GQ8A014320BT Description

The GQ8A014320BT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers a 432Ω resistance per element with an ultra-tight ±0.1% tolerance and a low ±100ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power (0.1W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C and withstands voltages up to 100V. Its isolated (ISOL) circuit design ensures minimal crosstalk, making it ideal for precision analog and digital systems.

GQ8A014320BT Features

• High Precision: 0.1% tolerance and thin film technology ensure stable, repeatable performance in critical circuits.
• Robust Construction: Ceramic case enhances thermal stability and durability, even in harsh environments.
• Space-Efficient: Compact QSOP package (4.9mm x 6.02mm x 1.47mm) with gull-wing leads for high-density PCB layouts.
• Isolated Design: Independent resistors (ISOL) reduce interference, suited for multi-channel systems.
• Derated Power Handling: Maintains performance up to 125°C with derated power capabilities.
• Non-Automotive: Compliant with EAR99 (ECCN) but not PPAP or automotive-grade.

GQ8A014320BT Applications

• Industrial Electronics: Precision voltage dividers, feedback networks, and sensor conditioning in PLCs and instrumentation.
