GQCA033322DBT Description

The GQCA033322DBT 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 33.2KΩ resistance value and an ultra-tight ±0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and reliability, with a ±25ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures secure surface-mount (SMD) attachment, while the 1W total power rating (0.1W per resistor) makes it suitable for power-sensitive designs.

GQCA033322DBT Features

• Precision Performance: 0.5% tolerance and ±25ppm/°C TCR ensure minimal drift in high-accuracy circuits.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical durability.
• High Voltage Handling: Supports up to 100V maximum voltage rating, ideal for industrial and instrumentation use.
• Space-Efficient: Compact QSOP package (8.66mm × 6.02mm × 1.47mm) with 0.64mm terminal pitch for dense PCB layouts.
• Isolated Design: 12 independent resistors (ISOL circuit designator) prevent cross-talk in multi-channel systems.
• Non-Automotive: Suitable for commercial and industrial applications where PPAP compliance is not required.

GQCA033322DBT Applications

This resistor network excels in precision analog and mixed-signal circuits, including:

• Medical Equipment: Patient monitoring systems requiring stable signal conditioning.
