FB100505T-121Y-S

Chip Ferrite Bead Overview

The FB100505T-121Y-S is a surface-mount ferrite chip bead manufactured by Cal-Chip Electronics, Inc. It operates at a frequency of 100 MHz with an output impedance of 120 Ohms. The component supports a maximum current of 300 mA and features a low DC resistance of 200 mOhms. Housed in a compact 0402 (1005 Metric) package measuring 1.0 mm in length, 0.5 mm in width, and 0.5 mm in height, it provides EMI/RFI attenuation for electronic circuits.

Chip Ferrite Bead Feature Summary

• Provides effective EMI and RFI attenuation through multilayer ferrite technology
• Designed for direct surface mounting without requiring additional wiring
• Offers high solder heat resistance suitable for reflow and wave soldering processes

Chip Ferrite Bead Applications

• Power supply filtering
• Battery charger circuits
• Portable electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against the manufacturer's official documentation to confirm exact electrical tolerances and packaging specifications. Ensure compliance with RoHS standards and lead-free requirements as stated in the datasheet. Confirm that the 0402 footprint matches the target PCB design constraints before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when space-constrained designs require EMI suppression in the 0402 package size. The 120 Ohm impedance at 100 MHz makes it suitable for general-purpose noise filtering. Ensure the operating current does not exceed the 300 mA rating to maintain performance and prevent saturation.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the FB series of multilayer chip beads from Cal-Chip Electronics. These components utilize magnetic material and multilayered technology to provide electrode strength and solderability. They are engineered specifically for automatic mounting equipment and high-density circuit applications.

Chip Ferrite Bead Replacement Considerations

Consult official substitution lists for equivalent ferrite beads with matching 120 Ohm impedance and 0402 dimensions. Verify that alternative parts meet the same current handling and thermal resistance requirements.
