GS8B019090DBT Description

The GS8B019090DBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding surface-mount applications. Housed in a 16-pin narrow SOIC (SOIC-C) package, it features 15 bussed (BUS) thin-film resistors with a 909Ω resistance value and an absolute tolerance of ±0.5%, ensuring exceptional accuracy. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, making it suitable for harsh environments. Its ±100ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor (0.8W total) ensure stable performance under varying thermal conditions. The 100V maximum voltage rating and gull-wing termination further enhance reliability in compact PCB designs.
