GS4A023902FT Description

The GS4A023902FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-pin narrow SOIC device features four isolated thin-film resistors, each rated at 39 kΩ with a tight ±1% tolerance and a low ±50 ppm/°C temperature coefficient, ensuring minimal drift across its operating range of 70°C to 125°C. Encased in a rectangular ceramic SOIC package, it offers superior thermal management and durability, with a maximum voltage rating of 100V and a total power dissipation of 0.4W (0.1W per resistor). Its gull-wing termination and 1.27mm terminal pitch facilitate reliable surface-mount assembly, while its compact dimensions (4.9mm x 5.99mm x 1.45mm) make it ideal for space-constrained designs.
