GS4A023570FFT

GS4A023570FFT Description

The GS4A023570FFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors with a resistance value of 357Ω and a tight ±1% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in demanding environments. Its ±50ppm/°C temperature coefficient enhances stability, while the 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for low-power, high-precision circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration.
