GQCA021370DCT

GQCA021370DCT Description

The GQCA021370DCT 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 137 Ω resistance value and a tight 0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and reliability, with a maximum operating temperature of 125°C and a ±50ppm/°C temperature coefficient. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits.

GQCA021370DCT Features

• High Precision: 0.5% tolerance and ±50ppm/°C TCR ensure stable performance in temperature-varying environments.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical durability.
• Isolated Design: 12 independent resistors (ISOL circuit designator) allow flexible circuit configurations.
• Surface-Mount Compatibility: Gull-wing termination and 0.64mm terminal pitch enable easy PCB integration.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• Compact Dimensions: 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D) for space-constrained designs.

GQCA021370DCT Applications

This resistor network excels in:

• Precision Voltage Dividers: Critical in ADC/DAC reference circuits due to low TCR and tolerance.
