GUS-QS0B-03-1051-JD

GUS-QS0B-03-1051-JD Description

The GUS-QS0B-03-1051-JD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. It features 19 resistors with a 1.05KΩ resistance value, 5% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 20-pin QSOP package with gull-wing SMD termination, this network offers a compact footprint (8.66mm x 6.02mm x 1.47mm) and 0.64mm terminal pitch, making it ideal for space-constrained PCB designs. With a 1W total power rating (0.05W per resistor) and 100V maximum voltage rating, it balances power handling with precision. The non-automotive, non-PPAP compliant device is supplied in tube packaging for ease of handling.
