GQ0A033921GFT Description

The GQ0A033921GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package features 10 isolated resistors, each with a 3.92KΩ resistance and a tight 2% tolerance, ensuring consistent performance in demanding circuits. The device operates over a wide temperature range of 70°C to 125°C with a ±25ppm/°C temperature coefficient, making it suitable for environments with thermal fluctuations. Its ceramic case and gull-wing termination provide robust mechanical stability and reliable surface-mount compatibility. With a maximum voltage rating of 100V and a total power dissipation of 1W (0.1W per resistor), this network balances power handling and precision.
