GQ0A031821DAT Description

The GQ0A031821DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package features 10 isolated resistors, each with a 1.82KΩ resistance, 0.5% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case style and gull-wing termination provide robust mechanical and thermal stability, making it suitable for surface-mount (SMD) applications. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is ideal for precision analog and digital circuits.
