FBU321611T-500Y-S

Chip Ferrite Bead Overview

The FBU321611T-500Y-S is a power line ferrite bead from the FBU series by Cal-Chip Electronics, Inc. It features a 1206 (3216 Metric) surface mount package with dimensions of 0.126 inches in length and 0.063 inches in width. The component provides an impedance of 50 Ohms at 100 MHz and supports a maximum rated current of 6A. Its DC resistance is 10 milliohms, and it operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Designed for power line filtering applications
• Low DC resistance for minimal signal loss
• High current handling capability up to 6A
• Wide operating temperature range

Chip Ferrite Bead Applications

• Power supply noise suppression
• DC-DC converter output filtering
• General purpose EMI suppression in electronic circuits

Chip Ferrite Bead Procurement Notes

Verify the manufacturer part number FBU321611T-500Y-S against official Cal-Chip Electronics documentation to ensure authenticity. Confirm that the specific impedance value of 50 Ohms at 100 MHz matches your circuit requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the 1206 package size fits your PCB layout constraints.

Chip Ferrite Bead Selection Notes

Select this component when a low DC resistance of 10 milliohms is critical for maintaining efficiency in high-current paths. The 6A rating makes it suitable for power rails where standard beads might saturate. Consider the 1206 footprint availability in your design. The 50 Ohm impedance at 100 MHz should be validated against the specific noise frequencies present in your application.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the FBU series, which is characterized by its robust construction for power line applications. The 1206 package offers a balance between current handling and board space efficiency. It is distinct from lower-current signal line beads due to its 6A rating and ultra-low DCR specification.

Chip Ferrite Bead Replacement Considerations

The FBU321611T-121Y-S is listed as a parameter equivalent alternative from the same manufacturer. Verify that the impedance differences do not impact your filter design before substitution.
