GQ0A036490GGT Description

The GQ0A036490GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 10-resistor array features a 649Ω resistance value per resistor with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 20-pin QSOP ceramic package, it offers excellent thermal stability and durability. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the isolated (ISOL) circuit designator ensures individual resistor independence. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is ideal for demanding electronic circuits.

GQ0A036490GGT Features

• Precision Thin Film Technology: Delivers high accuracy (±2%) and low TCR (±25ppm/°C) for stable operation.
• Robust Ceramic Package: Enhances thermal performance and mechanical strength.
• Isolated Resistor Configuration: Each of the 10 resistors operates independently, suitable for multi-channel applications.
• Surface-Mount Gull Wing Terminals: Ensures reliable solder joints and compatibility with automated assembly.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Compact QSOP-20 Footprint: Saves board space with 8.66mm × 6.02mm × 1.47mm dimensions and 0.64mm terminal pitch.
