GUS-QS0B-03-7872-JA Description

The GUS-QS0B-03-7872-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors with a 78.7K Ohm resistance value and a tight ±5% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of -70°C to +125°C. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Packaged in a tube for automated assembly, its gull-wing termination and compact dimensions (8.66mm x 6.02mm x 1.47mm) optimize PCB space utilization.
