GQ8A0168R1CT Description

The GQ8A0168R1CT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for isolation (ISOL) applications. Encased in a ceramic QSOP package, it offers a 68.1Ω resistance per element with an ultra-tight ±0.25% tolerance and a ±100ppm/°C temperature coefficient, ensuring stability across a wide temperature range (70°C to 125°C). The 16-pin gull-wing SMD configuration supports surface mounting, while its 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits.

GQ8A0168R1CT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy for sensitive analog/digital systems.
• Robust Ceramic Construction: Enhances thermal performance and durability in harsh environments.
