GUS-QS8A-03-3002-GA Description

The GUS-QS8A-03-3002-GA from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications. This thin-film resistor array features a 30K Ohm resistance per element with a tight 2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) and is supplied in tube packaging for automated assembly. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for demanding circuits requiring high isolation and low drift.
