GQ0A0229R4FT Description

The GQ0A0229R4FT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and tight tolerances. This 20-pin QSOP package integrates 10 isolated resistors, each with a 29.4Ω resistance, 1% tolerance, and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical stability and ease of surface-mount assembly, while the 100V maximum voltage rating and 1W total power dissipation make it suitable for demanding circuits.

GQ0A0229R4FT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): 10 independent resistors minimize crosstalk in multi-channel systems.
• High Power Handling: 0.1W per resistor (1W total) with derating up to 125°C.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm footprint optimizes board space in dense layouts.
• Wide Operating Range: Reliable performance from -55°C to +125°C (with power derating above 70°C).
• Automated Assembly Compatibility: 0.64mm terminal pitch and gull-wing leads suit high-volume SMD processes.
