GS7A011873GT

GS7A011873GT Description

The GS7A011873GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 14-pin narrow SOIC package features 7 isolated thin-film resistors, each with a 187KΩ resistance and a tight ±2% tolerance. The device operates within a wide temperature range of 70°C to 125°C, derated for optimal performance, and offers a ±100ppm/°C temperature coefficient, ensuring minimal resistance drift. 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 gull-wing termination and surface-mount design facilitate easy integration into compact PCB layouts.
