GS4B0251R1JDT Description

The GS4B0251R1JDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed with thin-film technology on a ceramic substrate, it delivers stable 51.1Ω resistance per element with a tight ±5% absolute tolerance and ±0.5% ratio tolerance. The device operates over a wide temperature range (-70°C to +125°C) and features a ±50ppm/°C temperature coefficient, ensuring reliability in demanding environments. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design (4.9mm × 5.99mm × 1.45mm) facilitate automated assembly.
