What is Supercapacitor?

A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor with a capacitance value much higher than other capacitors, but with lower voltage limits, that bridges the gap between electrolytic capacitors and rechargeable batteries. It typically stores 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerates many more charge and discharge cycles than rechargeable batteries.

Supercapacitors are most effective to bridge power gaps lasting from a few seconds to a few minutes and can be recharged quickly.

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.

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.

The types of capacitors that are used in the industrial end-use market segment include primarily plastic film capacitors, ceramic capacitors; aluminum electrolytic capacitors; but also to a lesser extent carbon supercapacitors and tantalum capacitors as is shown in the chart below.

What is a diode? A diode is a semiconductor device that essentially acts as a one-way switch for current. An ideal diode will have zero resistance in one direction, and infinite resistance in the reverse direction. They are also known as rectifiers because they change alternating current (AC) into pulsating direct current (DC).

Common package diodes in daily life, such as SOD123, SOD323, SOD523, SOT23, ZMM series LL34 package, ZM47**A series LL41 package, BZX55C series DO35 package and so on.

We will offer you a nice price whether it is a plastic package diode or a glass packaged diode. Let us know by info@kingtronics.com, if you are interested.
