GS4A036490GBT Description

The GS4A036490GBT 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 649Ω resistance and a tight ±2% absolute tolerance. Its ±25ppm/°C temperature coefficient ensures stability across a wide operating temperature range of -70°C to +125°C, making it suitable for demanding environments. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations offers reliable surface-mount compatibility, while the 0.1W power rating per resistor (0.4W total) balances performance and thermal management.
