GUS-QS0B-03-2800-CB Description

The GUS-QS0B-03-2800-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 280Ω resistance value per resistor with an ultra-tight ±0.25% 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 terminations, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-density PCB designs. The non-automotive and non-PPAP compliant device is supplied in a tube packaging for efficient handling.
