GS4A021430FT Description

The GS4A021430FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 4-resistor isolated network features a 143Ω resistance value with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Housed in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact 4.9mm × 5.99mm footprint with a 1.63mm seated height, making it ideal for space-constrained designs. The thin-film technology provides excellent accuracy and reliability, while the gull-wing termination ensures secure surface mounting. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this component is suited for demanding electronic circuits.
