GS4A031473GBT Description

The GS4A031473GBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 147 kΩ and a tight ±2% absolute tolerance (with ±0.1% ratio tolerance). The device operates over a wide temperature range of 70°C to 125°C, with a ±25 ppm/°C temperature coefficient, ensuring stability in fluctuating thermal conditions. Its SOIC-C series construction provides robust performance with a 0.1W power rating per resistor (0.4W total), housed in a rectangular ceramic case for enhanced durability. Rated for 100V maximum voltage, this network is ideal for precision analog and digital circuits requiring reliable isolation and minimal drift.
