GS7A031473GGT

GS7A031473GGT Description

The GS7A031473GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. This 14-pin narrow SOIC package features 7 isolated thin-film resistors, each with a 147KΩ resistance and a tight ±2% absolute tolerance. The device operates within a wide temperature range of 70°C to 125°C (derated) and maintains a low temperature coefficient of ±25ppm/°C, ensuring minimal resistance drift under varying thermal conditions. With a maximum voltage rating of 100V and a power rating of 0.7W (0.1W per resistor), it is engineered for reliability in demanding circuits. The SOIC-C series construction offers a compact footprint (8.66mm × 5.99mm × 1.45mm) with gull-wing terminations for secure surface-mount assembly.
