GS4A0227R0GDT Description

The GS4A0227R0GDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin Narrow SOIC package features four isolated thin-film resistors, each with a 27Ω resistance and a tight ±2% absolute tolerance. The device operates over a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in demanding environments. With a ±50ppm/°C temperature coefficient and a 0.4W total power rating (0.1W per resistor), it offers excellent stability and power handling. The SOIC package (4.9mm x 5.99mm x 1.45mm) includes gull-wing terminations for easy surface-mount assembly, making it ideal for automated PCB production.

GS4A0227R0GDT Features
