GQ0A034702JAT Description

The GQ0A034702JAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 20-pin QSOP package integrates 10 isolated 47kΩ resistors with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). The ceramic case style and gull-wing termination make it ideal for surface-mount (SMD) applications, while its 1W total power rating (0.1W per resistor) supports moderate power dissipation.

GQ0A034702JAT Features

• Isolated Resistor Network: 10 independent resistors (47kΩ each) with 100V maximum voltage rating, suitable for signal isolation.
• Precision Thin Film Technology: Delivers low noise and high stability, with a tight ±25ppm/°C TCR for minimal drift.
• Robust Construction: Ceramic substrate ensures durability and thermal performance, with a rectangular QSOP package (8.66mm x 6.02mm x 1.47mm).
• Surface-Mount Design: Gull-wing leads and 0.64mm terminal pitch enable easy PCB integration in space-constrained designs.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C, making it suitable for industrial and automotive environments (though not PPAP/automotive-certified).

GQ0A034702JAT Applications

• Signal Conditioning: Ideal for ADC/DAC reference networks, voltage dividers, and feedback circuits in precision analog systems.
• Industrial Electronics: Used in PLC modules, sensor interfaces, and power supply control due to its isolation and thermal resilience.
• Test & Measurement Equipment: Ensures accuracy in multichannel instrumentation where consistent resistance values are critical.
• Medical Devices: Suitable for patient monitoring systems requiring stable, low-drift components.
