There are a number of factors that contribute to core loss. From mechanical stress to the size of the core, there can be many material constraints. The operating frequency and temperature constraints should also be considered as one reaches the saturation point and the core heating up. For suppression applications, losses are desirable at the frequency of noise to be suppressed and should be minimal at the principal signal frequency. To be safe, for power applications the design team should keep losses limited to between 300 and 1,000 mW/cm3. Engineers recommend this to help prevent thermal runaway, which can lead to thermal shock of the core.
