    摘要: A variable impedance composition according to this aspect of the present invention comprises a conductive powder in an amount from 10% to 30% of the weight of the variable impedance composition, a semi-conductive power in an amount from 30% to 90% of the weight of the variable impedance composition, and an insulation adhesive in an amount from 3% to 50% of the weight of the variable impedance composition. According to one embodiment of the present invention, the variable impedance material presents a high resistance at a low applied voltage and a low resistance at a high applied voltage. As the variable impedance material is positioned in a gap between two conductors of an over-voltage protection device, the over-voltage protection device as a whole presents a high resistance to a low voltage applied across the gap and a low resistance to a high voltage applied across the gap.

    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.
