GS4A031540FCT Description

The GS4A031540FCT 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 resistance value of 154Ω and a tight ±1% absolute tolerance (with ±0.25% ratio tolerance). Its ±25ppm/°C temperature coefficient ensures stability across a wide operating range (70°C to 125°C), making it suitable for environments requiring consistent performance under thermal stress. The SOIC package (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations enables reliable surface-mount assembly, while the ceramic case enhances durability and heat dissipation. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, this network is ideal for analog signal conditioning, voltage division, and isolation circuits.
