GUS-QS0B-03-5490-GA Description

The GUS-QS0B-03-5490-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 19-resistor array features a 549Ω resistance value per resistor with a tight 2% 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 (Quarter Small Outline Package) with gull-wing SMD termination, it offers a compact footprint (8.66mm x 6.02mm x 1.47mm) ideal for space-constrained PCB designs. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding analog and digital circuits.

GUS-QS0B-03-5490-GA Features
