GS4B0251R0GGT Description

The GS4B0251R0GGT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable resistance values. Built with ceramic substrate and thin-film technology, it offers a 51Ω resistance per element with a tight ±2% absolute tolerance and ±2% ratio tolerance. The device operates over a wide temperature range (-70°C to +125°C) with a low ±50ppm/°C temperature coefficient, ensuring minimal drift under thermal stress. Rated for 100V maximum voltage and 0.4W total power dissipation, it combines reliability with compact surface-mount (SOIC) packaging (4.9mm x 5.99mm x 1.45mm).
