GUS-QS0B-03-6650-D Description

The GUS-QS0B-03-6650-D 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 665 Ω resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25 ppm/°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 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust reliability in compact designs. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB assembly, while the 1.47mm low-profile height optimizes space-constrained layouts.
