GS7B032942JDT Description

The GS7B032942JDT from TT Electronics/IRC is a high-performance 14-pin narrow SOIC ceramic resistor network designed for precision applications requiring stable resistance values and tight tolerances. This bussed (BUS) configuration device integrates 13 thin-film resistors, each with a 29.4KΩ resistance and an absolute tolerance of ±5%, ensuring consistent performance across all elements. The network operates within a wide temperature range of 70°C to 125°C (derated) and features a low temperature coefficient of ±25ppm/°C, minimizing resistance drift under thermal stress. Encased in a rectangular ceramic SOIC package, it offers robust mechanical stability and excellent thermal dissipation, with a maximum voltage rating of 100V and a total power rating of 0.7W (0.05W per resistor).
