GS8B031801JFT Description

The GS8B031801JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in a 16-pin narrow SOIC package, it features 15 bussed resistors with a 1.8KΩ resistance value and a ±5% absolute tolerance. The device leverages thin-film technology for stable performance, offering a low temperature coefficient of ±25ppm/°C and a power rating of 0.8W (0.05W per resistor). Its SOIC-C series construction ensures durability, with a rectangular ceramic case and gull-wing termination for reliable surface-mount assembly. Rated for 100V maximum voltage and operating within 70°C to 125°C, it is ideal for environments demanding tight resistance matching and thermal stability.
