GS4A034222JFT Description

The GS4A034222JFT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 42.2 kΩ and a ±5% absolute tolerance. The network operates within a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring stability in harsh environments. Its ±25 ppm/°C temperature coefficient and ±1% ratio tolerance make it ideal for precision circuits requiring minimal drift. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations ensures reliable surface-mount assembly, while the 100V maximum voltage rating and 0.4W total power dissipation (0.1W per resistor) enhance durability.
