Historically, combining both high-speed AC and precision DC measurement capability within an automated test system required mechanical relays to keep the two subsystems from interfering with each ...
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.
A thin coating of a composite made from zinc ferrite and polyaniline absorbs microwave radiation in Ku band, according to researchers at Anhui University of Science and Technology in China. The ...
