GQCB024221JCT Description

The GQCB024221JCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP device integrates 23 resistors, each with a 4.22KΩ resistance (5% tolerance) and a ±50ppm/°C temperature coefficient, ensuring stable performance across a -70°C to +125°C operating range. Encased in a ceramic package, it offers excellent thermal stability and durability, with a 1W total power rating (0.05W per resistor). The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (8.66mm × 6.02mm × 1.47mm) make it ideal for space-constrained designs.

GQCB024221JCT Features

• High-Density Integration: 23 resistors in a single 24-pin QSOP package, reducing board space and assembly complexity.
