GS4A021213FT

GS4A021213FT Description

The GS4A021213FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 121KΩ resistance and a tight ±1% tolerance. The device operates within a wide temperature range of 70°C to 125°C (derated) and delivers a 0.1W power rating per resistor (0.4W total). Its ±50ppm/°C temperature coefficient ensures minimal resistance drift, while the 100V maximum voltage rating and gull-wing termination make it suitable for surface-mount applications. The ceramic case enhances thermal stability and durability, and the SOIC package (4.9mm x 5.99mm x 1.45mm) complies with industry-standard footprints.
