FB321611T-121Y-S-1

Chip Ferrite Bead Overview

The FB321611T-121Y-S-1 is a multilayer ferrite chip bead manufactured by Cal-Chip Electronics, Inc. It features a 1206 (3216 Metric) surface mount package with dimensions of 3.2 mm length, 1.6 mm width, and 1.30 mm maximum height. The component provides an impedance of 120 Ohms at 100 MHz with a tolerance of ±25%. It has a maximum DC resistance of 0.15 Ohms and supports a current rating of 600 mA. The operating temperature range extends from -55°C to 125°C.

Chip Ferrite Bead Feature Summary

• Multilayer ferrite construction for effective EMI/RFI attenuation
• Designed for surface mounting via flow, reflow, or wave soldering
• High electrode strength and solder heat resistance

Chip Ferrite Bead Applications

• Various electronic equipment
• Circuits requiring stable ground
• Power line filtering in high-frequency applications

Chip Ferrite Bead Procurement Notes

Verify the specific suffix '-1' against official Cal-Chip documentation to confirm the 600 mA current rating and 0.15 Ohm DCR specifications. Ensure the 1206 package footprint matches the target PCB design. Confirm RoHS compliance status directly with the manufacturer or authorized distributor before procurement.

Chip Ferrite Bead Selection Notes

Select this component when a 1206 footprint is required for high-current EMI suppression. The 600 mA rating distinguishes it from lower-current variants like the FB321611T-121Y-S series. Verify that the 120 Ohm impedance at 100 MHz aligns with the noise frequency spectrum of the application circuit.

Chip Ferrite Bead Part Context

This part belongs to the FB Series of multilayer ferrite chip beads from Cal-Chip Electronics. These components utilize magnetic material and multilayered technology to provide EMI suppression without requiring additional wiring. The series is designed for wide-range applications due to available size variations.

Chip Ferrite Bead Replacement Considerations

The FB321611T-121Y-S-2 is a public confirmed substitute within the same series. Verify electrical parameters such as current rating and DC resistance match the original requirements before substitution.
