Amorphous Block Cores Description
Amorphous Block Core is stacked by a 0.025mm amorphous ribbon and is designed for high power usage, easy to install, easy to wind copper wire. The laminations are bonded together by an adhesive rated for a continuous operating temperature of 155°C. Amorphous Block Cores have high saturation flux density, and low core loss. The amorphous core is suitable for solar inverter filter, medium frequency transformer, output inductor, and PFC coke. Size can be made according to the customer’s drawing.
