GUS-QS8A-03-1821-GF Description

The GUS-QS8A-03-1821-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 1.82KΩ resistance value per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm length × 6.02mm depth × 1.47mm height) and is supplied in a tube packaging for automated assembly. With a 0.1W (1/10W) power rating per resistor and a total power rating of 0.75W (3/4W), it balances power handling and space efficiency. The 100V maximum voltage rating and isolated circuit design (ISOL) make it suitable for high-reliability circuits.
