GQ0A027870DAT

GQ0A027870DAT Description

The GQ0A027870DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP package features 10 isolated resistors, each with a 787 Ω resistance value and a tight ±0.5% tolerance, ensuring consistent performance in precision circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±50 ppm/°C temperature coefficient guarantees stability across a wide operating range of 70°C to 125°C. With a 0.1W (1/10) power rating per resistor and a 100V maximum voltage rating, this network is engineered for low-power, high-voltage environments.
