GS4A031181FFT

GS4A031181FFT Description

The GS4A031181FFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 1.18 kΩ resistance and a tight ±1% absolute tolerance. The network operates within a wide temperature range of 70°C to 125°C, derated for optimal performance, and offers a low temperature coefficient of ±25 ppm/°C, ensuring stability under thermal stress. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this component is engineered for reliability in demanding environments. Its gull-wing termination and surface-mount design facilitate easy integration into compact PCB layouts.
