GUS-QS0B-03-1212-CB Description

The GUS-QS0B-03-1212-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 12.1KΩ resistance value with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. Housed in a 20-pin QSOP package with gull-wing terminations, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch, making it ideal for high-density PCB designs. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this non-automotive, non-PPAP compliant component is optimized for precision analog and digital circuits.
