SMD-resistor

A SMD-resistor which comprises a ceramic substrate having two main faces, two side faces and two end faces, and which further comprises two contact layers which are applied to two ends of one of said two main faces which adjoin the end faces, a resistive layer which is applied to said one main face and electrically contacts both contact layers, as well as two end contacts which cover the end faces of the substrate and which electrically contact the contact layers, characterized in that the end faces are intergranular fracture faces, in that the ceramic substrate is an alumina substrate comprising SiO.sub.2 and MO, where M stands for at least one element selected from the groups consisting of Ca, Sr and Ba and in that the SiO.sub.2 /Mo molar ratio is between 1 and 6.

A method of manufacturing a SMD resistor, said method comprising providing a ceramic substrate plate formed of a ceramic plate, which fractures to produce essentially only intergranular fracture faces, with first contact layers and resistive layers, electrically contacting first contact layers, on a main face of said plate, forming a first set of parallel fracture grooves in said plate forming a second set of parallel fracture grooves in said plastic extending substantially perpendicular to said first set of fracture grooves, fracturing said plate along said first set of fracture grooves to form bars having intergranular fracture faces, providing said fracture faces with second contact layers electrically contacting said first contact layers, and then fracturing said bars along said second set of fracture grooves to form individual SED resistors.
