GUS-QS8A-03-1200-FD Description

The GUS-QS8A-03-1200-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 120Ω resistors with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in demanding circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the compact 4.9mm × 6.02mm × 1.47mm footprint optimizes board space.
