FB321611T-121Y-S-2

Chip Ferrite Bead Overview

The FB321611T-121Y-S-2 is a single-function surface-mount ferrite chip bead manufactured by Cal-Chip Electronics. Housed in a 1206 (3216 Metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 1.1 mm height, it operates within a temperature range of -55°C to 125°C. The component provides an impedance of 120 Ohms at 100 MHz and supports a maximum current rating of 900 mA. Its low DC resistance of 150 mOhm ensures minimal signal loss while effectively attenuating electromagnetic interference.

Chip Ferrite Bead Feature Summary

• Provides high impedance for effective EMI/RFI attenuation without requiring additional wiring
• Multilayer construction offers strong electrode integrity and solder heat resistance
• Optimized for reliable performance in flow, reflow, and wave soldering processes

Chip Ferrite Bead Applications

• High-power motor control cabinets
• Microcontroller circuit protection
• General-purpose EMI suppression in surface mount assemblies

Chip Ferrite Bead Procurement Notes

Verify the specific suffix '-2' against official Cal-Chip documentation to confirm packaging details and exact electrical tolerances. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a 1206 footprint is required for high-current applications up to 900 mA. The 120 Ohm impedance at 100 MHz makes it suitable for broadband noise suppression where low DC resistance is critical for maintaining signal integrity in power lines.

Chip Ferrite Bead Part Context

This part belongs to the FB series of multilayer ferrite chip beads from Cal-Chip Electronics. These components utilize specialized magnetic materials to deliver superior attenuation compared to conventional beads, designed specifically for modern surface mounting equipment and automated assembly lines.

Chip Ferrite Bead Replacement Considerations

Cross-reference with FB321611T-121Y-S-1 for similar specifications but verify current ratings and packaging differences. Ensure any substitute matches the 1206 package size and 120 Ohm impedance profile.
