Chip bead ferrites can be made more resistant to high current surges, write Würth Elektronik’s Markus Holzbrecher and Mohamed Koobar. Chip bead ferrites are sensitive to current peaks, which typically ...
Simple, two-terminal SMT (surface-mount-technology)-ferrite-bead components perform crucial functions in many systems. For example, one might suppress electromagnetic emissions from a power wire.
Manufacturers of electrical and electronic equipment regularly submit their products for EMI/EMC testing to ensure regulations on electromagnetic compatibility are met. Inevitably, some equipment will ...

Why do laptop chargers have cylinders? Understanding ferrite beads and electronic interference
The modern laptop is a marvel of compact engineering, yet its power cable often features a curious, bulky lump that seems almost out of place. Most users ignore this plastic-encased cylinder, assuming ...
A new family of high-current ferrite beads could improve electromagnetic-interference (EMI) suppression in densely packed power supplies without reducing efficiency or consuming scarce PCB space.
