GQ0A0268R1GT Description

The GQ0A0268R1GT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 68.1Ω resistance, 2% tolerance, and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. The ceramic case and gull-wing termination provide robust mechanical and electrical reliability, while the 0.1W power rating per resistor (1W total) and 100V maximum voltage rating make it suitable for precision circuits. Packaged in a tube, this surface-mount device (SMD) is ideal for automated assembly processes.
