That small black lump on your charger cable is a ferrite bead, a vital component that filters out electrical noise. This ...
The small black cylinder near the end of many power and data cables is not a decorative lump of plastic, it is a deliberate ...
Ferrite beads (L1 in the photo) filter high frequency power supply noise by converting it into a tiny amount of heat. Power supply noise can cause various problems for many parts, especially in analog ...
Dave (Dave Ritter): Oh, hi, Dr. T, I've got some shopping to do. My wife's an avid beader and I've got to sort through all this beading paraphernalia to find the perfect gift. Dave:Exactly! She weaves ...
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.
Radiation from hands-free mobile phones can be reduced to virtually zero by a simple tiny magnetic bead which costs a few pence, a government adviser says. Professor Lawrie Challis said clipping a ...
