FBMJ2125HS250NT

Chip Ferrite Bead Overview

The Taiyo Yuden FBMJ2125HS250NT is a single-line ferrite bead in the FB series, designed for surface mount applications. It features an 0805 (2012 metric) package with dimensions of 2.00mm length, 1.25mm width, and a maximum height of 1.05mm. The component provides an impedance of 25 Ohms at 100 MHz with a tolerance of 30%. It supports a maximum DC current of 6A and has a maximum DC resistance of 4 mOhms. Operating temperatures range from -40°C to +125°C. It is AEC-Q200 qualified and RoHS3 compliant.

Chip Ferrite Bead Feature Summary

• High current handling capability suitable for power line filtering
• Automotive-grade reliability with AEC-Q200 qualification
• Low DC resistance for minimal signal loss in power paths

Chip Ferrite Bead Applications

• Automotive electronic systems requiring high reliability
• Industrial equipment power supply filtering
• Medical equipment EMC suppression
• Mobile device power line noise reduction

Chip Ferrite Bead Procurement Notes

Verify the specific ordering suffix to ensure correct packaging format, such as tape and reel or cut tape, as these affect handling but not electrical function. Confirm AEC-Q200 qualification status if automotive application is required. Check RoHS3 compliance documentation for regulatory adherence. Ensure the manufacturer part number matches exactly to avoid substitution errors with similar impedance values.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity up to 6A is required in a compact 0805 footprint. The 25 Ohm impedance at 100 MHz targets specific EMI frequencies. Consider the low DCR of 4 mOhms for efficiency in power delivery networks. Verify thermal performance within the -40°C to +125°C range for the target environment. Compare against alternative part numbers like LSMCC201208T250NG for pin-compatible options.
