GUS-QS8B-03-3902-JG Description

The GUS-QS8B-03-3902-JG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device integrates 15 resistors, each with a 39K Ohm resistance value and a tight 5% tolerance. It operates within a wide temperature range of 70°C to 125°C (derated) and can withstand up to 125°C at full load, making it suitable for demanding environments. The network delivers a total power rating of 0.75W (3/4W) with 0.05W (1/20W) per resistor, ensuring reliable performance in compact designs. Its ±25ppm/°C temperature coefficient guarantees stability across thermal variations, while the 100V maximum voltage rating enhances durability in high-voltage circuits.
