GQ8A028452GGT Description

The GQ8A028452GGT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications requiring stable resistance values and tight tolerances. Encased in a ceramic QSOP package, this surface-mount device (SMD) offers an 84.5K Ohm resistance per resistor with a 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (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, particularly those requiring isolation (denoted by the ISOL circuit designator). The 16-pin gull-wing termination ensures secure PCB mounting, while the ceramic construction enhances thermal and mechanical stability.
