GQCB012211DAT

GQCB012211DAT Description

The GQCB012211DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 23-resistor array features a 2.21KΩ resistance value per resistor with a tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 24-pin QSOP ceramic package, it offers excellent thermal stability and reliability in surface-mount (SMD) configurations. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is ideal for precision analog and digital circuits requiring consistent resistance matching.
