GQ8A034702FBT Description

The GQ8A034702FBT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it offers 47KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The 16-pin gull-wing SMD configuration and 0.64mm terminal pitch facilitate compact PCB layouts, while its 0.75W (3/4W) total power rating (0.1W per resistor) supports robust operation in demanding circuits. The isolated (ISOL) circuit design enhances signal integrity, making it ideal for noise-sensitive environments.

GQ8A034702FBT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±1%) for critical analog/digital circuits.
• Ceramic QSOP Package: Combines thermal resilience (125°C max) with a compact footprint (4.9mm × 6.02mm × 1.47mm).
• High Voltage Rating: Supports up to 100V, suitable for industrial and automotive-grade designs (though not PPAP/automotive-certified).
• Isolated Resistor Network: Minimizes crosstalk in multi-channel systems like ADCs/DACs.
• Gull Wing Termination: Ensures reliable surface-mount assembly with ±0.1mm height/length tolerances.
• Non-RoHS Compliant: Note for legacy or specialized applications requiring leaded components.

GQ8A034702FBT Applications

This resistor array excels in:

• Signal Conditioning: Precision voltage dividers in sensor interfaces (e.g., thermocouples, strain gauges).
• Medical Electronics: Isolation barriers in patient monitoring equipment.
• Test & Measurement: Calibration circuits for oscilloscopes or multimeters.
• Industrial Controls: PLCs and motor drives where temperature stability is critical.
• Legacy Systems: Maintenance of non-RoHS-compliant hardware.

Conclusion of GQ8A034702FBT

The GQ8A034702FBT stands out for its combination of precision, power handling, and isolation in a space-saving QSOP format. While not suited for automotive use, its ceramic construction and thin-film technology make it a reliable choice for high-temperature, high-accuracy applications. Engineers will appreciate its repeatable performance in signal chain and isolation circuits, though RoHS compliance should be verified for modern designs.
