FBMH4532HM681-T

Chip Ferrite Bead Overview

The FBMH4532HM681-T is a single-line ferrite bead chip manufactured by Taiyo Yuden, designed for power line applications. It features an impedance of 680 Ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 4A and has a maximum DC resistance (DCR) of 28 milliohms. It utilizes a surface-mount 1812 package with dimensions of 4.50mm x 3.20mm and a maximum height of 3.50mm. The device operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high-current suppression capabilities suitable for automotive-grade power lines
• Offers low DC resistance to minimize voltage drop in power distribution circuits
• Features a shielded design to effectively attenuate electromagnetic interference

Chip Ferrite Bead Applications

• Automotive power line filtering
• Industrial equipment EMI suppression
• Medical equipment noise reduction

Chip Ferrite Bead Procurement Notes

Verify the specific suffix and packaging configuration against official distributor catalogs to ensure compatibility with automated assembly processes. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Cross-reference manufacturer part numbers with authorized supplier databases to prevent counterfeit components. Ensure storage conditions align with specified humidity sensitivity classifications.

Chip Ferrite Bead Selection Notes

Select this component when designing circuits requiring significant current handling alongside high-frequency noise attenuation. The 4A rating makes it suitable for main power rails where lower-impedance beads would saturate. Evaluate thermal management needs given the low DCR value. Consider the physical footprint constraints of the 1812 package relative to available PCB real estate.
