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.

Bridge rectifier circuit is the most used of a rectifier circuit. 
Such a circuit, simply by adding two diodes connected to port "bridge" structure, it has the advantage of a full-wave rectifying circuit, while a certain extent, overcome its shortcomings.

Kingtronics produce and sell many different kinds of bridge rectifiers. 
Bridge rectifier are widely used in LCD TV, CRT color TV sets, monitors, speakers, energy-saving lamps, microwave ovens, printers, set-top boxes, small household electrical appliances and other fields.
