GQ8A0228R7GGT Description

The GQ8A0228R7GGT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, it offers a 28.7Ω resistance per resistor with a tight 2% 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 provides independent resistors, making it ideal for applications requiring individual signal paths. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network balances power handling and precision. Its 16-pin gull-wing SMD termination ensures reliable surface-mount assembly, while the ceramic substrate enhances thermal performance and durability.
