GQCA0256R2DCT

GQCA0256R2DCT Description

The GQCA0256R2DCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 56.2 Ω resistance value and a 0.5% tolerance, ensuring exceptional accuracy. The ceramic case style and gull-wing termination make it suitable for surface-mount (SMD) applications, while its ±50 ppm/°C temperature coefficient guarantees minimal resistance drift 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 reliability in precision circuits.
