GUS-QS0B-03-2490-FC Description

The GUS-QS0B-03-2490-FC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 19-resistor array features a 249Ω resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Packaged in a 20-pin QSOP 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 precision in a tube-packaged, non-automotive solution.
