GQ8A0154R9GDT Description

The GQ8A0154R9GDT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Housed in a 16-pin QSOP ceramic package, it offers a 54.9Ω resistance per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient. The device operates over a wide temperature range (-70°C to +125°C) and delivers a total power rating of 0.75W (3/4W), with 0.1W (1/10W) per resistor. Its isolated (ISOL) circuit design ensures minimal crosstalk, making it ideal for signal integrity-critical systems. The gull-wing termination and surface-mount (SMD) compatibility facilitate easy PCB integration, while the ceramic case enhances thermal stability and durability.
