Product Overview
The Vishay Dale ORN series resistor networks feature four isolated resistors with a standard 50 mil pitch lead spacing. These networks offer close TCR tracking and tight ratio tolerance, making them ideal for unity gain operational amplifier circuitry. They are available in a rugged molded case construction with no internal solder and a low temperature coefficient.
