GQCB014221FBT Description

The GQCB014221FBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP package features 23 resistors with a 4.22KΩ resistance value, 1% tolerance, and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case style and gull-wing termination provide robust mechanical and electrical reliability in surface-mount (SMD) applications. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is ideal for demanding circuits requiring high-density, low-power dissipation. Packaged in a tube, it suits automated assembly processes.
