To better suit specific applications and requirements, the S Series precision resistor networks and the Model 660 thin-film resistor networks employ silicon and ceramic substrates, respectively, in their construction. Both feature isolated and bussed circuits along with a unique passivation coating to resist moisture. According to the company, ceramic substrates offer superior electrical properties and long-term stability while silicon provides more packaging options and a finer line width. Additional benefits for ceramic substrates include low parasitic losses, low NRE/NRT costs, and small minimum order quantities while silicon incurs a lower cost in high order quantities. The S Series networks provide a resistance range from 1 to 100 kOhms for the isolated networks and 1 to 30 kOhms for the bussed networks. Ratio tolerance is less than ±0.05% with TCR tracking tolerances of less than ±5 ppm/°C. Operating temperature ranges from -55°C to +125°C. The Model 664, 667, and 668 networks specify resistance values from 1 to 100 kOhms. Absolute tolerances at 25°C are to ±0.1% with TCR tracking to ±5 ppm/°C. Operating temperature ranges from -55°C to +125°C. Typical pricing for the thin film resistor networks starts at $0.75 each/1,000. BI TECHNOLOGIES, Fullerton, CA. (714) 447-2345.
