GUS-QS8B-00-37R4-JG Description

The GUS-QS8B-00-37R4-JG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in compact surface-mount assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 37.4Ω resistance value and a 5% tolerance, delivering a total power rating of 0.75W (3/4W). The network operates over a wide temperature range of 70°C to 125°C (derated) and withstands up to 125°C at full load, making it suitable for demanding environments. Its ±250ppm/°C temperature coefficient ensures stable performance under thermal stress, while the 100V maximum voltage rating enhances reliability in high-voltage circuits.
