GUS-QS0B-03-2802-JF Description

The GUS-QS0B-03-2802-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 19-resistor array features a 28K Ohm resistance value per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. Housed in a compact 20-pin QSOP package with gull-wing termination, it offers a power rating of 1W (0.05W per resistor) and a maximum voltage rating of 100V. Its rectangular form factor (8.66mm x 6.02mm x 1.47mm) and 0.64mm terminal pitch make it ideal for high-density designs.
