Tantalum capacitor product principle
broadcast editPressed and formed with tantalum powder, after sintering as the anode of the capacitor, and then chemically generated on its surface oxide film as a medium, and the surface to generate manganese dioxide as a cathode Because of the use of metal tantalum as a medium, there is no need to use electrolyte like ordinary electrolytic capacitors, in addition, tantalum capacitors do not need to use aluminum coated capacitor paper like ordinary electrolytic capacitors fired, so there is almost no inductance itself, but at the same time it also limits its capacityIn addition, there is no electrolyte inside the tantalum capacitor. It is very suitable for working at high temperatures, it is used in places where large-capacity filtering, such as tantalum capacitors can be seen near the CPU socket, mostly used with ceramic capacitors, electrolytic capacitors or used in places where voltage and current are not large.
