GQ8B0257R6FFT Description

The GQ8B0257R6FFT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter-Small Outline Package) device integrates 15 resistors with a 57.6Ω resistance value, offering 1% tolerance and a ±50ppm/°C temperature coefficient for stable performance across a -70°C to +125°C operating range. Encased in a ceramic package, it delivers 0.75W (3/4W) total power dissipation (0.05W per resistor), with a 100V maximum voltage rating. Its gull-wing termination and surface-mount design ensure reliable PCB integration, while the ±0.1mm dimensional tolerances enhance placement accuracy.
