GQCA034991GT Description

The GQCA034991GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 24-pin QSOP package features 12 isolated resistors, each with a 4.99KΩ resistance (2% tolerance) and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). The ceramic case style and gull-wing termination provide excellent thermal stability and ease of surface-mount (SMD) assembly. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is ideal for demanding analog and digital circuits.
