GUS-QS8A-01-4121-GB Description

The GUS-QS8A-01-4121-GB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 4.12KΩ resistance value with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) ideal for space-constrained designs. The 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for moderate-power applications, while its 100V maximum voltage rating enhances reliability in high-voltage circuits.
