The RC-­chamber is a soft ferromagnetic chamber featuring superior material characteristics such as high linearity, very low hysteresis, and high magnetic permeability.


The shield is designed for protecting sensitive circuits from unwanted parasitic magnetic fields. Applications include power inverters, magnetic position and current sensors magnetic immunity, and EMI.
