GQCA012492DBT Description

The GQCA012492DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 24.9KΩ resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case style provides robust thermal and mechanical stability, while the gull-wing termination enables reliable surface-mount (SMD) assembly. With a ±100ppm/°C temperature coefficient, it maintains stable performance across a wide operating range of -70°C to +125°C, making it suitable for harsh environments. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating further enhance its versatility in precision analog and digital systems.
