- [行业资讯]为何这款无源晶振ABLS-LR-24.000MHZ-T能得到无线模块的青睐？2022年10月19日 11:00
- 为何这款无源晶振ABLS-LR-24.000MHZ-T能得到无线模块的青睐？There are four main sources of heat generation from inductor losses when operating in an application.
They can be categorized into two groups referred to as copper losses and core losses.
1. Copper losses – these are losses primarily due to the inherent DC resistance (DCR) of the inductor’s wire. The wire has a known DC resistance which is a function of the wire length and the cross-sectional area of the wire (aka gauge). The DCR parameter can be found in all the Abracon inductor’s datasheets.
The power dissipated from the effects of the DCR are:
There is, however, a frequency component to copper loss due to what is called the skin effect and
proximity effect. The skin effect is where the electrons traveling through a conductor’s magnetic field are forced towards the outside ‘skin’ of the wire. As frequency increases, the skin effect strengthens causing AC resistance to increase.
The proximity effect further reduces current (increases resistance) due to magnetic fields of adjacent wires within the coil. Inductor coils with more turns and tightly packed windings will be affected greater by the proximity effect. Power dissipation from these AC effects is calculated by taking the RMS value of only the change in current seen by the inductor (sometimes called ripple current), squaring the RMS value and multiplying by the equivalent AC resistance.
AC resistance (ACR) is a difficult parameter to document due to its dependency on so many factors.
Abracon suggests that designers use an empirical method of measuring the copper loss from AC sources like the skin and proximity effects.
在应用中运行时，电感损耗产生的热量主要有四种来源。
它们可以分为两类，称为铜损失和芯损失。
1. 铜损耗——这些损耗主要是由于电感导线的固有直流电阻(DCR)造成的。导线有一个已知的直流电阻，它是导线长度和导线截面积的函数(又称量规)。而石英晶振低损耗恰好能够填补，DCR参数可以在所有Abracon电感器的数据表中找到。
从DCR的效果中耗散的能量是:
