Difference Between SMD Electrolytic Capacitors and SMD Capacitors
SMD capacitors are called multi-layer (multilayer, laminated) chip ceramic capacitors. SMD capacitors are the smallest capacitors. SMD electrolytic capacitors, SMD aluminum electrolytic capacitors, and the material used for the cathode are electrolytes, which are also The most widely used capacitors we have seen. Let's look at the difference between the two.
SMD is a processing method in the PCBA "'" processing industry. It refers to the process of applying solder paste or red glue to the components, then installing them through a placement machine, and then performing reflow soldering. Generally, the volume of the chip capacitor is smaller than that of the plug-in, which is more suitable for the development of the times. The electrolytic capacitors are relatively large in volume and capacity, and there are many types.
The disadvantage of chip electrolytic capacitors is that the dielectric loss, the capacity error is large (the maximum allowable deviation is +100%, -20%), the high temperature resistance is poor, and the storage time is long and it is easy to fail.
SMD capacitors can be divided into two types: non-polar and polar. The following two types of non-polar capacitors are the most common packages, namely 0805 and 0603; while polar capacitors are what we usually call electrolytic capacitors. Filtering, we must first consider electrolytic capacitors. Generally, we usually use aluminum electrolytic capacitors and chip capacitors the most. In a circuit composed of a circuit board, we often need to consider factors of price and performance. Different types of capacitors have different Performance advantage, no matter the capacitor of the patch or the plug-in, it is the best to choose the one that suits you.
