FB201209T-201Y-S

Chip Ferrite Bead Overview

The FB201209T-201Y-S is a multilayer ferrite chip bead manufactured by Cal-Chip Electronics, Inc. It operates as a single-function EMI suppressor in an 0805 (2012 Metric) surface-mount package. The component exhibits an impedance of 200 Ohms at 100 MHz and a maximum DC resistance of 250 milliohms. Designed for high-frequency signal filtering, it provides effective attenuation for electronic equipment while maintaining compatibility with standard reflow and wave soldering processes.

Chip Ferrite Bead Feature Summary

• Provides powerful EMI/RFI attenuation through multilayer ferrite technology without requiring additional wiring
• Engineered for direct surface mounting on PCBs to eliminate noise interference
• Features robust electrode strength and high resistance to solder heat during assembly

Chip Ferrite Bead Applications

• High-frequency signal filtering in electronic circuits
• EMI suppression for portable devices using surface mount technology
• Noise reduction in power lines for compact electronic equipment

Chip Ferrite Bead Procurement Notes

Verify the specific impedance tolerance and current rating requirements against your circuit design before ordering. Confirm RoHS compliance status if restricted substances are prohibited in your manufacturing process. Ensure the 0805 footprint matches your PCB layout constraints. Check for any lead-free certification documentation required by your regional regulations.

Chip Ferrite Bead Selection Notes

Select this component when a 200 Ohm impedance at 100 MHz is required for noise suppression. The low DC resistance minimizes voltage drop in power lines. Consider the 0805 package size for space-constrained designs. Evaluate the current handling capabilities relative to your application's peak load to ensure reliable operation under thermal stress.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the FB series from Cal-Chip Electronics, designed for surface-mount applications. The series utilizes multilayer technology to achieve high impedance in small footprints. These components are intended to replace conventional wire-wound beads, offering easier integration into automated assembly lines while providing comparable or superior noise suppression performance.
