GQCB0266R5GGT Description

The GQCB0266R5GGT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 23-resistor array features a 66.5Ω resistance value per element with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Housed in a 24-pin QSOP ceramic package, it offers 1W total power dissipation (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal and mechanical durability.

GQCB0266R5GGT Features

• Precision Thin Film Technology: Delivers superior accuracy (±2%) and low TCR (±50ppm/°C) for stable signal conditioning.
• Robust Ceramic Package: Withstands high temperatures (up to 125°C) and mechanical stress, ideal for harsh environments.
• High-Density Integration: 23 resistors in a compact 8.66mm × 6.02mm × 1.47mm QSOP footprint save PCB space.
• Automation-Friendly: Gull-wing leads and 0.64mm pitch enable efficient SMT placement.
• Derated Power Handling: Maintains performance at elevated temperatures (derated up to 125°C).
• Non-Automotive Grade: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance isn’t required.
