GQ8A0228R7JGT Description

The GQ8A0228R7JGT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications requiring stable resistance values and robust thermal performance. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers a 28.7Ω resistance per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable operation across a wide temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it is engineered for demanding environments. The isolated (ISOL) circuit design and gull-wing termination facilitate easy PCB integration, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.
