GQ8A034300JFT Description

The GQ8A034300JFT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance values and low thermal drift. Housed in a 16-pin QSOP ceramic package, it features 430Ω resistors with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a -70°C to +125°C operating range. The isolated (ISOL) circuit design allows independent resistor operation, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for moderate power dissipation. Its gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration.

GQ8A034300JFT Features

• Precision Thin Film Technology: Delivers stable resistance with low noise and high accuracy (±25ppm/°C).
• Robust Ceramic Case: Enhances thermal stability and mechanical durability in harsh environments.
• Isolated Resistor Network (ISOL): Each resistor operates independently, ideal for multi-channel designs.
• Wide Operating Range: Functions reliably from -70°C to +125°C, derated at higher temperatures.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length).
• High Voltage Rating: Supports up to 100V, suitable for industrial and automotive-grade circuits (non-PPAP).
