GQ0A021691GGT Description

The GQ0A021691GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 1.69KΩ resistance value and a tight 2% tolerance. The device operates over a wide temperature range (70°C to 125°C) with a low ±50ppm/°C temperature coefficient, ensuring stability in demanding environments. Encased in a ceramic substrate, it offers superior thermal management and durability. Rated for 1W total power dissipation (0.1W per resistor) and 100V maximum voltage, it is ideal for surface-mount (SMD) designs requiring reliable signal conditioning or voltage division.
