CIC21P221NE

Chip Ferrite Bead Overview

The CIC21P221NE is a single-line power line ferrite bead 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 0.70mm. The component provides an impedance of 220 Ohms at 100 MHz and supports a rated current of 3.2A. Its maximum DC resistance is 35 milliohms. It operates within a temperature range of -55°C to 125°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Designed for power line filtering to suppress electromagnetic interference in electronic circuits
• Utilizes a compact 0805 surface-mount footprint for efficient board space utilization
• Capable of handling high continuous current ratings suitable for power supply applications

Chip Ferrite Bead Applications

• Power supply input/output filtering
• Electromagnetic interference suppression in digital circuits
• Noise reduction in automotive electronic control units

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'P' against datasheets to confirm the 3.2A rating and 35mOhm DCR, as other series variants like 'J' differ significantly. Confirm RoHS3 compliance status for your region. Check for end-of-life notices or alternative part numbers if long-term availability is required. Ensure the 0805 package size fits your PCB layout constraints.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance path is needed for power lines while attenuating high-frequency noise above 100 MHz. The 3.2A current rating makes it suitable for main power rails where lower-current beads would saturate. Compare the 35mOhm DC resistance against voltage drop requirements in the circuit design. Ensure the operating temperature range meets the environmental conditions of the final assembly.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the CIC21 series from Samsung Electro-Mechanics, which focuses on chip beads for general electronic applications. The series offers various impedance and current combinations in standard metric packages. This specific model targets power integrity solutions requiring moderate impedance and high current capacity in a small form factor.
