GS4A0242R2GDT Description

The GS4A0242R2GDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a resistance value of 42.2Ω and a tight ±2% absolute tolerance. The device operates over a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in demanding environments. Its ±50ppm/°C temperature coefficient and ±0.5% ratio tolerance make it ideal for circuits requiring stable, matched resistances. The 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) further enhance its versatility.
