GS4A0227R0GGT

GS4A0227R0GGT Description

The GS4A0227R0GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC package features four isolated 27Ω thin-film resistors with a tight ±2% absolute tolerance and ±2% ratio tolerance, ensuring consistent performance in matched circuits. Operating within a -70°C to +125°C temperature range, it delivers 0.1W power dissipation per resistor (0.4W total) and maintains stability with a low ±50ppm/°C TCR. The 100V maximum voltage rating and gull-wing termination make it suitable for robust surface-mount designs. Its ceramic substrate enhances thermal management and reliability in harsh environments.
