GUS-QS8B-03-4221-J Description

The GUS-QS8B-03-4221-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 4.22KΩ resistance value and a tight ±5% tolerance. The network operates over a wide temperature range of 70°C to 125°C (derated) and can withstand 125°C maximum operating temperature, making it suitable for demanding environments. With a ±25ppm/°C temperature coefficient, it ensures stable performance under thermal fluctuations. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust electrical characteristics for industrial and commercial circuits.
