US 5,142,430 A · Power line filter and surge protection circuit components and circuits

Abstract

The invention is directed to power line filter and surge protection circuit components and the circuits in which they are used to form a protective device for electrical equipment. The circuit components comprise wafers or disks of material having desired electrical properties such as varistor or capacitive characteristics. The disks are provided with electrode patterns on surfaces thereof which coact with apertures formed therein so as to electrically connect the components to electrical conductors of a system easily and effectively. The electrode patterns act in conjunction with one another to form common electrodes with the material interposed therebetween. The electrode patterns are optimized in the circuit components such that balanced protection is achieved over all electrical conductors. The components also eliminate the use of leads such that operating characteristics are improved significantly. The invention provides an easily manufactured and cost effective construction usable in a variety of applications.
