GS4A021243FBT Description

The GS4A021243FBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 124KΩ and an absolute tolerance of ±1%. The network operates within a temperature range of 70°C to 125°C, with a derated power rating of 0.1W per resistor (0.4W total). Its ±50ppm/°C temperature coefficient ensures stability across varying thermal conditions, while the 100V maximum voltage rating makes it suitable for high-voltage circuits. Encased in a rectangular ceramic SOIC package, it offers excellent thermal and mechanical durability.
