GS8B031502FDT Description

The GS8B031502FDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in a 16-pin narrow SOIC package, this bussed (BUS) configuration integrates 15 thin-film resistors, each rated at 15KΩ with ±1% absolute tolerance and ±0.5% ratio tolerance. The device operates over a wide temperature range of 70°C to 125°C (derated) and delivers a total power rating of 0.8W (0.05W per resistor). Its ±25ppm/°C temperature coefficient ensures stability in demanding environments, while the 100V maximum voltage rating and 1.27mm terminal pitch make it suitable for dense PCB layouts.
