Abstract

This reports documents qualification tests made with the 100Ω PTC resistive composition DuPont (DP) 5092D, co-fired on the surface and inside (buried) DP 951 LTCC material, using a wide range of Ag & alloyed Ag-Pd conductor termination: DP 6142D & 6145 (Ag), and 6135D & 6143 & 6146 & 7484 (Ag-Pd). These tests were deemed necessary, as previous ones [1], carried out with Ag terminations only, were deemed not conclusive and reliable enough. The resulting resistors were electrically characterised, and the reliability of the different samples was analysed. Besides, the degree of deformation and morphology of the samples was qualitatively evaluated.

Surface

A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is the portion with which other materials first interact. The surface of an object is more than "a mere geometric solid", but is "filled with, spread over by, or suffused with perceivable qualities such as color and warmth".

Electrical element

In electrical engineering, electrical elements are conceptual abstractions representing idealized electrical components, such as resistors, capacitors, and inductors, used in the analysis of electrical networks. All electrical networks can be analyzed as multiple electrical elements interconnected by wires. Where the elements roughly correspond to real components, the representation can be in the form of a schematic diagram or circuit diagram. This is called a lumped-element circuit model.

Resistor

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls, in power distribution systems, or as test loads for generators.
