GQ0A021912DT Description

The GQ0A021912DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter-Small Outline Package) device features 10 isolated resistors, each with a 19.1KΩ resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±50ppm/°C temperature coefficient guarantees stable performance across a wide operating range of -70°C to +125°C. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision signal conditioning, voltage division, and impedance matching in compact designs.
