GQ8A028661GGT Description

The GQ8A028661GGT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications requiring stable resistance values and tight tolerances. Encased in a ceramic QSOP package, this 16-pin SMD component offers an 8.66KΩ resistance per resistor with a 2% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, it is engineered for demanding environments. The gull-wing termination and 0.64mm terminal pitch facilitate easy surface mounting, while the ceramic case enhances thermal and mechanical stability.

GQ8A028661GGT Features

• Precision Thin Film Technology: Delivers low noise and high stability, ideal for sensitive analog circuits.
• Isolated Resistor Network (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Robust Ceramic Package: Provides superior heat dissipation and mechanical strength compared to plastic alternatives.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated above 70°C), suited for industrial and automotive under-hood applications (though not PPAP-certified).
• Compact QSOP-16 Footprint: 4.9mm x 6.02mm x 1.47mm dimensions with tight tolerances (±0.1mm length/height, ±0.2mm depth) enable high-density PCB layouts.

GQ8A028661GGT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers and feedback networks in op-amp circuits.
• Medical Equipment: Stable resistance for patient monitoring systems and diagnostic devices.
• Industrial Automation: PLC I/O modules and sensor interfaces requiring isolation and durability.
• Telecommunications: Line termination and impedance matching in high-frequency RF systems.
• Test & Measurement: Calibration circuits where low TCR (±50ppm/°C) minimizes drift.

Conclusion of GQ8A028661GGT

The GQ8A028661GGT stands out for its combination of precision, power handling, and rugged packaging, making it a superior choice over plastic-encased networks in harsh environments. While not RoHS-compliant or automotive-grade, its ceramic construction, isolated design, and thin-film accuracy cater to specialized industrial, medical, and telecom applications. Engineers will appreciate its balance of performance, size, and reliability in critical circuits.
