GQ8B014990JDT Description

The GQ8B014990JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 499Ω resistance value and a 5% tolerance, delivering consistent performance across a wide temperature range of 70°C to 125°C. Encased in a ceramic package, it offers superior thermal stability and durability, making it ideal for surface-mount applications where space and reliability are critical. With a 0.75W (3/4W) total power rating and ±100ppm/°C temperature coefficient, this network ensures low drift and high accuracy in signal conditioning, voltage division, and bus termination circuits.

GQ8B014990JDT Features

• Thin-Film Technology: Provides excellent stability, low noise, and precise resistance matching.
• Ceramic Case Style: Enhances thermal dissipation and mechanical robustness.
• Gull Wing Termination: Facilitates reliable surface-mount assembly with a 0.64mm terminal pitch.
• High Voltage Rating: Supports up to 100V, suitable for industrial and automotive environments (though not PPAP or Automotive certified).
• Compact Dimensions: 4.9mm (L) x 6.02mm (D) x 1.47mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Non-RoHS Compliant: May be preferred for legacy or high-reliability systems requiring specific material properties.
