GS4A0228R0GGT Description

The GS4A0228R0GGT 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 28Ω resistance and a tight ±2% absolute tolerance. The device operates within a wide temperature range of -70°C to +125°C, derated up to 125°C, and offers a ±50ppm/°C temperature coefficient, ensuring stability under thermal stress. With a 100V maximum voltage rating and 0.1W power dissipation per resistor (0.4W total), it is engineered for reliability in demanding circuits. The gull-wing termination and surface-mount design (4.9mm x 5.99mm x 1.45mm) facilitate compact PCB integration.
