GUS-QS8A-02-3012-JB Description

The GUS-QS8A-02-3012-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 30.1KΩ resistance value per resistor with a 5% tolerance, ensuring reliable performance in demanding circuits. Encased in a 16-pin QSOP (Quarter Small Outline Package), it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) with gull-wing terminations for secure surface-mount assembly. Rated for 0.75W (3/4W) total power dissipation and 0.1W per resistor, it operates across a wide temperature range of -70°C to +125°C, with a ±50ppm/°C temperature coefficient for stable resistance under thermal stress. Its 100V maximum voltage rating and isolated circuit design (ISOL) make it ideal for signal conditioning, voltage division, and impedance matching.
