GQ8A023090BT Description

The GQ8A023090BT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it offers a 309Ω resistance per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The device features gull-wing SMD terminations for reliable surface mounting and delivers a 0.1W power rating per resistor (0.75W total), with a 100V maximum voltage rating. Its isolated (ISOL) circuit design and ceramic case provide superior thermal and electrical performance in harsh environments.

GQ8A023090BT Features

• Precision Thin Film Technology: Delivers ±0.1% tolerance and ±50ppm/°C TCR for critical analog circuits.
