GQ8A0143R2JGT Description

The GQ8A0143R2JGT 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 43.2Ω 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 assembly and delivers a total power rating of 0.75W (3/4W), with 0.1W (1/10W) per resistor. Its 100V maximum voltage rating and isolated (ISOL) circuit design make it suitable for demanding applications requiring electrical separation and minimal crosstalk.

GQ8A0143R2JGT Features

• Thin Film Technology: Provides superior stability, low noise, and tight tolerance compared to thick-film alternatives.
• Ceramic Case: Enhances thermal management and durability in harsh environments.
• High Power Density: 0.75W total dissipation in a compact 4.9mm × 6.02mm × 1.47mm footprint.
• Precision Gull Wing Terminations: Ensures robust solder joints and compatibility with automated PCB assembly.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C.
• Isolated Design (ISOL): Eliminates mutual interference between resistors, ideal for signal conditioning and voltage division.
