GUS-QS8A-03-2802-CB Description

The GUS-QS8A-03-2802-CB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package, it features 28K Ohm resistance per resistor with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The isolated (ISOL) circuit design allows independent resistor operation, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate robust PCB mounting.
