GQ0A0278R7JFT Description

The GQ0A0278R7JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 20-pin QSOP package integrates 10 isolated resistors, each with a 78.7Ω resistance, 5% tolerance, and a ±50ppm/°C temperature coefficient, ensuring consistent performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical and electrical stability, making it suitable for surface-mount (SMD) applications in demanding environments. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is ideal for circuits requiring high-density, low-noise resistance solutions.

GQ0A0278R7JFT Features
