GS4A033900JFT Description

The GS4A033900JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features a 390Ω resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±1%. Its thin-film technology ensures low noise and high reliability, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift across the operating range of -55°C to +125°C. The SOIC-C series construction offers robust ceramic case styling, making it suitable for harsh environments. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, this component is ideal for compact, high-density PCB designs.
