GUS-QS8B-03-3161-B Description

The GUS-QS8B-03-3161-B is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding applications requiring tight tolerances and stable performance. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 3.16KΩ resistance value and an exceptional 0.1% tolerance, ensuring minimal deviation in critical circuits. The network operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, making it suitable for harsh environments. Its ±25ppm/°C temperature coefficient guarantees minimal resistance drift, while the 100V maximum voltage rating and 0.75W total power dissipation (0.05W per resistor) provide robust performance in compact designs.
