GS4A037502FT

GS4A037502FT Description

The GS4A037502FT 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 75 kΩ resistance and a tight ±1% tolerance. The network operates within a wide temperature range of -70°C to +125°C, with a ±25 ppm/°C temperature coefficient, ensuring stability under thermal stress. Encased in a rectangular ceramic SOIC package, it offers a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, making it suitable for demanding environments. The gull-wing termination and 1.27mm terminal pitch facilitate reliable surface-mount assembly.
