GQCB011651FBT Description

The GQCB011651FBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 23-resistor array features a 1.65KΩ resistance value per resistor with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 24-pin QSOP ceramic package, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the rectangular ceramic case ensures durability and thermal stability.

GQCB011651FBT Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±100ppm/°C) for stable operation.
• Robust Ceramic Package: Enhances thermal performance and mechanical strength in harsh environments.
• High-Density Integration: 23 resistors in a compact QSOP-24 footprint (8.66mm × 6.02mm × 1.47mm) save board space.
• Automated Assembly Friendly: Gull-wing leads and 0.64mm terminal pitch streamline SMD processes.
• Wide Operating Range: Rated for 125°C max temperature and derated power up to 125°C.
• Non-Automotive, Non-PPAP: Ideal for industrial and commercial applications where PPAP compliance isn’t required.
