance
• Utilizes a compact 0805 surface-mount footprint to optimize board space efficiency

Chip Ferrite Bead Applications

• Noise filtering in portable electronic devices
• Signal integrity protection in consumer electronics power supplies
• High-frequency interference suppression in automotive infotainment systems

Chip Ferrite Bead Procurement Notes

Verify the specific datasheet version for the CIC21P331NE to confirm impedance tolerance and thermal derating curves. Ensure compatibility with standard reflow soldering profiles for 0805 packages. Cross-reference manufacturer documentation for any recent design changes or end-of-life notices before finalizing procurement plans.

Chip Ferrite Bead Selection Notes

Select this component when circuit requirements demand 330 Ohm attenuation at 100 MHz with 2A current capacity. Evaluate PCB layout constraints to ensure adequate spacing for the 0805 package. Compare against alternative ferrite beads if lower DC resistance or different impedance profiles are required for specific power rail applications.

Chip Ferrite Bead Part Context

Samsung Electro-Mechanics produces passive components including MLCCs, inductors, and ferrite beads. The CIC series represents their ferrite bead lineup designed for EMI suppression. This specific model targets applications requiring reliable noise reduction in compact electronic assemblies without compromising current handling capabilities.

Chip Ferrite Bead Replacement Considerations

Consult official Samsung Electro-Mechanics substitution guides for verified alternatives. Ensure replacement parts match the 330 Ohm @ 100 MHz impedance and 2A current rating. Verify package compatibility and thermal performance before integrating substitute components into existing designs.
