GQ8A031872GBT Description

The GQ8A031872GBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and tight tolerances. This 8-resistor network features an 18.7K Ohm resistance per element with a 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (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 isolated (ISOL) circuit design ensures minimal crosstalk between resistors, while the gull-wing termination facilitates easy surface-mount (SMD) assembly.
