GUS-QS8A-01-1821-GG Description

The GUS-QS8A-01-1821-GG from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a 16-pin QSOP package with gull wing termination, this surface-mount device offers a 1.82KΩ resistance per element with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range (-70°C to +125°C). The compact 4.9mm × 6.02mm × 1.47mm footprint and ±0.1mm height tolerance facilitate high-density PCB layouts.
