GS4A0127R0FFT

GS4A0127R0FFT Description

The GS4A0127R0FFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 27Ω resistance 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, making it suitable for demanding environments. Its ±100ppm/°C temperature coefficient ensures minimal resistance drift, while the 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) provide reliable operation in circuit isolation and signal conditioning applications. The gull-wing termination and surface-mount design facilitate easy PCB integration.
