GQ0A021240DT Description

The GQ0A021240DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a 124 Ω resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±50 ppm/°C temperature coefficient guarantees stable performance across a wide operating range of 70°C to 125°C. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision analog and digital circuits.
