GUS-QS8A-03-4990-JA Description

The GUS-QS8A-03-4990-JA from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications in surface-mount circuits. This 16-pin QSOP package features 499Ω resistors with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable power handling in compact designs. The isolated (ISOL) circuit design allows for independent resistor operation, while the 100V maximum voltage rating and gull-wing termination ensure robust connectivity in demanding environments. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for industrial and commercial electronics.
