GS8A021473CT Description

The GS8A021473CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation applications. This 8-resistor array features a 147K Ohm resistance value with an exceptional 0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin SOIC ceramic package, it offers 0.1W (1/10W) power rating per resistor and a total power dissipation of 0.8W, making it suitable for high-density PCB designs. The gull-wing termination and surface-mount (SMD) configuration facilitate automated assembly, while its 100V maximum voltage rating enhances reliability in isolation circuits.
