GQ8A018251BT Description

The GQ8A018251BT from TT Electronics/IRC is a high-precision, thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 8.25KΩ resistance value per resistor with an ultra-tight tolerance of ±0.1% and a low temperature coefficient of ±100ppm/°C, ensuring stable performance across a wide operating range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it ideal for high-reliability environments. The isolated (ISOL) circuit design ensures minimal crosstalk between resistors, while the gull-wing termination facilitates robust surface-mount assembly.
