GS4B014992GDT Description

The GS4B014992GDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. This 8-pin narrow SOIC (SOIC-C series) device integrates 7 bussed resistors with a 49.9KΩ resistance value, offering an absolute tolerance of ±2% and a ratio tolerance of ±0.5%. Built with thin-film technology, it ensures stable performance across a wide temperature range of -70°C to +125°C, supported by a low temperature coefficient of ±100ppm/°C. The SOIC package (4.9mm x 5.99mm x 1.45mm) features gull-wing terminations for reliable surface-mount assembly, with a power rating of 0.4W total (0.05W per resistor). Its 100V maximum voltage rating and ceramic case enhance durability in harsh environments.
