GUS-QS0B-02-1742-DB Description

The GUS-QS0B-02-1742-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 17.4KΩ resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C, making it suitable for harsh environments. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in high-density PCB designs. Packaged in a tube for automated assembly, this non-automotive, non-PPAP compliant component is ideal for industrial and instrumentation applications where precision and durability are critical.
