GQ0A011401GT Description

The GQ0A011401GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 20-pin QSOP package features 10 isolated resistors, each with a 1.4KΩ resistance, 2% tolerance, and a ±100ppm/°C temperature coefficient, ensuring consistent performance across a wide temperature range (70°C to 125°C). The ceramic case style and gull-wing termination provide robust mechanical stability and ease of surface-mount (SMD) assembly, while the 1W total power rating (0.1W per resistor) makes it suitable for power-sensitive designs.

GQ0A011401GT Features

• High Precision: Thin-film technology delivers low noise and tight tolerance (2%), ideal for signal conditioning and analog circuits.
• Isolated Design: 10 independent resistors with 100V maximum voltage rating, reducing crosstalk in multi-channel systems.
• Thermal Stability: ±100ppm/°C TCR ensures minimal drift under thermal stress, critical for industrial and automotive environments (though not PPAP/AEC-Q200 qualified).
• Robust Construction: Ceramic substrate enhances durability and heat dissipation, while the QSOP package (8.66mm x 6.02mm x 1.47mm) offers compactness for dense PCB layouts.
• Manufacturing Efficiency: Gull-wing leads and 0.64mm terminal pitch simplify automated placement, reducing assembly costs.

GQ0A011401GT Applications

• Industrial Controls: Precision voltage dividers, feedback networks in PLCs, and sensor interfaces.
• Test & Measurement Equipment: Calibration circuits and signal attenuation where stability is paramount.
• Medical Electronics: Isolated signal paths in diagnostic devices, ensuring patient safety.
• Telecom Infrastructure: Line termination and impedance matching in high-frequency modules.
