GQ8A0268R1DT Description

The GQ8A0268R1DT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a 16-pin QSOP ceramic package, it offers a 68.1Ω resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability circuits. Its gull-wing SMD termination and 0.64mm terminal pitch facilitate compact PCB layouts, while the ceramic case enhances thermal and mechanical robustness.

GQ8A0268R1DT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±0.5%) for sensitive analog/digital systems.
• Isolated Resistor Network (ISOL): Each resistor is electrically isolated, ideal for multi-channel isolation or differential signaling.
• Ceramic QSOP Package: Superior heat dissipation and durability vs. plastic alternatives.
• Wide Temperature Range: Stable performance from -70°C to +125°C (derated power above 70°C).
• High Power Density: 0.75W total rating in a compact 4.9mm × 6.02mm × 1.47mm footprint.
• RoHS Non-Compliant: Suitable for legacy or specialized industrial systems where RoHS exemptions apply.

GQ8A0268R1DT Applications

• Medical Equipment: Patient isolation barriers, sensor interfaces.
• Industrial Automation: PLCs, isolated ADC/DAC reference circuits.
• Telecom Infrastructure: Line drivers, impedance matching in base stations.
• Test & Measurement: Precision voltage dividers, calibration networks.
• Aerospace/Military: Ruggedized avionics due to ceramic packaging and wide temp range.

Conclusion of GQ8A0268R1DT

The GQ8A0268R1DT excels in applications requiring high precision, isolation, and thermal resilience. Its ceramic QSOP construction, combined with thin film stability, makes it a superior choice over plastic-cased networks in harsh environments. While not RoHS-compliant, it remains critical for legacy systems or niche industrial uses. Engineers will value its space-saving design, low TCR, and 0.5% tolerance for error-sensitive designs.
