GQ0A031240GDT Description

The GQ0A031240GDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP device features 10 isolated resistors, each with a 124 Ω resistance value and a tight 2% tolerance. Encased in a ceramic package, it offers excellent thermal stability and durability, with a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) compatibility, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift across a wide 70°C to 125°C derated power range. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is ideal for demanding circuits requiring isolation and precision.
