Title: Franz Zettl: Innovator in Electrical Components

Introduction

Franz Zettl is a notable inventor based in Deutschlandsberg, Austria. He has made significant contributions to the field of electrical components, holding 2 patents that showcase his innovative spirit and technical expertise.

Latest Patents

Zettl's latest patents include an electrical multilayer component comprising a sintered, monolithic ceramic body. This invention features cavities that are alternately open toward opposite end faces and are open to a slight portion of the lateral surfaces, which are at right angles to the end faces. The cavities contain ceramic particles that act as supporting elements and are completely filled with a filler metal. This metal has a melting temperature considerably lower than the sintering temperature of the ceramic body, allowing it to wet the surfaces of the ceramic layers in its molten state. Additionally, the edges between the six outside surfaces of the component are rounded off, ensuring that the metal fillings extend up to contact elements applied after the metal is introduced.

Another significant patent is for a voltage-dependent resistor, or varistor, composed of a monolithic ceramic body made up of multiple layers of varistor material containing zinc oxide. These layers alternate with layers of precious metal that serve as coatings and are electrically connected to separate locations on the exterior surfaces of the body. The porosity of the layers of varistor material does not exceed 5%, with the proportion of bismuth at most 1 mol %. The precious metal coatings include 50-80% by weight of palladium.
