GQ0A0268R0FDT Description

The GQ0A0268R0FDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP packaged device integrates 10 isolated 68Ω resistors with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. With a 0.1W power rating per resistor (1W total) and a 100V maximum voltage rating, it excels in demanding circuits requiring accuracy and reliability. The ceramic case and gull-wing SMD termination provide robust mechanical and thermal stability, making it suitable for automated assembly processes.

GQ0A0268R0FDT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Design (ISOL): Each of the 10 resistors is electrically independent, ideal for multi-channel isolation.
• High Power Handling: 1W total dissipation (0.1W per resistor) at 125°C derated power.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm footprint saves PCB space while supporting high-density layouts.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, outperforming standard commercial-grade networks.
• Gull-Wing Termination: Ensures secure surface mounting with a 0.64mm pitch for compatibility with fine-pitch PCBs.

GQ0A0268R0FDT Applications

• Industrial Control Systems: Precision voltage dividers, feedback networks, and signal conditioning in harsh environments.
• Test & Measurement Equipment: Calibration circuits and reference networks requiring long-term stability.
• Medical Electronics: Isolated signal paths in patient monitoring devices.
• Automotive (Non-Automotive Rated): Sensor interfaces and ECU peripheral circuits (note: not PPAP/automotive certified).
• Telecom Infrastructure: Line termination and impedance matching in high-frequency modules.

Conclusion of GQ0A0268R0FDT

The GQ0A0268R0FDT stands out for its precision, isolation, and power density in a compact QSOP format. While not RoHS-compliant or automotive-qualified, its ceramic construction, thin-film accuracy, and wide temperature range make it a top choice for industrial, medical, and telecom applications where reliability is critical. Engineers will appreciate its balance of performance and space efficiency, particularly in multi-channel systems requiring isolated resistor networks.
