Laminated U-Shield Ni-Fe or Si-Fe Soft Ferromagnetic Shield

Description

This soft ferromagnetic core is featuring superior material characteristics such as high linearity and very low hysteresis. The core is designed to achieve linearity for very high current with minimum footprint. Furthermore the core protects the sensor from parasitic magnetic fields caused by nearby conductors or other magnetic field sources. They are widely used in BMS, EV motor controller and inverter applications. These parts are a stack of lamination which allows the core to handle high frequency currents. They can be made in customer specific thicknesses by using different numbers of lamination.
