GQ8B0251R0GT Description

The GQ8B0251R0GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount configurations. This 16-pin QSOP package integrates 15 resistors, each with a 51Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The ceramic case and gull-wing termination provide robust mechanical stability, while the thin-film technology delivers excellent thermal stability with a ±50ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power dissipation and 0.05W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for harsh environments.

GQ8B0251R0GT Features
