绿色无铅的SMD无源晶振ABM10AIG-16.000MHZ-4Z-T3用于航空电子，Core losses – are losses from the inductors core material. Core losses are caused by Hysteresis loss and Eddy current loss, both of which are converted to heat.
Hysteresis losses are caused by the friction of the molecular domains inside core material.
These molecular domains become magnetized and polarized to the direction of the
current flowing through the conductor. As the current alternates at a frequency, the
magnetic domains must alternate polarity accordingly causing molecular friction and
dispersed in the form of heat.
Eddy currents are circulating currents that manifest in the core due the changing magnetic
field within the conductive core material. Eddy currents are a function of the frequency of
the magnetization, volume of the magnetic core, peak flux density and other various
parameters of the inductor.
Another way to categorize the losses previously described are as AC and DC sensitive components.
The DCR is purely a DC component and easiest loss to calculate. AC losses include the AC copper loss,hysteresis loss and eddy current loss. The total power loss (Watts) of the inductor is calculated using the following equation:
The AMXLA family consists of two series that are of different dimensions and different performance. As with any inductor, the AMXLA family is influenced by all the previous mentioned effects. However, the AMXLA extended temperature inductor family allows designers to operate these inductors at elevated temperature making it necessary to clearly understand how heat affects the inductor performance.

This section includes performance graphs of the AMXLA-Q1040 series. In order to minimize the size of this app note, graphs will not include all inductors in the series. The 1.0µH inductor is used as an example where the whole series cannot be illustrated.

磁芯损耗-是电感器磁芯材料的损耗。磁芯损耗是由磁滞损耗和涡流损耗引起的，两者都转化为热量。
磁滞损耗是由芯材内部分子域的摩擦引起的。
这些分子结构域被磁化并极化到流过导体的电流。当电流以某一频率交替时，则磁畴必须相应地交替极性，从而引起分子摩擦和以热的形式分散，而这些电流之中必然也少不了石英晶体的支持。
