GQ8B012872FT Description

The GQ8B012872FT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding circuit applications. This 16-pin QSOP (Quarter-Small Outline Package) device integrates 15 resistors with a 28.7KΩ resistance value, offering 1% tolerance and a ±100ppm/°C temperature coefficient for stable performance across a -70°C to +125°C range. Encased in a ceramic package, it delivers 0.75W (3/4W) total power dissipation (0.05W per resistor), making it suitable for compact, high-density PCB designs. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while its 100V maximum voltage rating supports robust operation in industrial and instrumentation systems.

GQ8B012872FT Features

• Precision Thin Film Technology: Ensures low noise and high stability for sensitive analog/digital circuits.
• Ceramic Case: Enhances thermal management and mechanical durability in harsh environments.
• BUS Circuit Designator: Optimized for bus termination, voltage division, and pull-up/down applications.
• Compact QSOP Package: 4.9mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances for space-constrained layouts.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power at elevated temperatures.
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and test equipment where precision is critical.
