GQCA015112CBT Description

The GQCA015112CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP package integrates 12 isolated 51.1KΩ resistors with a tight tolerance of ±0.25% and a low temperature coefficient of ±100ppm/°C, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case style and gull-wing termination enable robust surface-mount (SMD) integration, while the 100V maximum voltage rating and 0.1W power rating per resistor (1W total) make it suitable for precision analog and digital circuits.
