GQ8A026980DT Description

The GQ8A026980DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 8-resistor isolated network features a 698Ω resistance value with a tight 0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a ceramic QSOP package, it offers 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-density circuits. The 16-pin gull-wing SMD termination ensures reliable surface-mount assembly, while its 100V maximum voltage rating enhances durability in high-voltage environments.

GQ8A026980DT Features

• Precision Thin-Film Technology: Delivers high accuracy (±0.5%) and low TCR (±50ppm/°C) for stable performance.
• Robust Ceramic Package: Provides excellent thermal stability and mechanical strength.
• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in sensitive applications.
• Compact QSOP Form Factor: 4.9mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm length/height, ±0.2mm depth) enable high-density PCB layouts.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) supports power-sensitive designs.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.

GQ8A026980DT Applications

• Industrial Electronics: Precision voltage dividers, feedback networks, and sensor conditioning circuits.
• Telecommunications: Signal processing and impedance matching in RF modules.
• Medical Devices: High-reliability analog circuits where stability is critical.
• Automotive (Non-Automotive Compliant): Test and measurement equipment (note: not PPAP or automotive-qualified).
• Power Management: Current sensing and load balancing in DC-DC converters.

Conclusion of GQ8A026980DT

The GQ8A026980DT excels in applications requiring precision, thermal stability, and compactness. Its ceramic construction, isolated design, and thin-film technology make it superior to standard thick-film networks, particularly in environments with high thermal stress or stringent accuracy requirements. While not RoHS-compliant or automotive-grade, it remains a top choice for industrial, medical, and telecom systems where performance outweighs regulatory constraints. Ideal for engineers prioritizing reliability, miniaturization, and electrical precision.
