FB201209T-400Y-S

Chip Ferrite Bead Overview

The FB201209T-400Y-S is a multilayer ferrite chip bead manufactured by Cal-Chip Electronics, Inc. It features an 0805 (2012 Metric) surface-mount package with dimensions of 2.0 mm length, 1.2 mm width, and 0.9 mm height. The component provides an impedance of 40 Ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 800 mA and has a maximum DC resistance of 0.05 Ohms. Designed for EMI/RFI attenuation, it utilizes multilayered magnetic material technology.

Chip Ferrite Bead Feature Summary

• Provides effective EMI and RFI attenuation through multilayered ferrite construction
• Eliminates the need for additional wiring when mounted directly onto the PCB
• Engineered for high solder heat resistance and outstanding solderability
• Optimized for volume production with high impedance characteristics

Chip Ferrite Bead Applications

• Various electronic equipment requiring signal line filtering
• Circuits where a stable ground is difficult to achieve
• Surface mounting applications using flow, reflow, or wave soldering processes

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value of 40 Ohms at 100 MHz against your circuit requirements. Confirm the 800 mA current rating is sufficient for the target application. Ensure the 0805 footprint matches the PCB layout. Check for RoHS compliance status if required by your manufacturing standards. Validate that the 0.05 Ohm DC resistance meets power loss constraints.

Chip Ferrite Bead Selection Notes

Select this component when a compact 0805 form factor is required for high-frequency noise suppression. The 40 Ohm impedance at 100 MHz makes it suitable for general-purpose signal lines. Consider the 800 mA current handling capability for power integrity. The low DC resistance minimizes voltage drop in the signal path. Multilayer technology offers robust mechanical strength for automated assembly.
