GS4A012800FFT

GS4A012800FFT Description

The GS4A012800FFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 4-resistor network features isolated elements (ISOL) in an 8-pin narrow SOIC package, ensuring minimal crosstalk and optimal signal integrity. With a 280Ω resistance value, ±1% absolute tolerance, and ±100ppm/°C temperature coefficient, it delivers consistent performance across a wide temperature range (70°C to 125°C). The thin-film technology ensures low noise and high accuracy, while the 100V maximum voltage rating and 0.1W power rating per resistor make it suitable for demanding circuits.
