GQ0A0127R4GFT Description

The GQ0A0127R4GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 20-pin QSOP package integrates 10 isolated resistors, each with a 27.4Ω resistance, 2% tolerance, and a ±100ppm/°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 0.64mm terminal pitch ensure compatibility with surface-mount (SMD) assembly processes.

GQ0A0127R4GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistors (ISOL): Each of the 10 resistors is electrically isolated, enabling flexible circuit design.
• Ceramic Case Style: Enhances thermal dissipation and mechanical robustness in harsh environments.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained PCBs.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C).
• Automotive-Grade Alternatives: While not PPAP-certified, its performance suits industrial and telecom applications.
