GQ8A021473JBT Description

The GQ8A021473JBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-resistor network features a 147K Ohm resistance per element with a 5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating temperatures. Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and supports a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the isolated (ISOL) circuit designator ensures individual resistor independence. The device operates within a -70°C to +125°C temperature range, making it suitable for demanding environments.
