GS4A032872JFT Description

The GS4A032872JFT 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 resistance value of 28.7KΩ and a ±5% absolute tolerance. The network boasts a ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. Encased in a rectangular ceramic SOIC package, it offers excellent thermal and mechanical durability, with a 0.4W total power rating (0.1W per resistor). Its 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.
