GQ8A012552GGT Description

The GQ8A012552GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-resistor network features a 25.5K Ohm resistance per element with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range of 70°C to 125°C. Housed in a ceramic QSOP package with 16 gull-wing terminals, it offers excellent thermal dissipation and mechanical durability. The isolated (ISOL) circuit design allows for flexible configurations, while the 0.75W (3/4W) total power rating (0.1W per resistor) supports demanding circuit conditions.
