GS4A031540GFT Description

The GS4A031540GFT 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 154Ω resistance and a tight ±2% absolute tolerance (with ±1% ratio tolerance). Its ±25ppm/°C temperature coefficient ensures stable performance across a wide operating range of -70°C to +125°C. The SOIC package (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations enables reliable surface-mount assembly, while the ceramic construction enhances durability and thermal stability. Rated for 100V maximum voltage and 0.1W per resistor (0.4W total), it is ideal for high-density circuits demanding precision and reliability.
