GS4A031872FT Description

The GS4A031872FT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 18.7 kΩ and a tight ±1% tolerance. The network operates over a wide temperature range of -70°C to +125°C, with a ±25 ppm/°C temperature coefficient, ensuring stable performance under thermal stress. Encased in a rectangular ceramic SOIC package, it offers excellent durability and thermal conductivity. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this component is ideal for precision analog and digital circuits requiring reliable signal conditioning or voltage division.
