FB321611T-500Y-S

Chip Ferrite Bead Overview

The FB321611T-500Y-S is a single-function ferrite chip bead manufactured by Cal-Chip Electronics, Inc. Housed in a surface-mount 1206 (3216 Metric) package with dimensions of 3.2 mm length, 1.6 mm width, and a maximum height of 1.30 mm, this component is designed for EMI/RFI suppression. It exhibits an impedance of 50 Ohms at 100 MHz and supports a maximum current rating of 800 mA. The device features a maximum DC resistance of 150 mOhm and is constructed using multilayer ferrite technology.

Chip Ferrite Bead Feature Summary

• Provides effective EMI and RFI attenuation through high impedance characteristics without requiring additional wiring
• Utilizes multilayered ferrite material to ensure strong electrode integrity and solder heat resistance
• Engineered for reliable performance in flow, reflow, and wave soldering processes required for surface mounting

Chip Ferrite Bead Applications

• Signal line filtering in electronic equipment
• EMI suppression on printed circuit boards
• RFI attenuation in surface mount applications

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before integration. Confirm that the 1206 package dimensions align with the target PCB footprint. Ensure compliance with RoHS standards if required by the end product specifications. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Chip Ferrite Bead Selection Notes

Select this component when a low DC resistance and moderate impedance are required for signal lines carrying up to 800 mA. The 1206 package offers a balance between size and power handling capability. Consider the 50 Ohm impedance at 100 MHz for noise frequencies in that range. Evaluate thermal management requirements given the surface mount construction and soldering compatibility.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the FB series of multilayer ceramic components from Cal-Chip Electronics. These parts are designed to replace conventional wire-wound beads, offering easier surface mounting. The series utilizes advanced multilayer technology to provide high reliability and volumetric efficiency for modern electronic assemblies.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other 1206 ferrite beads with 50 Ohm impedance at 100 MHz and similar current ratings. Verify package dimensions and terminal configurations match the existing design. Check impedance curves to ensure equivalent noise suppression performance across the target frequency spectrum.
