How to distinguish ceramic capacitor from
tantalum electrolytic capacitor? In fact, it is easy to identify, the two raw materials are different: it is well known that tantalum electrolytic capacitors use tantalum as a carrier, and ceramic capacitors use porcelain as a medium. The capacitance of ceramic capacitors is smaller than that of tantalum electrolytic capacitors. Tantalum electrolytic capacitors can be reduced to small capacity, but the performance of ceramic capacitors is slightly worse when they increase to large capacity. Compared with tantalum electrolytic capacitor performance slightly better than ceramic capacitor.
The two applications are not quite the same: tantalum electrolytic capacitors can be used for coupling, filtering vibration bypass and other electronic circuit work in a large cyclical field, while ceramic capacitors are mostly used in high-frequency circuits. The main differences between tantalum electrolytic capacitors and ceramic capacitors are that under the same capacity, tantalum electrolytic capacitors have relatively small volume, lower equivalent series resistance than ordinary electrolytic capacitors, long service life, and high temperature resistance. However, because the key raw material of tantalum electrolytic capacitors is tantalum, it is very expensive in the market, so the price of tantalum capacitors is also very expensive, and they are usually used in advanced products. Ceramic capacitors of ordinary household appliances are more appropriate regardless of price or use.
The capacity of ceramic capacitors is usually not too large, while tantalum electrolytic capacitors can achieve, but also more decouple. Ceramic capacitors are relatively affordable, especially the ceramic capacitors with flat plug-in are the cheapest, and many conventional household appliances can be used. In recent years, with the continuous upgrading of technology, the capacity of ceramic capacitors has become larger and larger. Besides 4UF ceramic capacitors, ceramic capacitors are gradually stepping into the mainstream, replacing tantalum electrolytic capacitors.
