Goodbon GBT-mZORB™ TW1000/2000/3000 series materials have the properties of high permeability and high magnetic loss. Working frequency range covers from 100K to 8GHz. Substrate resin is filled with high loss absorbent and metal molecules. Molecules are re-arranged in order by special process. This engineered material can restrain EMI waves bouncing back and forth. Noises then are converted to heat. This creates a clean EMI environment while maintaining electronic system normal operation.
