FBMJ2125HS420-T Description

Short technical summary and product information.

FBMJ2125HS420-T is a surface-mount ferrite bead from Taiyo Yuden, designed for power line filtering in general electronic equipment. It offers 42 Ω impedance at 100 MHz with ±25% tolerance, making it suitable for suppressing high-frequency noise.

 

The component handles up to 4 A of DC current with a maximum DC resistance of only 8 mΩ, minimizing power loss. It operates over a wide temperature range of -40°C to +125°C, including self-generated heat. The ferrite bead is RoHS compliant, REACH compliant, and halogen-free.

 

This ferrite bead comes in a standard 0805 (2012 metric) EIA/JIS package with dimensions 2.0 mm × 1.25 mm × 0.85 mm. It is designed for surface mounting on printed circuit boards and supports both reflow and wave soldering. Terminal spacing is 0.5 mm.

 

Packaged in tape-and-reel with 4,000 pieces per reel, this component suits automated assembly in high-volume production. Its single-line filter structure is commonly used to reduce EMI in power supply lines.
