GS4A031581JBT Description

The GS4A031581JBT 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 1.58KΩ and a tolerance of ±5%. The network operates within a temperature range of 70°C to 125°C, with a ±25ppm/°C temperature coefficient, ensuring stability under varying thermal conditions. Encased in a rectangular SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. Rated for 100V maximum voltage and 0.1W power per resistor, it is ideal for high-density PCB designs requiring consistent performance.
