GS7B031502DDT Description

The GS7B031502DDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance across a wide temperature range. Housed in a 14-pin narrow SOIC package, this bussed network integrates 13 thin-film resistors, each with a 15KΩ resistance and an absolute tolerance of ±0.5%. The device operates over a temperature range of 70°C to 125°C with a low temperature coefficient of ±25ppm/°C, ensuring minimal resistance drift. Its 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The SOIC-C series construction features a rectangular ceramic case, gull-wing termination, and surface-mount compatibility, offering robust mechanical and thermal stability.
