編碼ECS-3525-120-B-TR超小型SMD振蕩器是高密度應(yīng)用的理想選擇，When the discussion of oscillators comes up, the same question will arise. What is the choice for performance in critical applications, MEMS (Micro-Electro-Mechanical Systems) or quartz-based oscillators? MEMS-based oscillators have been available on the market since 2005. In the last 15+ years, a handful of companies have developed MEMS-based oscillators. Today, only a few remain and the leading MEMS-based oscillator manufacturer accounts for around 1% of the total timing market. Many frequency control manufacturers private label from both companies, with the exception of ECS who does not see any value in the practice.

When selecting the oscillator for your electronic devices or communications equipment, some of the timing considerations you need to think about are: system performance, system clocking, signal quality and reference signal sources. These are the critical parameters that will decide the performance level of your product.

You may have seen another video from a MEMS manufacturer comparing MEMS oscillators to stand alone quartz crystals. It is proven that any oscillator be it quartz, SAW, ceramic, or MEMS will always outperform any standalone resonator. So, a comparison of an oscillator to a crystal is not a true test of the oscillator’s performance. In this side by side comparison, we will look at and directly compare a quartz-based oscillator with a MEMS oscillator.

當(dāng)討論振蕩器時，會出現(xiàn)同樣的問題。關(guān)鍵應(yīng)用、MEMS（微機(jī)電系統(tǒng)）或石英晶體振蕩器的性能選擇是什么？自 2005 年以來，基于 MEMS 的振蕩器已經(jīng)上市。在過去 15 年多的時間里，少數(shù)公司開發(fā)了基于 MEMS 的振蕩器。如今，只剩下少數(shù)幾家，領(lǐng)先的基于 MEMS 的振蕩器制造商約占整個時鐘市場的 1%。兩家公司的許多頻率控制制造商都是自有品牌，但 ECS 除外，ECS 在實踐中沒有任何價值。

為何這款無源晶振ABLS-LR-24.000MHZ-T能得到無線模塊的青睞？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.
在應(yīng)用中運行時，電感損耗產(chǎn)生的熱量主要有四種來源。
它們可以分為兩類，稱為銅損失和芯損失。
1. 銅損耗——這些損耗主要是由于電感導(dǎo)線的固有直流電阻(DCR)造成的。導(dǎo)線有一個已知的直流電阻，它是導(dǎo)線長度和導(dǎo)線截面積的函數(shù)(又稱量規(guī))。而石英晶振低損耗恰好能夠填補，DCR參數(shù)可以在所有Abracon電感器的數(shù)據(jù)表中找到。

從DCR的效果中耗散的能量是:
