GQCA036490JGT Description

The GQCA036490JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 24-pin QSOP package features 12 isolated resistors, each with a 649Ω resistance value and a tight ±5% tolerance, ensuring consistent performance in demanding circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift across its operating range of 70°C to 125°C. With a maximum voltage rating of 100V and a 1W total power dissipation (0.1W per resistor), this network is ideal for analog signal processing, isolation, and voltage division tasks.
