GS8B021211DDT

GS8B021211DDT Description

The GS8B021211DDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying thermal conditions. Packaged in a 16-pin narrow SOIC (SOIC-C) format, this bussed network integrates 15 thin-film resistors, each with a 1.21 kΩ resistance and an absolute tolerance of ±0.5%. The device operates over a wide temperature range of 70°C to 125°C with a derated power rating, ensuring reliability in harsh environments. Its ±50 ppm/°C temperature coefficient minimizes resistance drift, while the 0.05W (1/20) power rating per resistor and 0.8W total power rating balance performance and thermal management. The 100V maximum voltage rating and gull-wing termination make it suitable for surface-mount applications requiring robust electrical characteristics.
