GS4A034222FBT Description

The GS4A034222FBT 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 42.2KΩ resistance and a tight ±1% absolute tolerance (with ±0.1% ratio tolerance). Its ±25ppm/°C temperature coefficient ensures stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint, while the gull-wing termination facilitates reliable surface-mount assembly. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, this network balances precision and durability.
