GS4B012702JT Description

The GS4B012702JT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision surface-mount applications. Built with ceramic substrate and thin-film technology, it offers a 27KΩ resistance per element with a ±5% tolerance and a ±100ppm/°C temperature coefficient. The device operates over a wide temperature range of -55°C to +125°C, with derated power handling up to 125°C. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. The gull-wing termination ensures reliable solder joints, while the SOIC package (4.9mm x 5.99mm x 1.45mm) provides space efficiency.
