GS4A0144R2FFT

GS4A0144R2FFT Description

The GS4A0144R2FFT 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 44.2Ω resistance and a tight ±1% absolute tolerance. The ±100ppm/°C temperature coefficient ensures stable performance across a wide operating range of -70°C to +125°C. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this network is engineered for reliability in demanding environments. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint, while gull-wing terminations facilitate easy surface-mount assembly.
