Tantalum electrolytic capacitors Tantalum capacitors are small-capacity capacitors that can achieve large capacitance, and have excellent performance. Tantalum capacitors come in a variety of shapes and are made into small and chip components suitable for surface mounting.
1) Metal case with insulated sleeve,Glass sealed,Tubular,
2) Radial leads,heteropolarity.
3) Low Leakage current, stable and excellent performances,
4) high reliability and long life.
Tantalum capacitors have a very high working electric field strength and are larger than any type of capacitor to ensure its miniaturization.
Tantalum capacitors can easily obtain large capacitance, and there are few competitors in power filtering, AC bypass and other applications.
Tantalum capacitors have unidirectional conductivity, which is the so-called “polarity”. The current should be applied in the positive and negative directions of the power supply. The anode (positive) of the capacitor is connected to the “+” pole of the power supply and the cathode (negative electrode) is connected to the If the “-” pole is connected incorrectly, not only will the capacitor fail to function, but the leakage current will be very large, the core will heat up in a short time, and the oxide film will be destroyed immediately.
The working voltage of tantalum capacitors has a certain upper limit of the average value, but the shortcomings in this respect are not important for the transistor or integrated circuit power supply.
Tantalum capacitors have the ability to store electricity and charge and discharge.
The full name of tantalum capacitors is tantalum electrolytic capacitors, which are also a type of electrolytic capacitors. Metal tantalum is used as the dielectric. Unlike ordinary electrolytic capacitors, which do not use electrolytes, tantalum capacitors do not need to be coated with aluminum-coated capacitor paper. System, there is almost no inductance itself, but this also limits its capacity. In addition, because there is no electrolyte in tantalum capacitors, it is suitable for working at high temperatures. This unique self-healing performance guarantees its advantages of long life and reliability. Solid tantalum capacitors have excellent electrical properties, a wide operating temperature range, various forms, and excellent volume efficiency. They have their unique characteristics: The working medium of tantalum capacitors is a very thin tantalum pentoxide film formed on the surface of tantalum metal. This layer of oxide film dielectric is integrated with one end of the capacitor, which cannot be left alone. Therefore, it has a very high working electric field strength per unit volume, and has a particularly large electric capacity, that is, a very high specific capacity, which is particularly suitable for miniaturization.
Tantalum capacitors are not only used in military communications, aerospace and other fields, but the application range of tantalum capacitors is still used in industrial control, film and television equipment, communication instruments and other products.
