  • Chip resistor and method for the manufacture thereof
    Patent number: 4780702
    Abstract: A chip resistor having a value ranging from 10 Ohm to 100 kOhm and having a low temperature coefficient a low noise level and a high stability. The resistor is manufactured by means of the thin-fil technique. For this purpose, an NiCrAl-resistance layer is applied to one side of a flat ceramic support, and contact strips of Ni or an Ni-alloy, possibly preceded by an intermediate layer, are provided at two ends of the said support. An insulating lacquer layer is then applied to the resistance layer and partly overlaps the contact strips. The solderable supply strips are provided on the exposed metal portions.
