GQCA0239R2DCT

GQCA0239R2DCT Description

The GQCA0239R2DCT from TT Electronics/IRC is a high-precision, surface-mount resistor network designed for demanding electronic applications. This 24-pin QSOP package features 12 isolated thin-film resistors, each with a 39.2Ω resistance and a tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Encased in a ceramic substrate, the network offers superior thermal stability, operating reliably across a wide temperature range of -70°C to +125°C. With a ±50ppm/°C temperature coefficient, it minimizes resistance drift under thermal stress, making it ideal for precision analog and digital systems. The gull-wing termination facilitates robust PCB mounting, while the 100V maximum voltage rating and 1W total power dissipation enhance its suitability for industrial and instrumentation applications.
