GUS-QS8A-03-1540-FD Description

The GUS-QS8A-03-1540-FD 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 features 8 isolated resistors, each with a 154 Ω resistance value and a tight 1% tolerance. The network operates within a wide temperature range of -70°C to +125°C, ensuring stability in demanding environments. With a power rating of 0.75W (3/4W) total and 0.1W (1/10W) per resistor, it balances compactness with robust power handling. The ±25ppm/°C temperature coefficient guarantees minimal resistance drift, critical for precision analog and digital circuits.
