GQ8A021400JGT Description

The GQ8A021400JGT from TT Electronics/IRC is a high-performance, surface-mount thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 140 Ohm resistance value with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a maximum voltage rating of 100V. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.

GQ8A021400JGT Features

• High Reliability: Ceramic case and thin-film technology ensure durability and long-term stability.
• Precision Performance: Tight tolerance (±5%) and low TCR (±50ppm/°C) for consistent operation in demanding environments.
• Isolated Design (ISOL): Each resistor is electrically isolated, reducing crosstalk and improving signal integrity.
• Robust Power Handling: 0.75W total power dissipation, derated for high-temperature operation up to 125°C.
• Compact & Lightweight: QSOP package with gull-wing leads for easy surface mounting in high-density PCBs.
• Non-Automotive: Suitable for industrial, telecom, and instrumentation applications where PPAP compliance is not required.
