GS4A012742FT Description

The GS4A012742FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features 27.4KΩ resistance per element with a tight ±1% tolerance and a low ±100ppm/°C temperature coefficient. Its thin-film technology ensures stable performance across a wide temperature range (70°C to 125°C derated, 125°C max). The device offers a 0.1W power rating per resistor (0.4W total) and supports 100V maximum voltage, making it suitable for high-reliability circuits. With a compact 4.9mm × 5.99mm × 1.45mm footprint and gull-wing termination, it is optimized for surface-mount assembly.
