GQ8A032872GBT Description

The GQ8A032872GBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 8-resistor isolated network features a 28.7K Ohm resistance per element with a tight 2% tolerance and an ultra-low ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it suitable for demanding environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating ensure robust handling of distributed loads.
