GQ8A031403JGT Description

The GQ8A031403JGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and tight tolerances. This 8-resistor isolated network features a 140K Ohm resistance per element with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). Housed in a 16-pin QSOP ceramic package, it offers superior thermal stability and durability, making it ideal for demanding environments. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this surface-mount device (SMD) is engineered for efficiency and longevity in compact circuit designs.

GQ8A031403JGT Features

• Precision Thin Film Technology: Delivers ±25ppm/°C thermal stability for minimal drift.
• High Power Handling: 0.1W per resistor (0.75W total) enables robust performance in power-sensitive applications.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Ceramic QSOP Package: Enhances thermal dissipation and mechanical strength vs. plastic alternatives.
• Gull Wing Termination: Ensures secure surface-mount (SMD) attachment with a 0.64mm pitch for high-density PCBs.
• Wide Operating Range: Functions reliably from -55°C to +125°C, suitable for industrial and automotive (non-AECQ) use.
• Non-RoHS Compliant: Preferred for legacy or specialized systems requiring leaded components.

GQ8A031403JGT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers, feedback networks in op-amp circuits.
• Medical Instrumentation: Patient monitoring devices where stability and accuracy are critical.
• Industrial Control Systems: PLCs, sensor interfaces, and power management modules.
• Telecommunications: RF and baseband circuitry requiring low-noise, stable resistance.
• Test & Measurement Equipment: Calibration tools and data acquisition systems.
