GQ8A021871JBT Description

The GQ8A021871JBT 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 1.87KΩ resistance per element with a 5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability. The isolated (ISOL) circuit design allows independent resistor operation, making it ideal for signal conditioning and voltage division. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it suits demanding environments. The gull-wing termination ensures secure surface-mount (SMD) assembly, while the ceramic case enhances heat dissipation.
