GUS-QS8A-03-1693-FB Description

The GUS-QS8A-03-1693-FB from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Packaged in a 16-pin QSOP with gull-wing surface-mount terminals, it offers a 169K Ohm resistance per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation and 0.1W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The isolated (ISOL) circuit design ensures minimal crosstalk between resistors, while the 100V maximum voltage rating enhances versatility in high-voltage circuits.
