GQCA027870BBT Description

The GQCA027870BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 787Ω resistance value and an ultra-tight 0.1% 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 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision analog and mixed-signal systems.
