The 0805 family is a series of common mode chokes designed for critical applications. It eliminates virtually all-common mode noise in high-speed, differential mode signal transmission applications ...

What that “mystery cylinder” actually is The black cylinder is usually a ferrite bead, sometimes called a ferrite block, ferrite core, ferrite ring, EMI filter, or ferrite choke, and it is made from a ...

Here's a simple DIY EMC measurement antenna that is adjustable from about 85 to 200 MHz (depending on the telescoping antennas used) and is small enough to throw into your EMC troubleshooting kit. It ...

Two new wideband shield bead ferrite chokes attenuate EMI and other unwanted signals in a circuit without contributing to power losses at lower frequencies or dc. Similar in performance to other SPG ...

Q Some USB cables have a bump on one end and others don’t. What does the bump do, and can I use bump and bumpless cables interchangeably? A The bump is mostly likely the cylindrical ferrite bead ...

Chokes help reduce EMI and save space, supporting high-voltage designs in power converters, motor drives, and power supplies.
