GS4A024991DT Description

The GS4A024991DT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 4.99KΩ resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, this thin-film ceramic-based network ensures stable performance across a wide temperature range (70°C to 125°C). Its isolated circuit design (ISOL) allows independent resistor operation, making it ideal for precision signal conditioning. The SOIC-C series construction offers robust 100V maximum voltage rating and 0.4W total power dissipation (0.1W per resistor), housed in a compact 4.9mm x 5.99mm x 1.45mm footprint with gull-wing leads for reliable PCB mounting.
