GQCA021691BBT Description

The GQCA021691BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerance and stable performance. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a resistance value of 1.69KΩ and an exceptional 0.1% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a temperature coefficient of ±50ppm/°C and a power rating of 0.1W per resistor (1W total). The gull-wing termination ensures reliable surface-mount assembly, while the 100V maximum voltage rating and 125°C maximum operating temperature make it suitable for high-reliability environments.

GQCA021691BBT Features

• Precision Performance: Ultra-tight 0.1% tolerance and ±50ppm/°C TCR ensure minimal drift in critical circuits.
• Robust Construction: Ceramic case provides excellent thermal dissipation and mechanical strength.
• High-Density Design: 24-pin QSOP package with 0.64mm terminal pitch optimizes PCB space.
• Isolated Resistors: 12 independent resistors (ISOL configuration) prevent crosstalk in sensitive applications.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial and automotive-grade systems (though not PPAP/automotive certified).
• Surface-Mount Ready: Gull-wing leads facilitate automated assembly processes.
