GS7B033900FFT

GS7B033900FFT Description

The GS7B033900FFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and tight tolerances. This 14-pin Narrow SOIC (SOIC-C Series) device integrates 13 bussed resistors, each with a 390Ω resistance and an absolute tolerance of ±1%. Built with thin-film technology, it delivers a low temperature coefficient of ±25ppm/°C, ensuring minimal resistance drift across its operating range of -70°C to +125°C. The 0.05W (1/20) power rating per resistor and 0.7W total power rating make it suitable for low-power circuits, while its 100V maximum voltage rating enhances reliability in high-voltage environments. The gull-wing termination and surface-mount design facilitate easy PCB integration.
