GUS-QS8A-03-2742-GF Description

The GUS-QS8A-03-2742-GF is a high-performance thin-film resistor network from TT Electronics/IRC, designed for precision applications requiring stable resistance values and tight tolerances. This 8-resistor isolated network features a 27.4K Ohm resistance per element with a 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm x 6.02mm x 1.47mm) ideal for space-constrained PCB designs. Rated for 0.75W total power dissipation (0.1W per resistor) and 100V maximum voltage, it operates reliably across a -70°C to +125°C temperature range. The non-automotive, non-PPAP compliant device is supplied in tube packaging for efficient assembly handling.
