GQCA015902DBT Description

The GQCA015902DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP package features 12 isolated resistors, each with a 59K Ohm resistance and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case style provides superior thermal stability, while the gull-wing termination enables reliable surface-mount (SMD) assembly. With a 1W total power rating (0.1W per resistor) and a ±100ppm/°C temperature coefficient, this network maintains stable performance across a wide temperature range (70°C to 125°C). Its 100V maximum voltage rating and isolated (ISOL) circuit design make it ideal for high-voltage or noise-sensitive environments.
