GQ0A016490GT

GQ0A016490GT Description

The GQ0A016490GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 10-resistor isolated network features a 649Ω resistance per element with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring reliable performance across a 70°C to 125°C operating range. Encased in a ceramic QSOP package, it offers excellent thermal stability and durability, with a 1W total power rating (0.1W per resistor). The 20-pin gull-wing SMD termination facilitates easy surface mounting, while the 100V maximum voltage rating makes it suitable for moderate-voltage circuits.

GQ0A016490GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Robust Ceramic Package: Enhances thermal dissipation and mechanical strength in harsh environments.
• Compact QSOP Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances ensure space-efficient PCB layouts.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C).
• Gull-Wing Termination: Ensures secure soldering and compatibility with automated assembly processes.

GQ0A016490GT Applications

• Industrial Control Systems: Precision voltage dividers, feedback networks, and signal conditioning.
• Test & Measurement Equipment: High-accuracy calibration circuits and sensor interfaces.
• Medical Electronics: Isolated signal paths in patient monitoring devices.
• Automotive (Non-Automotive Rated): Engine control modules (ECUs) where thermal stability is critical (note: not PPAP/automotive-qualified).
• Telecommunications: Impedance matching and line termination in RF modules.

Conclusion of GQ0A016490GT

The GQ0A016490GT excels in applications demanding precision, thermal resilience, and compact integration. Its ceramic QSOP package, isolated thin-film resistors, and wide operational range make it a superior choice over generic networks in mission-critical systems. While not RoHS-compliant or automotive-grade, its low TCR, high power handling, and robust construction position it as a reliable solution for industrial, medical, and telecom designs requiring long-term stability. Engineers should verify compatibility for high-reliability use cases due to its "Unconfirmed" part status.
