In stock now at distributor Mouser Electronics, Inc. is the CT220 XtremeSense contactless current sensors from Crocus Technology.

These sensors are powered by Crocus' patented XtremeSense tunnel magneto-resistance (TMR) 1D technology, which enables them to detect slight changes in AC or DC current.

They offer a 2.7V to 5.5V supply voltage range and 1.2mA supply current rating in a five-lead SOT23 package.

CT220 sensors measure the magnetic field of the current flowing through a busbar or printed circuit board (PCB) trace and convert it to an analogue output voltage that represents the field and current.

They achieve XtremeSense performance with a typical total out error of ±0.5% while sensing field as low as 5mA.

An inherently high isolation, makes them an ideal solution for applications where product safety compliance is a requirement.

Applications for the Crocus CT220 sensors include motor controls, solar inverters, power distribution units and power supplies, and Internet of Things (IoT) devices.
