GS8A021802GT

GS8A021802GT Description

The GS8A021802GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-resistor network features an 18K Ohm resistance per element with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a ceramic SOIC-16 package, it offers excellent thermal stability and mechanical durability. The isolated (ISOL) circuit design allows independent resistor operation, making it ideal for signal conditioning and voltage division in complex circuits. With a 0.8W total power rating (0.1W per resistor) and a 100V maximum voltage rating, it suits moderate-power applications. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the ±0.1mm dimensional tolerances facilitate precise PCB placement.
