GQ8A027870CT Description

The GQ8A027870CT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding isolation applications. Encased in a ceramic QSOP package, it offers a 787Ω resistance per element with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. Rated for 0.75W (3/4W) total power (0.1W per resistor) and 100V maximum voltage, this 16-pin gull-wing SMD device combines high reliability with compact dimensions (4.9mm x 6.02mm x 1.47mm). Its isolated (ISOL) circuit design minimizes crosstalk, making it ideal for precision analog and mixed-signal circuits.

GQ8A027870CT Features

• Thin-film technology: Delivers superior accuracy (±0.25%) and low TCR (±50ppm/°C) vs. thick-film alternatives.
• Ceramic QSOP package: Enhances thermal performance and mechanical robustness in harsh environments.
• High power density: 0.75W total dissipation in a miniature footprint, optimizing board space.
• Gull-wing termination: Ensures reliable surface-mount assembly and solder joint integrity.
• Non-automotive (PPAP No): Suitable for industrial, medical, and telecom applications where precision is critical.
• Non-RoHS compliant: Preferred for legacy or high-reliability systems exempt from RoHS restrictions.
