This application note provides guidelines for designing ferrite bead filter networks to isolate shared power rails of Stratix® IV FPGAs. Advancements in FPGA technology have increased data rates ...

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 ...

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 ...

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 ...
