GQ8A012800DT Description

The GQ8A012800DT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for isolation (ISOL) applications. Housed in a 16-pin QSOP ceramic package, it features 280Ω resistance per element with an ultra-tight ±0.5% tolerance and ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The 0.75W (3/4W) total power rating and 0.1W per resistor make it suitable for power-sensitive designs, while its 100V maximum voltage rating and gull-wing SMD termination enable reliable surface mounting in compact PCB layouts. The ceramic case enhances thermal stability and durability, ideal for harsh environments.
