GQ8B014991DT Description

The GQ8B014991DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 4.99KΩ resistance value, offering a tight ±0.5% tolerance and a low ±100ppm/°C temperature coefficient. Encased in a ceramic package, it ensures superior thermal stability and reliability across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.05W per resistor, it balances performance and power dissipation efficiently. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating makes it suitable for high-voltage circuits.
