GQ0A021870JDT Description

The GQ0A021870JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 20-pin QSOP package features 10 isolated resistors, each with a 187Ω resistance, 5% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic housing, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C. The gull-wing termination ensures secure surface-mount (SMD) installation, while the 0.1W power rating per resistor (1W total) and 100V maximum voltage rating make it suitable for demanding circuits.
