GS4A0249R9GT

GS4A0249R9GT Description

The GS4A0249R9GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 49.9Ω and a tight ±2% tolerance. The SOIC-C series construction ensures excellent thermal stability, with a low ±50ppm/°C temperature coefficient, making it ideal for circuits requiring consistent performance across a wide temperature range (70°C to 125°C). With a maximum operating voltage of 100V and a power rating of 0.1W per resistor (0.4W total), this network is engineered for reliability in surface-mount applications.
