GQ8A017500DBT Description

The GQ8A017500DBT 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, this 750Ω ±0.5% network offers 0.75W (3/4W) total power dissipation and operates across a wide temperature range of -70°C to +125°C. Its isolated (ISOL) circuit design ensures minimal crosstalk, while the ±100ppm/°C temperature coefficient guarantees stability in fluctuating thermal environments. The 16-pin gull-wing SMD termination facilitates reliable surface mounting, and the ceramic substrate enhances thermal performance and durability.
