GS4A034120JAT Description

The GS4A034120JAT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 412Ω resistance and a ±5% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures stability across a wide operating range (70°C to 125°C), while the 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for demanding circuits. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations enables reliable surface-mount assembly.

GS4A034120JAT Features

• Isolated Resistors: Four independent 412Ω resistors with ±0.05% ratio tolerance, ideal for differential signal processing.
• High Stability: Thin-film technology and ±25ppm/°C TCR ensure minimal drift under thermal stress.
