GS4A032802GT

GS4A032802GT Description

The GS4A032802GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 28KΩ resistance and a tight ±2% tolerance. Its ±25ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. Encased in a rectangular ceramic SOIC package, the network offers excellent thermal stability and durability, with a 0.1W power rating per resistor (0.4W total). The gull-wing termination and 1.27mm terminal pitch facilitate easy surface-mount assembly, while its compact dimensions (4.9mm x 5.99mm x 1.45mm) make it ideal for space-constrained designs.
