GQCA033321BBT Description

The GQCA033321BBT 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 3.32KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Encased in a ceramic package, it offers superior thermal stability and reliability across a wide temperature range of -70°C to +125°C. With a ±25ppm/°C temperature coefficient, this network minimizes resistance drift under varying environmental conditions. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its 100V maximum voltage rating and 1W total power dissipation make it suitable for high-performance systems.

GQCA033321BBT Features

• Precision Performance: 0.1% tolerance and ±25ppm/°C TCR ensure minimal deviation in critical circuits.
• Robust Construction: Ceramic case enhances thermal management and mechanical durability.
• High-Density Integration: 12 resistors in a compact QSOP-24 package (8.66mm x 6.02mm x 1.47mm) save board space.
• Reliable Termination: Gull-wing leads with 0.64mm pitch provide secure soldering and compatibility with automated assembly.
• Wide Operating Range: Functions reliably from -70°C to +125°C, ideal for industrial and automotive environments (though not PPAP/automotive-certified).
• Isolated Design: Independent resistors (marked by ISOL circuit designator) allow flexible circuit configurations without crosstalk.
