Abracon無源貼片晶振適合精密應用程序ABM11-20.000MHZ-D2X-T3，This is the continuation of the original Part I of Design Flexibility of Extended Temperature Inductors application note released earlier this year. Part I explored the use of extended temperature inductors in extreme conditions and applications where increased current was required.

This application note (Part II) dives a bit deeper and explains the DC and AC components involved to adequately derate extended temperature inductors such that safe and consistent operation through the inductor’s life is possible. 

A key aspect of derating an inductor is understanding the sources of loss or heat. Every application will have an ambient temperature which is the temperature of the surrounding environment. The ambient temperature will depend on several factors, like adjacent heat producing components, passive or active cooling of the system itself, etc. The ambient temperature of the inductor is used a baseline where other sources of heat will be additive to calculate the total inductor body/case temperature.
