GQ0A0247R0DT

GQ0A0247R0DT Description

The GQ0A0247R0DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation (ISOL) circuit applications. This 20-pin QSOP-packaged device integrates 10 isolated 47Ω resistors with an exceptional tolerance of ±0.5% and a low temperature coefficient of ±50ppm/°C, ensuring stable performance across a wide operating range of -70°C to +125°C. The ceramic case and gull-wing termination enable robust surface-mount assembly, while the 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability environments. Packaged in a tube, this non-automotive, non-PPAP-compliant component is ideal for prototyping and low-to-mid-volume production.

GQ0A0247R0DT Features

• Precision Thin Film Technology: Delivers ±0.5% tolerance and ±50ppm/°C TCR for minimal drift.
• Isolated Resistor Network: 10 independent 47Ω resistors in a compact 8.66mm × 6.02mm × 1.47mm QSOP package.
• High Power Handling: 1W total (0.1W per resistor) with derating up to 125°C.
• Robust Construction: Ceramic substrate and gull-wing leads for mechanical durability and solderability.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and telecom applications.
• Non-RoHS Compliant: For legacy or specialized designs requiring traditional materials.

GQ0A0247R0DT Applications

This resistor network excels in precision analog and digital circuits where isolation and stability are critical:

• Signal Conditioning: Isolated feedback paths in op-amp circuits or sensor interfaces.
• Medical Equipment: Patient-isolated measurement systems requiring low drift.
• Industrial Controls: PLCs, motor drives, and power supplies needing high-voltage isolation.
• Telecom Infrastructure: Line termination and impedance matching in base stations.
• Test & Measurement: Calibration tools and precision dividers.

Conclusion of GQ0A0247R0DT

The GQ0A0247R0DT combines precision, isolation, and power efficiency in a compact QSOP format, making it a standout choice for engineers prioritizing stability in harsh environments. Its ceramic construction and thin-film technology offer superior performance over thicker-film alternatives, while the 20-pin gull-wing design ensures reliable SMT assembly. Though not RoHS-compliant, it remains a robust solution for legacy or high-voltage designs where material restrictions are secondary to performance.
