GQ8A031580FDT Description

The GQ8A031580FDT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it features 158Ω resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The isolated (ISOL) circuit design eliminates crosstalk, making it ideal for signal integrity-critical systems. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances power handling and compactness in a 4.9mm × 6.02mm × 1.47mm surface-mount form factor. The 16-pin gull-wing termination ensures reliable solder joints in automated PCB assembly.
