GQ0A031800FT

GQ0A031800FT Description

The GQ0A031800FT 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 an isolated (ISOL) circuit design, with each resistor offering 180Ω resistance at 1% tolerance and a ±25ppm/°C temperature coefficient. Encased in a ceramic QSOP package, it delivers 1W total power dissipation (0.1W per resistor) and operates reliably across a wide temperature range of 70°C to 125°C. The 20-pin gull-wing SMD termination ensures secure surface mounting, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) make it ideal for space-constrained PCB designs.

GQ0A031800FT Features

• Precision Thin Film Technology: Ensures low noise, high stability, and tight tolerance (±1%) for critical analog/digital circuits.
• Isolated Resistor Network (ISOL): Each of the 10 resistors is electrically isolated, enabling flexible circuit configurations.
• Robust Ceramic QSOP Package: Provides excellent thermal management and mechanical durability in harsh environments.
• Wide Operating Range: Rated for 100V maximum voltage and 125°C maximum temperature, suitable for industrial and automotive-adjacent applications (non-automotive PPAP).
• Gull-Wing SMD Termination: Facilitates automated assembly with a 0.64mm terminal pitch and complies with standard reflow processes.
• Non-RoHS Compliance: Suitable for legacy or specialized applications where RoHS exemptions apply.

GQ0A031800FT Applications

This resistor network excels in:

• Signal Conditioning Circuits: Precision voltage dividers, feedback networks, and sensor interfaces in test/measurement equipment.
• Industrial Control Systems: Isolated signal paths in PLCs, motor drives, and power supplies requiring stable resistance under thermal stress.
• Medical Electronics: Low-drift amplification and filtering stages in diagnostic devices (though non-automotive/non-PPAP).
• Telecom Infrastructure: Line termination and impedance matching in high-frequency communication modules.
