GS4A031470FCT Description

The GS4A031470FCT 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 147Ω resistance and a tight ±1% absolute tolerance (with ±0.25% ratio tolerance). Its ±25ppm/°C temperature coefficient ensures stability across a wide operating temperature range of 70°C to 125°C, making it suitable for demanding environments. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint with gull-wing termination for reliable surface-mount assembly. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it combines durability with precision.
