GS4A028200FAT

GS4A028200FAT Description

The GS4A028200FAT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 820Ω and a tight ±1% absolute tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing termination offers robust surface-mount compatibility, while the ceramic case enhances thermal and mechanical durability. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it is ideal for demanding circuits requiring isolation and precision.
