GQ8A031072CBT Description

The GQ8A031072CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 10.7KΩ resistance value with an ultra-tight 0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic QSOP package, it offers 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-reliability circuits. The 16-pin gull-wing SMD termination ensures secure surface mounting, while its 100V maximum voltage rating and isolated (ISOL) circuit design enhance safety in sensitive applications.

GQ8A031072CBT Features

• Precision Thin Film Technology: Delivers ±25ppm/°C stability and 0.25% tolerance for critical analog/digital systems.
• Robust Ceramic Construction: Ensures high thermal conductivity and durability in harsh environments.
• Compact QSOP Package: 4.9mm × 6.02mm footprint with 1.47mm profile, ideal for space-constrained PCBs.
