Surface mount transformers sense current up to 20A

Surface mount transformers sense current up to 20A
Designed for load current measurement and control in switching power supplies and overload/short-circuit protection, a series of surface mount current sense transformers have been unveiled by Coilcraft. The CST7030 transformers measure just 5.2 X 7.0mm (with a maximum height of 3.0mm) and sense up to 20A of current at frequencies between 10kHz and 1MHz.

New battery reacts efficiently to extreme temperatures

New battery reacts efficiently to extreme temperatures
Stanford researchers are using spiky nanoparticles of graphene-coated nickel to create a lithium-ion battery that shuts down when it's too hot, then quickly restarts when it cools. The new technology could prevent the kind of fires that have prompted recalls and bans on a wide range of battery-powered devices, from computers to hoverboards.
