GQ8B014990GT Description

The GQ8B014990GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 499 Ohm resistance and a tight 2% tolerance. Built on a ceramic substrate, it offers excellent thermal stability and reliability, with a temperature coefficient of ±100ppm/°C. The network operates over a wide temperature range of 70°C to 125°C and delivers a total power rating of 0.75W (3/4W), with 0.05W (1/20W) per resistor. Its gull-wing termination and surface-mount design ensure easy PCB integration, while the 100V maximum voltage rating makes it suitable for robust circuit designs. Packaged in a tube, this non-automotive and non-PPAP compliant component is ideal for industrial and commercial electronics.
