GQ0A0249R9DT Description

The GQ0A0249R9DT 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 features 10 isolated resistors, each with a 49.9 Ω resistance, 0.5% tolerance, and a ±50 ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing termination and 0.64mm terminal pitch ensure compatibility with automated SMD assembly processes.
