GS4A036491GFT Description

The GS4A036491GFT from TT Electronics/IRC is a high-precision 4-resistor isolated network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC ceramic package, it features thin-film technology for superior stability and accuracy. With a resistance value of 6.49KΩ (±2% tolerance) and a ±25ppm/°C temperature coefficient, this network ensures reliable performance across a wide temperature range (70°C to 125°C). The isolated circuit design (ISOL) allows independent resistor operation, making it ideal for precision voltage division and signal conditioning. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it meets stringent requirements for industrial and instrumentation systems.
