WEET微特贴片铝电解电容分为：液态和固态的两种。
一般情况下表面的印字油墨颜色不同。全是进口油墨，不易掉色和脱落。液态贴片铝电解电容的印字是黑色的，固态贴片铝电解电容印字的分别有红色和蓝色两种颜色。
WEET微特铝电解电容器的结构特点：
固态电容全称为：固态铝质电解电容。它与普通电容（即液态铝质电解电容）最大差别在于采用了不同的介电材料，液态铝电容介电材料为电解液，而固态电容的介电材料则为导电性高分子。
由于固态电容采用导电性高分子产品作为介电材料，该材料不会与氧化铝产生作用，通电后不致于发生爆炸的现象；同时它为固态产品，自然也就不存在由于受热膨胀导致爆裂的情况了。固态电容具备环保、低阻抗、高低温稳定、耐高纹波及高信赖度等优越特性，是目前电解电容产品中最高阶的产品。由于固态电容特性远优于液态铝电容，固态电容耐温达260度，且导电性、频率特性及寿命均佳，适用于低电压、高电流的应用，主要应用于数字产品如薄型DVD、投影机及工业计算机等，近年来也被电脑板卡产品广泛使用。其实贴片电容本质上与引线插件式电解电容并无分别，它们之间的差别仅仅在封装或者说是焊接工艺上面。
无论是插件还是贴片式的安装工艺，电容本身都是直立于PCB的，根本的区别方式是SMT贴片工艺安装的电容，有黑色的橡胶底座。SMT的好处主要在于生产方面，其自动化程度高，精度也高，在运输途中不像插件式那样容易受损。由于欧美工厂的机械成本低而人工比较贵，所以大部分倾向于SMT贴片制造。而国内工厂的人工较便宜，所以厂商更愿意使用插件式安装。
WEET Micro Chip Aluminum Electrolytic Capacitors are Divided into Two types: Liquid and Solid(Polymer Capacitors)
Generally, the ink color of the surface is different. All imported ink, not easy to fade and fall off. The lettering of the electrolytic capacitor of the liquid chip is black, and that of the electrolytic capacitor of the WEET solid chip polymer capacitor is red and blue.
WEET Structure Features of WEET Micro SMD Ecap Chip and Solid Chip Aluminum Electrolytic Capacitor:
The full name of solid-state capacitor: solid aluminum electrolytic capacitor. The biggest difference between them is that they use different dielectric materials. The dielectric material of liquid aluminum capacitor is electrolyte, while the dielectric material of solid capacitance is conductive polymer.
As the solid-state capacitor uses conductive polymer product as the dielectric material, the material will not interact with alumina and will not explode after being electrified; at the same time, it is a solid-state product, so there will be no burst due to thermal expansion. Solid state capacitor has the advantages of environmental protection, low impedance, high and low temperature stability, high ripple resistance and high reliability. It is the highest level product in the current electrolytic capacitor products. As the solid-state capacitance is far superior to the liquid aluminum capacitance, and the solid-state capacitance has a temperature resistance of 260 degrees, good conductivity, frequency characteristics and service life. It is suitable for low voltage and high current applications, mainly used in digital products such as thin DVD, projector and industrial computer, etc., and also widely used in computer board products in recent years. In fact, the chip capacitor is essentially the same as the lead plug-in electrolytic capacitor, and the difference between them is only in the packaging or welding process.
No matter the installation process of plug-in or chip type, the capacitor itself is upright on PCB. The fundamental difference is that the capacitor installed by SMT chip process has a black rubber base. The advantage of SMT is mainly in production. It has high automation and precision. It is not easy to be damaged as plug-in type in transportation. Due to the low cost of machinery and expensive labor in European and American factories, most of them tend to SMT chip manufacturing. However, the labor of domestic factories is cheaper, so manufacturers prefer to use plug-in installation.
