高性价比的石英晶体谐振器超级适合用于儿童手表ABM10-20.000MHZ-E20-T,电感器的直流电阻受环境温度和电感体固有自热的影响。图2为AMXLA-Q1040系列的DCR随环境温度升高而升高的变化情况。从图中可以看出,石英晶振和大电感值的DCR比小电感值受温度的影响更大。然而,作为DCR的百分比变化,从25°C到最大180°C的温度变化将导致DCR约60%的线性增加,而不管电感值如何。

DCR的增加通过增加直流损耗对电感的性能产生负面影响。随着额外的损耗,产生更多的自热,这是在扩展温度应用中降额电感的主要原因。因而贴片晶振也为广泛应用程序带来极大的便利。

The inductor’s DC resistance is affected by the ambient temperature and inherent self-heating of the inductor body. Fig.2 below illustrates the change in DCR of the AMXLA-Q1040 series as body/case temperature increases as ambient temperature increases. The graph shows that the DCR of larger inductance values are influenced more by temperature than smaller inductance values. However, as a percentage change in DCR, the temperature change from 25°C to the maximum 180°C will cause approximately a 60% linear increase in DCR regardless of the inductance value.

For example, the 68uH inductor has a DCR ≈ 210m? at 25°C. Adding 60% more DC resistance calculates to approximately 336m? at 180°C. For comparison, the 47uH inductor has a DCR ≈ 145m? at 25°C and a high temp DCR ≈ 232m?.
The increase in DCR negatively affects the inductor’s performance by increasing DC loss. With the additional loss, more self-heating is generated and is the primary reason for derating inductors in extended temperature applications.
