Additional Details

The PC44 ferrite material from TDK is specifically formulated for applications requiring high performance and efficiency in power conversion circuits. Key electrical characteristics include saturation flux density (Bs), core loss (Pcv), permeability (µi), and Curie temperature (Tc). The saturation flux density determines the maximum energy that can be stored in the core, while the core loss affects the efficiency of the magnetic component. The permeability influences the inductance value, and the Curie temperature specifies the temperature above which the material loses its ferromagnetic properties. The DS9.5/5.3 core dimensions are critical for determining the winding area and the overall size of the magnetic component. The AL value (inductance factor) is also an important parameter that specifies the inductance per turn squared. Proper selection of the core material and dimensions, along with appropriate winding design, is crucial for achieving optimal performance in power conversion applications. The E421711.6KG designation is likely related to a specific packaging configuration or ordering code, possibly indicating the quantity of cores per package or a specific handling procedure.
