FB201209T-310Y-S

Chip Ferrite Bead Overview

The FB201209T-310Y-S is a single-function ferrite chip EMI suppressor manufactured by Cal-Chip Electronics, Inc. Designed for surface mount applications in the 0805 (2012 Metric) package, this component utilizes multilayered ferrite technology to provide effective electromagnetic interference attenuation. It features a nominal impedance of 31 Ohms at 100 MHz and supports a maximum current rating of 0.3 Amperes. The device exhibits a low DC resistance of 100 milliohms, ensuring minimal signal loss while maintaining high impedance characteristics for noise suppression.

Chip Ferrite Bead Feature Summary

• Multilayered ferrite construction provides strong electrode strength and solder heat resistance
• Designed for direct PCB mounting to eliminate EMI/RFI without requiring additional wiring
• Optimized for flow, reflow, and wave soldering processes required for surface mounting

Chip Ferrite Bead Applications

• EMI/RFI attenuation in electronic equipment
• Surface mount circuit board filtering
• Signal line noise suppression

Chip Ferrite Bead Procurement Notes

Verify the specific manufacturer designation as Cal-Chip Electronics, Inc., noting that some listings may reference alternative branding or distributors. Confirm the package size is 0805 and the impedance value is 31 Ohms at 100 MHz. Ensure the component meets RoHS compliance standards if required for your assembly process. Cross-reference the part number suffix to confirm it matches the exact electrical specifications needed for your design.

Chip Ferrite Bead Selection Notes

Select this component when a compact 0805 footprint is required for single-line noise suppression. The 31 Ohm impedance at 100 MHz makes it suitable for general-purpose EMI filtering where moderate attenuation is sufficient. Consider the 0.3A current rating to ensure the component can handle the operating current without saturation. The low DC resistance helps maintain signal integrity in power or data lines.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the FB series of multilayer chip beads from Cal-Chip Electronics. These components are engineered to replace conventional wire-wound beads, offering easier integration into automated surface mount production lines. The series is characterized by its ability to provide high impedance in a small volume, making it ideal for space-constrained modern electronics designs.
