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 ...

This article covers chip ferrite beads used in DC power lines. Even if a datasheet states "X ohms at 100MHz," if the noise you want to suppress is at a different frequency, that single number alone ...

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 ...

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 ...

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.

DALLAS, Oct. 21, 2020 /PRNewswire/ -- Texas Instruments (TI) (Nasdaq: TXN) today introduced a new family of low-noise DC/DC switching regulators with integrated ferrite-bead compensation. The TPS62912 ...

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 ...

All the components of your devices have some purpose or the other. Sometimes you know it, though at times, you are not aware of the purpose. Hence, no matter how weird a part appears, there is always ...
