GS4B011211BAT

GS4B011211BAT Description

The GS4B011211BAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC (SOIC-C Series) component features 7 bussed resistors with a 1.21 kΩ resistance value and an exceptional ±0.1% absolute tolerance, ensuring superior accuracy in circuit designs. Its thin-film technology and ±100 ppm/°C temperature coefficient provide stable performance across a wide temperature range (70°C to 125°C). With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this network is engineered for reliability in precision analog and digital systems. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case ensures durability and thermal stability.
