GQCA0393R1DCT

GQCA0393R1DCT Description

The GQCA0393R1DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP (Quarter Small Outline Package) device integrates 12 isolated resistors, each with a 93.1 Ω resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy. The ceramic case and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±25 ppm/°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 (1W total), this network is engineered for precision analog and digital circuits.
