GQ8A0143R0GCT Description

The GQ8A0143R0GCT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a ceramic QSOP package, this 16-pin surface-mount device (SMD) offers 43Ω resistance per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient. Rated for 0.1W (1/10W) per resistor and 0.75W (3/4W) total power dissipation, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for demanding environments. The isolated (ISOL) circuit design ensures minimal crosstalk, while the gull-wing termination facilitates robust PCB mounting.
