GQCA011271CBT Description

The GQCA011271CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 24-pin QSOP package features 12 isolated resistors, each with a 1.27KΩ resistance value and an exceptional ±0.25% tolerance, ensuring minimal deviation in critical circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±100ppm/°C temperature coefficient guarantees stability 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 analog and digital systems.
