The CT40x product line features contact and contactless current sensors based on XtremeSense® TMR
CT403x and CT402x contact sensors are available in SOIC-8 and SOICW-16 package options featuring up to 5kV isolation voltage. The TMR sensor is differential which enables common-mode field rejection to cancel out stray magnetic fields. The primary conductor is only 0.5 mOhm which enables the sensor to withstand high in-rush current and minimize power loss.
CT4051 and CT4052 are contactless, coreless, non-intrusive XtremeSense® TMR based current sensor. Both are suitable in applications that require measuring high currents >100A and/or application that require high galvanic isolation. CT4052 is also a differential sensors which enables contactless current sensing without external shielding.
