GQCA031780GFT Description

The GQCA031780GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 178Ω resistance value and a tight 2% tolerance. Encased in a ceramic package, it offers excellent thermal stability with a low ±25ppm/°C temperature coefficient, ensuring minimal resistance drift across its -70°C to +125°C operating range. Rated for 100V maximum voltage and 0.1W power dissipation per resistor (1W total), it is ideal for surface-mount (SMD) designs requiring compact, reliable passive components.

GQCA031780GFT Features

• Precision Thin Film Technology: Delivers superior accuracy (±2%) and low TCR (±25ppm/°C) for stable performance in temperature-sensitive circuits.
• Isolated Resistor Network (ISOL): 12 independent resistors in a single package, reducing board space and simplifying layout.
• Robust Ceramic QSOP Case: Enhances thermal dissipation and mechanical durability in harsh environments.
• Gull Wing Termination: Ensures reliable solder joints for automated PCB assembly processes.
• Wide Operating Range: Functions reliably from -70°C to +125°C, making it suitable for industrial and automotive-grade applications (though not PPAP/automotive certified).
• Compact Dimensions: 8.66mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm) for high-density designs.
