GUS-QS0B-03-1802-JF Description

The GUS-QS0B-03-1802-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 19-resistor array features a 18K Ohm resistance value per resistor with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 20-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) ideal for space-constrained designs. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it combines reliability with efficiency. The non-automotive, EAR99-classified device is supplied in tube packaging, making it suitable for industrial and commercial applications.
