    Abstract: A porous carbon has an ID/IG of 2.0 or more in a Raman spectrum measured by Raman spectroscopy with respect to the porous carbon wherein the IG is an accumulated intensity of a peak for G band around 1590 cm−1, and the ID is an accumulated intensity of a peak for D band around 1350 cm−1. The porous carbon has pores having a size of less than 1 μm. The porous carbon can be contained in a resin composition for producing a varistor element.

    Abstract: A varistor has a disc of ceramic material having opposed faces with face edges. There is an electrode on each face with a gap between each electrode and the edge of the face. Glass passivation is on at least one face in the gap, the passivation not extending from one electrode to the other electrode around the surface of the disc. Because the passivation is only on the planar opposed disc faces, it may be applied in a simple operation such as screen printing. Indeed, the screen printing may be performed while the discs are in the same nest plates as are used for printing of electrode paste. Even though the passivation does not extend from one electrode to the other, it nevertheless breaks a potentially conductive path between the electrodes caused by interaction between the ceramic and encapsulant materials.

    Abstract translation: 变阻器具有具有面边缘的相对面的陶瓷材料盘。 每个面上都有一个电极，每个电极和面部边缘之间都有间隙。 玻璃钝化在间隙中的至少一个面上，钝化不会从一个电极延伸到围绕盘表面的另一个电极。 因为钝化仅在平面相对的盘面上，所以可以在诸如丝网印刷的简单操作中施加钝化。 实际上，可以在盘与用于印刷电极浆料时相同的嵌板中进行丝网印刷。 即使钝化不从一个电极延伸到另一个电极，但是它仍然破坏由陶瓷和密封剂材料之间的相互作用引起的电极之间的潜在传导路径。

    Abstract: Disclosed is a variable voltage protection device for electronic devices which in one aspect comprises a thin layer of neat dielectric polymer or glass positioned between a ground plane and an electrical conductor for overvoltage protection, wherein the neat polymer or glass layer does not include the presence of conductive or semiconductive particles. Also disclosed is the combination of the neat dielectric polymer or glass thin layer positioned on a conventional variable voltage protection material comprising a binder containing conductive or semiconductive particles. A multi-layer variable voltage protection component is disclosed comprising three layers of overvoltage protection material wherein the outer two layers contain a lower percentage of conductive or semiconductive particles and wherein the inner layer contains a higher percentage of conductive or semiconductive particles. The multi-layer component can optionally be used in combination with the neat dielectric polymer or glass layer and can optionally have interposed metal layers. A method is disclosed for dispersing insulative particles and conductive or semiconductive particles in a binder using a volatile solvent for dispersement of the insulative particles and the conductive or semiconductive particles before mixing with the binder.
