GQCA031430DCT

GQCA031430DCT Description

The GQCA031430DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 24-pin QSOP package features 12 isolated resistors, each with a 143 Ω resistance value and an ultra-tight ±0.5% tolerance, ensuring exceptional accuracy in circuit designs. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±25 ppm/°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 a 100V maximum voltage rating, this network is engineered for precision analog and digital systems requiring low drift and high isolation.
