GQ8B015490DAT Description

The GQ8B015490DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 549 Ohm resistance value, offering a tight tolerance of ±0.5% and a low temperature coefficient of ±100ppm/°C. Encased in a ceramic package, it ensures excellent thermal stability and durability. The network operates within a wide temperature range of -70°C to +125°C, with a derated power range up to 125°C, making it suitable for harsh environments. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the 0.64mm terminal pitch ensures compact placement in space-constrained designs.

GQ8B015490DAT Features

• Precision Performance: 0.5% tolerance and ±100ppm/°C TCR ensure stable operation in precision circuits.
• Robust Construction: Ceramic case and thin-film technology provide superior thermal management and long-term reliability.
• High Power Handling: 0.75W (3/4W) total power rating, with 0.05W (1/20W) per resistor, ideal for distributed power applications.
• Space-Efficient: QSOP package (4.9mm x 6.02mm x 1.47mm) with 16 gull-wing terminals optimizes board space.
• Wide Voltage Range: Supports up to 100V maximum voltage, suitable for industrial and automotive-grade systems (though not PPAP/automotive certified).
• Stable Thermal Performance: Operates reliably from -70°C to +125°C, with derated power at elevated temperatures.
