Notes/Important Considerations:

️· Irms: Represents the DC current that will cause a temperature rise of approximately 40°C in still air.
️· Isat: Represents the DC current that will cause a saturation of the inductor's magnetic core. This is the current at which the inductance drops significantly.
️· Note 8: Refers to the availability of tinned leads with leaded solder (if needed).
️· Datasheet Revision: Specifications are subject to change without notice. Always refer to the latest revision of the datasheet.
