GQ8A0143R2DT

GQ8A0143R2DT Description

The GQ8A0143R2DT 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 43.2Ω resistance value per element with a tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers superior 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 (SMD) assembly. With a 0.75W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network balances power handling with precision.
