GS4A039102JFT Description

The GS4A039102JFT 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 91kΩ resistance and a ±5% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures stability across a wide operating 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 terminations for reliable surface-mount assembly. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this network balances performance and durability.
