Kt Kingtronics Tell You Automotive / Industrial Demand for Automotive Capacitors Has Increased

Demand for automotive chips has unexpectedly increased recently, attracting the attention of analysts and investors. 

The survey shows that demand from the automotive and industrial industries is expected to recover from the fourth quarter to 2021.

The report from Barron`s indicated that the rebound in automobile market conditions is much better than expected, mainly due to the return of Chinese automobile production to the level before the epidemic, the 100% capacity utilization rate of US automobiles and trucks, and the low dealer inventory. 

There are also signs of improvement in the trend of the business cycle industry. China, the United States and Europe's Purchasing Managers Index (PMI) for the July-September quarter all indicate that the business is beginning to expand.

Aluminum Electrolytic Capacitors

Various types of capacitors can be found throughout automotive subsystems of all types of cars, including internal combustion engine (ICE) types that now dominate the market.

For example, aluminum electrolytic capacitors are employed in convenience systems like air conditioning, window wipers and motors used for automatic windows, seats and other purposes. 

These devices also are employed in key safety and control systems like power steering, airbag controls and braking systems. 

Furthermore, aluminum electrolytic capacitors are used in engine control units (ECU) for battery controls, gas- and diesel-engine controls and electric motor drives for uses like fuel pumps and fans.

Supercapacitor Car Battery

Supercapacitors promise to play a much larger role in the EV market in the future. A major factor inhibiting the acceptance of some EVs has been their limited range.

Recent breakthroughs in supercapacitors could make them a viable and superior replacement for lithium-ion batteries, however. Conventional supercapacitors can charge up much more quickly than batteries.

Kt Kingtronics Offer Various Type of Tantalum Capacitors for Electronic Device

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.

Kt Kingtronics Advantages and Disadvantages of Tantalum Capacitors

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 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.
