GQ0A0145R3GT

GQ0A0145R3GT Description

The GQ0A0145R3GT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP surface-mount device integrates 10 isolated resistors, each with a 45.3 Ω resistance, 2% tolerance, and a ±100 ppm/°C temperature coefficient. Encased in a robust ceramic package, it offers superior thermal stability and reliability across a wide temperature range (70°C to 125°C). With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for precision and durability in compact designs.

GQ0A0145R3GT Features

• Isolated Circuit Design (ISOL): Ensures minimal crosstalk between resistors, ideal for high-impedance or noise-sensitive circuits.
• Ceramic QSOP Package: Provides excellent thermal dissipation and mechanical strength, outperforming standard plastic packages.
• Thin-Film Technology: Delivers low noise, high stability, and tight tolerance (±2%) for precision applications.
• Gull Wing Termination: Facilitates reliable surface-mount assembly with a 0.64mm terminal pitch for high-density PCB layouts.
• Extended Temperature Range: Operates reliably up to 125°C, making it suitable for industrial and automotive-adjacent environments (though not PPAP/Automotive certified).
• Non-RoHS Compliance: May be preferred for legacy or specialized applications requiring traditional materials.

GQ0A0145R3GT Applications

• Signal Isolation & Conditioning: Perfect for analog/digital interfaces, sensor networks, and feedback loops where isolation reduces interference.
• Medical & Test Equipment: High stability and low drift are critical for precision measurement devices.
• Industrial Control Systems: Ceramic construction withstands harsh environments, such as motor drives or power supplies.
• Telecommunications: Thin-film resistors ensure signal integrity in RF and baseband circuitry.
• Legacy Electronics Repair: Non-RoHS compliance suits maintenance of older systems.
