GS4A031270GDT Description

The GS4A031270GDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 127Ω resistance and a tight ±2% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations offers robust surface-mount compatibility, while the 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision circuits.
