Yageo metal current sensor product overview:Based on various applications, Yageo provides four solutions:1. Metal foil technology - PE series, resistance from 5m ohm to 910m ohm. PE has the widest size (0201 ~ 2512) and resistance range among all metal current sensor series. 2. Metal plate technology - PA series, rated power is up to 3W.3. Shunt resistor by welded technology – PU series (size 3921/5931), rated power is up to 10W. PU has excellent heat dissipation due to its central open-air design. Low thermal EMF feature can reduce the sensing error. 4. Metal current sensor with 4 terminals – PS series, PS has excellent heat dissipation and solderability. special 4 terminals design to separate current and voltage sensing positions can achieve high precision current sensing.

With these three technology, Yageo provdes complete size & resistance ranges to fullfill market demand in current sensing applications.
