GQ0A018451DAT Description

The GQ0A018451DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 10 isolated resistors, each with a resistance value of 8.45KΩ and a tight tolerance of ±0.5%, ensuring exceptional accuracy. The ceramic case style and gull-wing termination enable reliable surface-mount assembly, while the ±100ppm/°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 digital circuits.
