GS4A033300FFT

GS4A033300FFT Description

The GS4A033300FFT 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 330Ω resistance and a tight ±1% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures stability across a wide operating range (70°C to 125°C derated, 125°C max). 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. The 0.1W power rating per resistor (0.4W total) and 100V max voltage rating make it suitable for demanding circuits requiring isolation and precision.
