GQ8A031501DAT Description

The GQ8A031501DAT 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 1.5KΩ resistance per resistor with an ultra-tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating and 100V maximum voltage rating, this surface-mount (SMD) network is engineered for reliability in precision circuits. Its gull-wing termination and ceramic case provide robust mechanical and thermal performance, while the isolated (ISOL) circuit design minimizes crosstalk.
