GQCB014121FFT Description

The GQCB014121FFT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter Small Outline Package) device integrates 23 resistors with a 4.12KΩ resistance value, offering a tight 1% tolerance and a low ±100ppm/°C temperature coefficient. Encased in a ceramic housing, it ensures superior thermal stability and durability. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of 70°C to 125°C. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.
