GUS-QS0B-03-8251-D Description

The GUS-QS0B-03-8251-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 8.25KΩ resistance value and a tight 0.5% 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 1W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust reliability in compact designs. Its gull-wing termination ensures secure PCB mounting, while the QSOP package (8.66mm x 6.02mm x 1.47mm) optimizes board space efficiency.
