GS4A026650GAT Description

The GS4A026650GAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 665Ω and a tight ±2% absolute tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating range of 70°C to 125°C, making it suitable for environments with fluctuating thermal conditions. The SOIC-C series construction offers excellent reliability, with a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances durability and thermal dissipation.
