GQ8A033570CT Description

The GQ8A033570CT 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 357Ω resistance value per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and durability in harsh environments. The isolated (ISOL) circuit design allows independent resistor operation, making it ideal for precision voltage division and current sensing. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network balances power handling with compact surface-mount (SMD) gull-wing termination.
