GQ8A039760CAT Description

The GQ8A039760CAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit isolation (ISOL) applications. This 8-resistor array features a 976Ω resistance value with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability environments. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal performance.
