Several key inductor parameters such as inductance, self resonant frequency (SRF), and DC resistance are listed in the data sheet. The specifications shown on this slide are specific to 25°C, although a wider operating temperature range of -55 to +155°C is offered. When DC current flows through an inductor, the component temperature will rise and the inductance will drop. The I_RMS is defined as the amount of DC current to cause inductor temperature to rise to a level specified by the manufacturer; 40°C, for instance. The I_SAT is the amount of DC current to cause inductance to drop to a level specified by the manufacturer; 30%, for instance. The inductance versus IDC and temperature rise versus IDC plot included on this slide provides a wider spectrum of I_RMS and I_SAT details. Lastly, the operating temperature is not the ambient temperature; rather, it is the inductor surface temperature which is the combined ambient and self-rise temperature under operation.
