GQ0A014531FAT Description

The GQ0A014531FAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a 4.53KΩ resistance and a tight 1% tolerance, ensuring consistent performance in precision circuits. The ceramic case style and gull-wing termination enable reliable surface-mount assembly, while the ±100ppm/°C temperature coefficient guarantees stability across a wide operating range of -70°C to +125°C. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for robustness in industrial and telecommunications environments.

GQ0A014531FAT Features

• High Precision: 1% tolerance and thin-film technology for low noise and drift.
• Isolated Design: Circuit designator "ISOL" ensures independent resistor performance.
• Wide Temperature Range: Derated power operation up to 125°C, suitable for harsh conditions.
• Compact & Durable: Ceramic QSOP package (8.66mm x 6.02mm x 1.47mm) with ±0.1mm dimensional tolerances.
• Surface-Mount Ready: Gull-wing terminals with 0.64mm pitch for automated PCB assembly.
• Non-Automotive: Compliant with EAR99 but not PPAP or automotive-grade.
