The WE-HCC Ferrite series is suitable for applications with frequencies up to 5MHz such as the new generation of high frequency switching regulators. The maximum operating temperature of the WE-HCC series is 125°C and it can handle continues DC currents of up to 27A without additional heat sinking. Due to the design and material, the WE-HCC series has a saturation current of 60A which is more then enough for most power supply designs. It is getting more important for certain switching topologies (currents sense) to have tight RDC tolerances especially for multiphase designs.
