GQ8A0139R0JDT Description

The GQ8A0139R0JDT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision isolation circuits. Housed in a 16-pin QSOP ceramic package, it offers a 39Ω resistance per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The device features gull-wing terminations for reliable surface-mount (SMD) assembly, with a compact footprint (4.9mm x 6.02mm x 1.47mm) and robust ceramic construction for enhanced thermal and mechanical durability. Rated for 0.1W per resistor and 0.75W total power dissipation, it supports 100V maximum voltage, making it suitable for demanding analog and digital circuits.

GQ8A0139R0JDT Features

• Isolation-Centric Design: Optimized for ISOL (isolation) circuit applications, ensuring minimal crosstalk.
• High Power Density: 0.75W total power rating in a compact QSOP package, outperforming standard arrays.
• Precision Thin Film: ±100ppm/°C TCR and 5% tolerance for consistent performance in temperature-variable environments.
• Robust Construction: Ceramic case provides superior heat dissipation and mechanical strength vs. plastic alternatives.
