GQCA021271DBT Description

The GQCA021271DBT 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 features 12 isolated resistors, each with a 1.27 kΩ resistance, a tight ±0.5% tolerance, and a low ±50 ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) connectivity, while the 0.64 mm terminal pitch accommodates high-density PCB designs. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision and reliability in critical circuits.

GQCA021271DBT Features

• High Precision: ±0.5% tolerance and ±50 ppm/°C TCR ensure minimal drift in sensitive applications.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal and mechanical stability.
• Isolated Design: 12 independent resistors (ISOL circuit) prevent cross-talk, ideal for signal isolation.
• Space-Efficient: Compact QSOP package (8.66 x 6.02 x 1.47 mm) with 0.64 mm pitch suits miniaturized designs.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, suitable for harsh environments.
• Surface-Mount Ready: Gull-wing terminals simplify automated assembly processes.
