FB12YTYH121

Chip Ferrite Bead Overview

The FB12YTYH121 is a power line ferrite bead manufactured by Stackpole Electronics Inc. It features an impedance of 120 Ohms at 100 MHz and a DC resistance of 30 milliohms. The component supports a current rating of 4 Amperes and is housed in an 1812 (4532 Metric) surface-mount package.

Chip Ferrite Bead Feature Summary

• Designed for power line noise suppression applications
• Provides high current handling capability up to 4A
• Utilizes a robust 1812 surface-mount form factor

Chip Ferrite Bead Applications

• Power supply input filtering
• DC-DC converter output noise reduction
• General-purpose EMI suppression on power traces

Chip Ferrite Bead Procurement Notes

Verify the specific impedance tolerance and current derating curves against the official Stackpole datasheet before finalizing design integration. Confirm that the 1812 footprint dimensions align with the target PCB layout constraints. Ensure compliance with RoHS3 standards as indicated in manufacturer documentation.

Chip Ferrite Bead Selection Notes

Select this component when high-current power line filtering is required in a compact surface-mount format. The 120 Ohm impedance at 100 MHz targets common switching noise frequencies. Compare thermal performance and saturation characteristics against alternative ferrite beads if higher current capacity or different frequency responses are needed.

Chip Ferrite Bead Part Context

This ferrite bead belongs to Stackpole's FB series, which focuses on passive components for signal integrity and power management. The 1812 package size offers a balance between current handling capacity and board space efficiency, suitable for dense electronic assemblies requiring effective electromagnetic interference mitigation.
