GQ8A0230R9DT Description

The GQ8A0230R9DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 30.9Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). Housed in a ceramic QSOP-16 package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing termination and 0.64mm pitch enable seamless surface-mount (SMD) integration in space-constrained designs.

GQ8A0230R9DT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±0.5%) for sensitive analog/digital systems.
• Isolated Circuit Design (ISOL): Each resistor is electrically isolated, ideal for multi-channel isolation or differential signaling.
• Robust Ceramic Package: Enhances thermal performance and mechanical durability vs. polymer-based arrays.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C).
• Compact QSOP-16 Footprint: 4.9mm x 6.02mm x 1.47mm dimensions with tight tolerances (±0.1mm length/height).
• High Power Density: 0.75W total rating outperforms similar-sized networks in power handling.
