GQ8A0164R9FT Description

The GQ8A0164R9FT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for isolation (ISOL) applications. Housed in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact 4.9mm × 6.02mm × 1.47mm footprint, making it ideal for space-constrained PCB designs. Each resistor features a 64.9Ω value with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The ceramic case provides excellent thermal stability, while the 0.1W (1/10W) per resistor and 0.75W (3/4W) total power rating suit moderate-power applications.
