What is Tantalum Capacitors?

Tantalum capacitors are a subtype of electrolytic capacitors. They are made of tantalum metal which acts as an anode, covered by a layer of oxide which acts as the dielectric, surrounded by a conductive cathode. The use of tantalum allows for a very thin dielectric layer. This results in a higher capacitance value per volume, superior frequency characteristics compared to many other types of capacitors and excellent stability over time. Tantalum capacitors are generally polarized, which means that they may only be connected to a DC supply observing the correct terminal polarity. The downside to using tantalum capacitors is their unfavorable failure mode which may lead to thermal runaway, fires and small explosions, but this can be prevented through the use of external failsafe devices such as current limiters or thermal fuses. Technology advances allow tantalum capacitors to be used in a wide variety of circuits, often found in laptops, automotive industry, cell phones and others, most often in the form of surface mounted devices (SMD). These surface mount tantalum capacitors claim much less space on the printed circuit board and allow for greater packing densities.

Tantalum Capacitors is the ideal products for TV, video recorder, computer, program-controlled switch, telephone, instrument, and other civil electronic complete machines.

Since Tantalum Capacitors is widely used and may manufactures was affected by the spread of the epidemic in Europe and the United States. The price for the Tantalum Capacitors may be double by the end of this year.

Therefore, if you have any inquiry on hand, it is time to share your inquiry with Kingtronics.

Tantalum capacitors are products that are small in size and can achieve larger capacitance. They were first developed by USA Bell Laboratories in 1956 and have excellent performance. Tantalum capacitors have various shapes and are made into small and chip components suitable for surface mounting. Tantalum capacitors are used not only in military communications, aerospace and other fields, but also widely applied in industrial control, film and television equipment, communication instruments and other products.

Advantage

The full name of tantalum capacitor is tantalum electrolytic capacitor, which is also a kind of electrolytic capacitor. It uses metal tantalum as the medium, instead of electrolyte like ordinary electrolytic capacitors use. Tantalum capacitors do not need to use aluminum-plated capacitor paper winding like ordinary electrolytic capacitors. The system has almost no inductance, but this also limits its capacity.

In addition, since there is no electrolyte inside the tantalum capacitor, it is very suitable for working under high temperature. This unique self-healing performance guarantees the advantages of long life and reliability. Solid tantalum capacitors have excellent electrical properties, a wide operating temperature range, various forms, and excellent volumetric 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. The oxide film dielectric of this layer is integrated with one end of the capacitor and cannot exist alone. Therefore, it has a very high working electric field intensity per unit volume, and has a particularly large capacitance, that is, a very high specific capacity, so it is particularly suitable for miniaturization.

Disadvantage

The capacity is smaller, the price is more expensive than the aluminum capacitor, and the withstand voltage and current capability are weak. It is used in places with high-capacity filtering. For example, tantalum capacitors can be seen near the CPU socket. They are mostly used in conjunction with ceramic capacitors and electrolytic capacitors or used in places where voltage and current are not high.

Filtering performance

The performance of tantalum capacitor is excellent. It is a product with a small size and a larger capacitance among the capacitors. There are few competitors in the use of power supply filtering and AC bypass.

Tantalum electrolytic capacitors have properties such as power storage, charging and discharging, and are mainly used in filtering, energy storage and conversion, symbol bypass, coupling and decoupling, and time constant components. Please pay attention to its performance characteristics in the application. Correct use will help to give full play to its functions. For example, consider the working environment of the product and its heating temperature, and take measures such as derating use. Improper use will affect the working life of the product.

In the working process of tantalum capacitors, it has the performance of automatically repairing or isolating the defects in the oxide film, so that the oxide film medium can be strengthened at any time and restore its proper insulating ability without continuous cumulative damage. This unique self-healing performance guarantees the advantages of long life and reliability.

Yageo said that due to the 5G driving demand for tantalum capacitors and the price increase effect driven by the epidemic, it is estimated that the price of tantalum capacitors will double by the end of this year.

Tantalum capacitors and MLCC, aluminum electrolytic, and film capacitors are the four commonly used capacitors in the industry. Tantalum capacitors have high density, high reliability and stability, and wide temperature range characteristics. They are widely used in industrial and consumer markets. According to statistics, in 2019 The global market size is approximately USD 1.6 billion.

Tantalum capacitors are widely used in fast charging devices for mobile phones due to their stable output and small size. In addition, tantalum capacitors are also ideal choice for 5G devices with large outdoor temperature changes and high requirements for service life and reliability. With the start of 5G commercial use, 5G base stations will be deployed in large numbers, which will increase the demand for tantalum capacitors.

At present, international tantalum capacitor manufacturers represented by the US companies VISHAY, KEMET, and AVX dominate the international tantalum capacitor market. However, due to the spread of the epidemic in Europe and the United States in the second quarter, the production capacity of overseas manufacturers was affected, and the gap between supply and demand expanded. AVX took the lead in May this year increase the price by 10%-15%. Yageo stated that the price increase of some items will take effect from May until the end of September; since manufacturers increased their prices, the surrounding spot retail sales have increased by 2 to 3 times, and the industry predicts that the price increase may be doubled by the end of this year. 

It does not seem that suppliers are alarmist. Under the influence of the epidemic and many uncertain factors in the international supply chain, the price surge of tantalum capacitors may intensify.

Yageo is expected to fully incorporate KEMET into the consolidated financial report from July.

The legal person pointed out that 5G drives the demand for tantalum capacitors, and the price increase effect driven by the epidemic, it is estimated that the price of tantalum capacitors will double by the end of this year.

Affected by the COVID-19 (coronavirus disease 2019) epidemic, the progress of resumption of work and the supply of tantalum capacitors are in short supply,

The legal person pointed out that some items have increased in price, and the new pricing will take effect from May until the end of September; since manufacturers have increased their prices,

The surrounding spot retail price has risen by 2 to 3 times, and the industry predicts that the price increase may double by the end of this year.
