BI Technologies offers Sn/Pb versions of its thin film resistor networks that consist of S Series products which include isolated, bussed and voltage divider circuits. The networks also include NQSxx, 66x, 688 and 69x models in either isolated or bussed circuits. This line of thin film resistor networks is available on silicon or ceramic substrates that are offered in plastic or hermetically sealed packaging. The networks are offered with resistor counts from two to more than 30 per network. Resistance ranges from 10. to 100 KO with tolerance to ± 0.1% and ratio tolerance to ± 0.05%. The networks are available with TCRs to ± 25 ppm/° C and TCR tracking to ± 5 ppm/° C. Operating temperature ranges are from -55° C to +125° C.
