GQ0A0149R9GT

GQ0A0149R9GT Description

The GQ0A0149R9GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package features 10 isolated resistors, each with a 49.9Ω resistance, 2% tolerance, and a ±100ppm/°C temperature coefficient. Encased in a ceramic substrate, it offers superior thermal stability and durability. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of 70°C to 125°C. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the 0.64mm terminal pitch facilitates high-density PCB layouts. Packaged in a tube, it is ideal for automated manufacturing processes.
