Description
The shield is designed for PCB-based planar current sensing in combination with a magnetic field sensor, i.e., Hall sensor, AMR sensor and a current conductor. The UCR-shields the sensor from parasitic magnetic fields caused by nearby conductors or other magnetic field sources while at the same time it enhances sensitivity and signal-to-offset ratio of the sensor.
