GQ8B011781CBT Description

The GQ8B011781CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerance and stability. This 15-resistor BUS-configuration array offers a 1.78KΩ resistance value with an exceptional ±0.25% tolerance and a ±100ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it features gull-wing terminations for robust surface-mount (SMD) assembly. With a 0.75W (3/4W) total power rating (0.05W per resistor) and a 100V maximum voltage rating, this component is engineered for precision analog and digital circuits.

GQ8B011781CBT Features

• High Precision: ±0.25% tolerance and ±100ppm/°C TCR for stable performance in critical circuits.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal stability and durability.
• Space-Efficient Design: Compact QSOP package (4.9mm × 6.02mm × 1.47mm) with 0.64mm terminal pitch optimizes PCB real estate.
• Wide Operating Range: Rated for -55°C to +125°C, suitable for industrial and automotive environments (though not PPAP/AEC-Q200 qualified).
• Low Power Dissipation: 0.05W per resistor (0.75W total) balances performance with thermal management.
• Non-RoHS Compliant: Ideal for legacy or specialized applications requiring leaded components.
