GQ8A017682DBT Description

The GQ8A017682DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter-Small Outline Package) device features 8 isolated resistors, each with a 76.8KΩ resistance and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The gull-wing termination enables reliable surface-mount (SMD) assembly, while the 0.64mm terminal pitch accommodates high-density PCB layouts. With a 0.75W total power rating (0.1W per resistor) and a ±100ppm/°C temperature coefficient, this network delivers consistent performance across a wide 70°C to 125°C derated power range.

GQ8A017682DBT Features

• Precision Thin Film Technology: Ensures low noise and high stability for sensitive analog circuits.
• Isolated Resistor Design (ISOL): Each of the 8 resistors operates independently, ideal for multi-channel applications.
• Robust Ceramic Case: Provides excellent thermal conductivity and mechanical strength.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) at 125°C, derated for extended reliability.
• Tight Tolerance & Low TCR: ±0.5% resistance accuracy and ±100ppm/°C coefficient minimize drift in varying environments.
• Compact QSOP Package: 4.9mm x 6.02mm footprint with 1.47mm profile, suited for space-constrained designs.
• 100V Maximum Voltage Rating: Suitable for industrial and instrumentation use.

GQ8A017682DBT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and DAC/ADC interfaces.
• Industrial Control Systems: Signal isolation and conditioning in PLCs and sensors.
• Medical Electronics: High-reliability instrumentation requiring stable resistance values.
