GQCB014991JFT Description

The GQCB014991JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 24-pin QSOP package integrates 23 resistors, each with a 4.99KΩ resistance value and a 5% tolerance, ensuring reliable signal conditioning and voltage division. The network operates within a wide temperature range of 70°C to 125°C (derated) and features a ±100ppm/°C temperature coefficient, making it suitable for environments with thermal fluctuations. Encased in a ceramic substrate, it offers excellent thermal stability and durability, with a 1W total power rating (0.05W per resistor). Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating ensures robustness in high-voltage applications.
