GUS-QS0B-03-8451-FC Description

The GUS-QS0B-03-8451-FC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. It features 19 resistors in a 20-pin QSOP package with a compact footprint (8.66mm × 6.02mm × 1.47mm), making it ideal for space-constrained PCB designs. Each resistor offers a 8.45KΩ value with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. The network supports a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, with gull-wing terminations for reliable solderability. Packaged in a tube, this non-automotive, non-PPAP compliant component is suited for industrial and commercial electronics.
