GQ8A037872FT Description

The GQ8A037872FT 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 78.7K Ohm 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 isolated (ISOL) circuit design allows independent resistor functionality, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Its 16-pin gull-wing SMD termination ensures reliable surface-mount assembly, and the ceramic substrate enhances thermal performance.
