GS4A021801GFT

GS4A021801GFT Description

The GS4A021801GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 1.8KΩ resistance and a tight ±2% absolute tolerance (±1% ratio tolerance). The SOIC-C series construction ensures excellent thermal stability with a ±50ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. With a power rating of 0.1W per resistor (0.4W total) and a maximum operating temperature of 125°C, this component is engineered for reliability in demanding circuits. Its 100V maximum voltage rating and gull-wing termination facilitate easy surface-mount assembly, while the ceramic case enhances durability and heat dissipation.
