GUS-QS8B-03-6191-C Description

The GUS-QS8B-03-6191-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 6.19KΩ resistance value and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads. Its gull-wing termination and compact dimensions (4.9mm x 6.02mm x 1.47mm) facilitate high-density PCB layouts.
