GS4A021271FFT

GS4A021271FFT Description

The GS4A021271FFT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 1.27KΩ and a tight ±1% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in harsh environments. Its ±50ppm/°C temperature coefficient guarantees stable performance under thermal stress. The SOIC-C series construction offers a compact footprint (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations for easy surface-mount assembly. Rated for 100V maximum voltage and 0.4W total power dissipation, it is ideal for precision analog and digital circuits.
