GQCA034870GT

GQCA034870GT Description

The GQCA034870GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 24-pin QSOP package features 12 isolated resistors, each with a 487Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding environments. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±25ppm/°C temperature coefficient guarantees minimal resistance drift across the 70°C to 125°C operating range. With a 100V maximum voltage rating and 0.1W power rating per resistor (1W total), this network is ideal for isolation and signal conditioning in analog and mixed-signal circuits.
