GQ8A031820FDT Description

The GQ8A031820FDT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Housed in a 16-pin QSOP ceramic package, it offers 182Ω resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. The isolated (ISOL) circuit design provides independent resistors, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it suits demanding environments. The gull-wing termination and surface-mount (SMD) design facilitate automated assembly.
