GQCA021910JFT

GQCA021910JFT Description

The GQCA021910JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 24-pin QSOP package features 12 isolated resistors, each with a 191Ω resistance value and a 5% tolerance, ensuring reliable performance in demanding circuits. The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the ±50ppm/°C temperature coefficient guarantees minimal resistance drift across its operating range of -70°C to +125°C. With a 0.1W power rating per resistor (1W total) and a 100V maximum voltage rating, this network is ideal for analog signal conditioning, isolation, and voltage division in industrial and telecom systems.
