CQ-330x: World's smallest coreless current sensor corresponding to the safety standards

Tokyo Japan, December 9 2014, Asahi Kasei Microdevices Corporation (AKM) had launched CQ-330x lineups.

CQ-330x is a coreless open-type magnetic current sensor achieving both small package and high isolation voltage.

Space-saving VSOP package and high-sensitive, fast-response sensor IC are best suited to current detection of small inverter circuit.

Even though this small package, certification of IEC/UL safety standards will assure of the high-voltage usage for industrial application.
