GQCA024750GFT

GQCA024750GFT Description

The GQCA024750GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP package features 12 isolated resistors, each with a 475Ω resistance, 2% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic substrate, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and surface-mount design ensure reliable PCB integration, while the QSOP package (8.66mm x 6.02mm x 1.47mm) optimizes space efficiency.

GQCA024750GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): 12 independent resistors minimize crosstalk in multi-channel systems.
• Ceramic Case: Enhances thermal dissipation and mechanical robustness compared to polymer-based arrays.
• Wide Temperature Range: Operates reliably from -55°C to 125°C (derated above 70°C).
• Space-Saving QSOP Package: Ideal for high-density layouts with a 0.64mm terminal pitch.
• Non-Automotive (PPAP No): Optimized for industrial, telecom, and instrumentation use.
