    • A film capacitor (10) in which a semiconductive layer (24) extends across the unmetallized margin (23) to provide a resistive path across the margin. The layer provides a parallel resistive path within the capacitor (10), itself, obviating the need for an external resistor. It also grades the electric field across the margin, i.e., makes the field more uniform, thus allowing the margin to be made narrower without electrical breakdown, permitting a reduction in the physical size of the capacitor (10). A refractory (19), semiconductive layer is provided between the metal layer (22), and the dielectric film (18). The refractory (19) layer accelerates the self-clearing process, by insulating the underlying dielectric film from the heat generated by the vaporizing metal, thus hastening vaporization and reducing the tendency of the dielectric film (18) to carbonize. As a result, faults are cleared with substantially less energy consumption. Preferably, the refractory layer (19) is also semiconductive, to reduce field emission effects, and thereby decrease the frequency of faults in the dielectric film (18).
    • 一种薄膜电容器(10),其中半导体层(24)延伸穿过未金属化的边缘(23)以提供跨越边缘的电阻路径。 该层在电容器(10)内提供并联电阻路径,本身不需要外部电阻器。 它还对跨越边缘的电场进行分级,即使场更均匀,从而允许使得边缘变窄得更窄,而不会发生电击穿,从而可以减小电容器(10)的物理尺寸。 在金属层(22)和电介质膜(18)之间设置耐火材料(19)半导体层。 耐火材料(19)层通过将下面的电介质膜与由汽化金属产生的热绝缘而加速自清洁过程,因此加速蒸发并降低电介质膜(18)碳化的趋势。 因此,能够消耗大量能量来清除故障。 优选地,耐火层(19)也是半导体的,以减少场致发射效应,从而降低电介质膜(18)中的故障频率。
