摘要： A variable impedance composition according to one aspect of the present invention comprises a high electro-magnetic permeability powder in an amount from 10% to 85% of the weight of the variable impedance composition, and an insulation adhesive in an amount from 10% to 30% of the weight of the variable impedance composition. The incorporation of high electro-magnetic permeability powder including carbonyl metal, such as carbonyl iron or carbonyl nickel, in the variable impedance composition can not only suppress the overstress voltage, but also dampen the transient current. In contrast to the conventional electrostatic discharge (ESD) device, the relatively high electro-magnetic permeability carbonyl metal powder can reduce arcing as well as lower the trigger voltage of the device. The high electro-magnetic permeability characteristics can also absorb the undesirable electro-magnetic radiation that causes corruption of signal and loss of data.
