GQCA031801BBT Description

The GQCA031801BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 24-pin QSOP package features 12 isolated 1.8KΩ resistors with a 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a ceramic substrate, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The gull-wing SMD termination facilitates reliable surface mounting, while the 100V maximum voltage rating and 1W total power dissipation (0.1W per resistor) make it suitable for precision analog and digital circuits.

GQCA031801BBT Features

• High Precision: 0.1% tolerance and ±25ppm/°C TCR for consistent performance.
• Robust Construction: Ceramic case ensures thermal and mechanical resilience.
• Isolated Design: 12 independent resistors (ISOL circuit designator) for flexible circuit integration.
• Space-Efficient: Compact QSOP package (8.66mm × 6.02mm × 1.47mm) with 0.64mm pitch.
• Reliable Termination: Gull-wing leads for secure SMD assembly.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power.
• Non-Automotive: Ideal for industrial and instrumentation use (PPAP not required).

GQCA031801BBT Applications

This resistor network excels in:

• Precision voltage dividers and signal conditioning in test/measurement equipment.
• Analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) requiring matched resistances.
• Medical devices and industrial controls where stability under thermal stress is critical.
• Communication systems (e.g., RF modules) demanding low-noise, high-accuracy components.
• Power management circuits due to its 100V rating and derated power handling.
