GS7B034020DCT

GS7B034020DCT Description

The GS7B034020DCT 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 (BUS) configuration integrates 13 thin-film resistors, each with a 402Ω 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 0.7W total power rating make it suitable for low-power circuits, while the 100V maximum voltage rating adds versatility. The SOIC-C series construction features gull-wing termination for reliable surface-mount (SMD) assembly, with tight dimensional tolerances (±0.1mm height, ±0.2mm depth).
