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 ...
Coilcraft offers a broad range of wirewound ferrite beads in standard package sizes from 0201 (0603) to 1812 (4532). Superior attenuation and frequency performance enable smaller solution sizes ...
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.
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 ...
