GUS-QS0B-03-1241-JF Description

The GUS-QS0B-03-1241-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision surface-mount applications. This 19-resistor array features a 1.24KΩ resistance value per element 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 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. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it combines reliability with space efficiency.

GUS-QS0B-03-1241-JF Features
