GQ8A0248R7DT Description

The GQ8A0248R7DT 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 48.7Ω resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The isolated (ISOL) circuit design eliminates crosstalk, making it ideal for precision analog and digital systems. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this network balances performance and reliability in compact, surface-mount designs.
