GQCA0266R5JGT

GQCA0266R5JGT Description

The GQCA0266R5JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 24-pin QSOP package integrates 12 isolated resistors, each with a 66.5Ω resistance and a tight ±5% tolerance, ensuring consistent performance across circuits. The ceramic case and gull-wing termination enable robust surface-mount (SMD) integration, while the ±50ppm/°C temperature coefficient guarantees minimal drift over its operating range of -70°C to +125°C. With a 100V maximum voltage rating and 0.1W power dissipation per resistor, this network is engineered for demanding environments.

GQCA0266R5JGT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Design (ISOL): 12 independent resistors prevent cross-talk, ideal for multi-channel systems.
• High Power Handling: 1W total power rating (0.1W per resistor) with derating up to 125°C.
• Robust Construction: Ceramic substrate and gull-wing leads ensure mechanical durability and solderability.
• Compact QSOP Package: 8.66mm × 6.02mm footprint with 0.64mm pitch, saving PCB space.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, suited for industrial and automotive (non-PPAP) applications.
