GQCA021801CBT

GQCA021801CBT Description

The GQCA021801CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP package features 12 isolated resistors, each with a 1.8KΩ resistance and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±50ppm/°C temperature coefficient guarantees stable performance across a wide operating range of -70°C to +125°C. With a 100V maximum voltage rating and 0.1W power dissipation per resistor, this network is engineered for precision analog and mixed-signal systems.
