Fullerton, Calif. — TT electronics BI Technologies is offering its thin-film resistor networks on both silicon and ceramic substrates. The S Series precision resistor networks are constructed using a silicon substrate, while the Model 660 precision thin-film networks use a ceramic substrate. Both families feature isolated and bussed circuits along with a unique passivation coating to eliminate moisture concerns.

Typical applications include instrumentation amplifiers, precision voltage dividers, precision analog circuits, measurement bridge and low noise circuitry, ladder networks and converter applications.

The S Series networks feature a resistance range from 1 Kohm (Ω) to 100 KΩ for the isolated networks and 1 KΩ to 30 KΩ for the bussed networks. Ratio tolerance is less than &plumsn;0.05% with temperature coefficient of resistance (TCR) tracking tolerances of less than ±5 ppm/°C. The operating temperature ranges from -55°C to +125°C.

The Model 664, 667 and 668 networks feature a resistance range of 1 KΩ to 100 KΩ. Absolute tolerances at 25°C are to ±0.1% with TCR tracking to ±5 ppm/°C. The operating temperature ranges from -55°C to +125°C.

Pricing: Typically starts at $0.75 each in quantities of 1,000.
Availability: Lead times are from 12 to 14 weeks.
