GQ8A027872JT Description

The GQ8A027872JT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance values and robust thermal performance. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers a 78.7K Ohm resistance per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it is engineered for demanding circuits requiring isolation (ISOL) and minimal drift. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the ceramic construction enhances durability and heat dissipation.

GQ8A027872JT Features
