GUS-QS8B-01-4122-JG Description

The GUS-QS8B-01-4122-JG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 41.2K Ohm resistance value and a tight 5% tolerance, ensuring consistent performance across demanding circuits. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it balances power handling with compactness. The device operates over a wide temperature range of 70°C to 125°C (derated) and withstands up to 125°C maximum, making it suitable for industrial and automotive-adjacent environments. Its ±100ppm/°C temperature coefficient ensures stability under thermal stress, while the 100V maximum voltage rating adds robustness.
