FB201209T-520Y-S

Chip Ferrite Bead Overview

The FB201209T-520Y-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 with dimensions of 2.0 mm length, 1.2 mm width, and 0.9 mm height. The component provides an impedance of 52 Ohms at 100 MHz for one signal line. It supports a maximum current rating of 300 mA and features a low DC resistance of 150 mOhm.

Chip Ferrite Bead Feature Summary

• Multilayer ferrite technology designed for effective EMI/RFI attenuation without requiring additional wiring
• Optimized for surface mounting applications including flow, reflow, and wave soldering processes
• High electrode strength and solder heat resistance ensuring reliability during assembly

Chip Ferrite Bead Applications

• EMI suppression on high-speed digital signal lines
• Noise filtering in compact consumer electronic devices
• Power line filtering in space-constrained circuit boards

Chip Ferrite Bead Procurement Notes

Verify the specific impedance tolerance and current rating requirements against your circuit design before ordering. Confirm that the 0805 footprint matches your PCB layout constraints. Ensure compatibility with your chosen soldering profile, particularly regarding thermal resistance during reflow or wave soldering processes to maintain component integrity.

Chip Ferrite Bead Selection Notes

Select this component when space is limited and a surface-mount solution is required for noise suppression. The 52 Ohm impedance at 100 MHz targets common high-frequency interference. Ensure the 300 mA current capacity exceeds the maximum operating current of the protected line to prevent saturation or excessive heating during normal operation.

Chip Ferrite Bead Part Context

This part belongs to the Cal-Chip Electronics multilayer ferrite chip bead series. These components utilize magnetic material and multilayered technology to provide superior performance compared to conventional beads. The series is engineered to offer high impedance values while maintaining small physical profiles suitable for modern dense PCB designs.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include FB201209T-601Y-S and FB201209T-102Y-S from Cal-Chip Electronics. Cross-manufacturer equivalents such as Pulse Electronics BBGK00201209601Y00 may be considered if electrical parameters match exactly.
