GQ8B014990FBT Description

The GQ8B014990FBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 499Ω resistance value, each offering a tight 1% tolerance and a low ±100ppm/°C temperature coefficient. Encased in a ceramic substrate, it delivers superior thermal stability and reliability across an extended operating temperature range of 70°C to 125°C. With a total power rating of 0.75W (3/4W) and 0.05W (1/20W) per resistor, it balances compactness with robust performance. The gull-wing termination ensures secure PCB mounting, while the 100V maximum voltage rating makes it suitable for high-voltage circuits.

GQ8B014990FBT Features

• High-Density Integration: 15 resistors in a compact 4.9mm × 6.02mm × 1.47mm QSOP package, ideal for space-constrained designs.
• Precision Performance: 1% tolerance and ±100ppm/°C TCR ensure consistent signal integrity in precision analog circuits.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical durability.
• Automated Assembly Friendly: Gull-wing leads with 0.64mm pitch simplify pick-and-place processes.
• Wide Voltage Compatibility: 100V rating supports industrial and telecom applications.
• Non-Automotive Grade: Suitable for commercial and industrial use (PPAP not required).
