GS4A0228R0GT

GS4A0228R0GT Description

The GS4A0228R0GT 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% tolerance. The device operates within a wide temperature range of 70°C to 125°C (derated) and offers a ±50ppm/°C temperature coefficient, ensuring stability under thermal stress. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, it is engineered for reliability in demanding circuits. The gull-wing termination and surface-mount design (SOIC package) facilitate easy PCB integration, while its ceramic case enhances durability and heat dissipation.

GS4A0228R0GT Features

• Isolated Resistors: Four independent 28Ω resistors with 2% absolute tolerance, ideal for signal isolation.
