CIC05P121NC

Chip Ferrite Bead Overview

The CIC05P121NC is a single-line ferrite bead from the Samsung Electro-Mechanics CIC05 series, designed for power line filtering. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm length and 0.50mm width. The component provides an impedance of 120 Ohms at 100 MHz. It supports a maximum rated current of 1.1A and has a maximum DC resistance of 50 milliohms. Operating temperature ranges from -55°C to 125°C.

Chip Ferrite Bead Feature Summary

• Provides high impedance attenuation for noise suppression on power lines
• Compact 0402 surface-mount footprint for space-constrained designs
• Rated for continuous current up to 1.1A with low DC resistance

Chip Ferrite Bead Applications

• Power supply input filtering
• Battery charger circuits
• Portable electronic devices
• Energy-efficient system power rails

Chip Ferrite Bead Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS3 compliance and REACH status prior to integration. Check for recent product change notices or end-of-life announcements from Samsung Electro-Mechanics to ensure long-term availability for production runs.

Chip Ferrite Bead Selection Notes

Select this component when 120 Ohm impedance at 100 MHz is required for power line noise reduction. Ensure the 1.1A current rating meets the application's peak load requirements. The 0402 package size must fit the PCB layout constraints. Consider thermal performance within the -55°C to 125°C operating range.
