GQ0A035490GT

GQ0A035490GT Description

The GQ0A035490GT 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 10-resistor network features a 549 Ohm resistance per element with a tight 2% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a 20-pin QSOP ceramic package, it offers 1W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuit isolation (ISOL) applications. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical stability.

GQ0A035490GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Ceramic QSOP Package: Provides superior heat dissipation and durability in harsh environments.
• Isolated Resistor Network (ISOL): Ensures minimal crosstalk between channels, ideal for signal conditioning.
• Wide Operating Range: Rated for -55°C to +125°C (derated power up to 125°C), suitable for industrial and automotive-adjacent applications.
• Robust Construction: ±0.1mm height/length tolerances and 0.64mm terminal pitch enable consistent manufacturability.
• Non-Automotive (PPAP No): Optimized for commercial and industrial use where high reliability is critical.

GQ0A035490GT Applications

This resistor network excels in:

• Analog Signal Processing: Voltage dividers, DAC/ADC reference circuits, and sensor interfaces.
• Power Supply Isolation: Feedback networks in DC-DC converters or LDO regulators.
• Medical/Test Equipment: Precision instrumentation requiring low TCR and long-term stability.
• Telecom Infrastructure: Line termination and impedance matching in high-frequency PCBs.
• Industrial Controls: PLCs and motor drives where temperature fluctuations are common.

Conclusion of GQ0A035490GT

The GQ0A035490GT stands out for its combination of precision, power handling, and isolation capabilities in a compact QSOP format. Its ceramic construction and thin-film technology make it a superior choice over epoxy-based networks in high-temperature or precision-critical designs. While not automotive-grade, its EU RoHS non-compliance may limit use in certain regions, but it remains a robust solution for industrial, telecom, and medical electronics demanding tight tolerances and reliability.
