FBMH3216HM221NT8

Chip Ferrite Bead Overview

The FBMH3216HM221NT8 is a single-line ferrite bead chip from the FB series, manufactured by Taiyo Yuden. It operates within a temperature range of -40°C to +125°C and features a 1206 (3216 metric) surface-mount package with dimensions of 3.20mm x 1.60mm x 1.30mm maximum height. The component provides an impedance of 220 Ohms at 100 MHz with a tolerance of 30%. It supports a maximum DC current of 4A and has a maximum DC resistance of 20 milliohms. This part is AEC-Q200 qualified and RoHS3 compliant.

Chip Ferrite Bead Feature Summary

• Designed for power line applications to suppress electromagnetic interference
• High reliability suitable for automotive environments due to AEC-Q200 qualification
• Shielded construction minimizes external magnetic field interference

Chip Ferrite Bead Applications

• Automotive electronic systems requiring high-reliability EMI suppression
• Industrial equipment power circuits
• Medical equipment signal integrity protection

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'NT8' against official datasheets to confirm packaging type and reel specifications. Ensure compatibility with existing PCB footprint dimensions of 3216 metric. Confirm that the 4A current rating meets the design requirements for the target power line application without saturation issues.

Chip Ferrite Bead Selection Notes

Select this component when a 220 Ohm impedance at 100 MHz is required for power lines in space-constrained designs. The 1206 package offers a balance between current handling capability and board area efficiency. Consider the low DC resistance of 20 milliohms to minimize voltage drop and power loss in high-current paths compared to higher-resistance alternatives.

Chip Ferrite Bead Part Context

This ferrite bead belongs to Taiyo Yuden's FB series, which includes components optimized for automotive-grade applications. These products are manufactured in TS-16949 certified facilities using proprietary raw materials. The series is characterized by long lifetimes and low failure rates, making it suitable for harsh operating conditions found in automotive, industrial, and medical sectors.

Chip Ferrite Bead Replacement Considerations

FBMH3216HM221NT is a parameter-equivalent variant from the same manufacturer. LCMGA321616T221NG is listed as an alternate suggestion by distributors but requires verification of electrical equivalence.
