GS4A027681FFT

GS4A027681FFT Description

The GS4A027681FFT 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 resistance value of 7.68KΩ and a tight ±1% absolute tolerance. The network operates over a wide temperature range (70°C to 125°C) with a low temperature coefficient of ±50ppm/°C, ensuring stable performance under varying thermal conditions. Encased in a rectangular SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for reliable surface-mount assembly. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it is ideal for high-density PCB designs requiring precision resistance matching.
