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 ...
The small black cylinder near the end of many power and data cables is not a decorative lump of plastic, it is a deliberate piece of engineering that keeps your gadgets talking clearly in a noisy ...
If you ever see a small black cylindrical thing that looks like a lump sticking to the cable of your phone or laptop charger and wonder what it is for, then know that most people simply ignore it or ...
That little plastic cylinder at the end of a cable isn't there just to get in your way, it actually serves a purpose. Though we live in an age when cybercriminals can install microcomputers in iPhone ...
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.
