Vishay Extends MPM/ORN Series Resistor Networks

June 15, 2004 by Jeff Shepard

Vishay Intertechnology Inc. (Malvern, PA) announced two new precision thin-film resistor networks that extend the ratio tolerance of the company's MPM and ORN matched-pair and quad-resistor networks to a new industry low of just 0.01% in standard molded SOT-23 and eight-pin SOIC packages. Intended for use in instrumentation amplifiers, precision voltage dividers and bridge network circuitry, the devices provide an alternative to technologies such as wirewound or hermetic packaging.

In addition to being precision-matched to 0.01% ratio tolerance for like resistance values, the MPM Series feature temperature coefficient ratio tracking (TCR) of ±2 ppm/°C and provide stability for all surface-mount applications. The ORN family features four isolated resistors with standard 50 mil pitch lead spacing. With close TCR tracking of ±5 ppm/°C and tight ratio tolerance down to 0.01%, the ORN devices are suited for unity gain operational amplifier circuitry.

Samples and production quantities of the new devices are available now, with a lead time of two to six weeks for larger orders. Pricing for US delivery is $2.37 per piece for matched pair types.
