The saturation current is the current at which the initial inductance drops indicated by an * which are +/- 30%. approximately 30% at the stated ambient temperature. This current is determined 6. Parts shown in bold are standard catalog parts and are available through sample by placing the compnent in the specified ambient environment and applying a short stock and distribution. Parts in lighter font are available but are not necessarily held duration pulse current (to eliminate self-heating effect) to the component. in sample stock or distribution and lead times may be longer.
