GQ8A034322FFT

GQ8A034322FFT Description

The GQ8A034322FFT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a ceramic QSOP package, it features 43.2KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The 16-pin gull-wing SMD termination facilitates reliable surface mounting, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its isolated (ISOL) circuit design provides flexibility in configurations, and the ceramic case enhances thermal and mechanical durability.
