GUS-QS8A-03-68R0-FF Description

The GUS-QS8A-03-68R0-FF from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications in surface-mount circuits. Featuring a 68Ω resistance value with a tight 1% tolerance, this thin-film resistor network delivers exceptional stability with a low ±25ppm/°C temperature coefficient. Encased in a 16-pin QSOP (QSOP-16) package, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) with gull-wing terminations for reliable SMD assembly. Rated for 0.75W total power dissipation (0.1W per resistor) and 100V maximum voltage, it operates across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The isolated (ISOL) circuit design ensures independent resistor performance, critical for signal integrity.
