GS4A036490FT Description

The GS4A036490FT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 649Ω and a tight ±1% tolerance. Its ±25ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of 70°C to 125°C. The SOIC package (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations offers reliable surface-mount compatibility, while the ceramic case provides excellent thermal and mechanical stability. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it is ideal for precision circuits requiring low drift and high reliability.
