GQ8A014990DBT Description

The GQ8A014990DBT from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, it offers a 499Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). Rated for 0.75W total power dissipation (0.1W per resistor) and 100V maximum voltage, this 16-pin gull-wing SMD device is ideal for space-constrained PCB designs. Its isolated (ISOL) circuit design minimizes crosstalk, while the ceramic substrate enhances thermal performance and reliability.

GQ8A014990DBT Features

• Precision Thin Film Technology: Delivers consistent performance with low noise and high accuracy.
