GQ8A031200DT Description

The GQ8A031200DT 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 120Ω resistance value per element with an ultra-tight 0.5% 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 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-density PCB designs. The gull-wing termination and 0.64mm pitch enable reliable surface-mount assembly, while its 100V maximum voltage rating and isolated (ISOL) circuit design enhance signal integrity in noisy environments.

GQ8A031200DT Features

• Precision Thin Film Technology: Delivers ±25ppm/°C TCR and 0.5% tolerance for critical analog/digital circuits.
• Robust Ceramic Package: Ensures thermal stability and mechanical durability in harsh conditions.
• High Power Handling: 0.75W total (0.1W per resistor) with derating up to 125°C.
