GS4A012212FFT

GS4A012212FFT Description

The GS4A012212FFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 22.1kΩ resistance and a tight ±1% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in demanding environments. Its ±100ppm/°C temperature coefficient guarantees stable performance under thermal variations. The SOIC-C series construction offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for easy surface-mount assembly. Rated for 100V maximum voltage and 0.1W power per resistor (0.4W total), it is ideal for analog signal conditioning and precision divider networks.
