Tantalum Capacitors

Tantalum Capacitors

Tantalum capacitors are polarised and have low voltage ratings like electrolytic capacitors. They are expensive but very small so they are used where a large capacitance is needed in a small size such as mobile phones or laptop computers. These capacitors have increasingly become an important as the demand for ever smaller electronic gadgets has grown. Columbite-tantalite – coltan for short, the ore from which tantalum is refined is mined in Australia, Egypt.

Tantalum Capacitor News II

Tantalum Capacitor has strict demand on storage conditions.  The Storing period is 10 years after manufacturing., in principle (excluding solderability).

In order to assure use, tantalum capacitors stored for over two years or processedthrough dipping molten solder prior to using preferably applied rated voltage while inherent resistance of the power supply is not more than 3Ω(For Non-solidtantalum capacitor, connect a protection resistor of 1100Ω max., in series to the capacitor), and withstand aging at 85℃ for 4-8 hours, then make measurement. The lead terminals of non-polar tantalum capacitor are reversed once every onehour and measurement of DC leakage current is also conducted on the two lead terminals respectively.

Store the Tantalum Capacitor in the package not to be exposed to direct sunlight and dust. Store in the environment holding ordinary temperature (-10~+40℃) and ordinary humidity (80%R.H. or under).If left in the atmosphere of high temperature and high humidity for a long time, solderability of the terminals is decreased and performance of the capacitors is lowered.

Suntan Tantalum Capacitor News

Tantalum Capacitor usage is increasing rapidly due to its  far superior performance than Aluminum Electrolytic Capacitors at higher frequencies. Suntan’s TS19 Dipped Tantalum Capacitor, TS20 Chip Tantalum Capacitor and TS20L Low ESR Chip Tantalum Capacitor are made to meet such increasing demand in the market.  Especially our TS19 Dipped type Tantalum Capacitor re very popular in the European and American market because of very competitive price and good quality.   You may contact us to check details with us if interested.

Our TS20 Low ESR Chip Tantalum Capacitor can be used in Radar applications. In a radar system, the first power stage requied to hold up the microwave block must be efficiently filtered from the 28V bus. When looking for the maximum-capacitance/lowest-ESR options for radar, the LOW ESR Chip Tantalum Capacitor could be the best choice  because it has the optimum combination of Capacitorance and  ESR.  You could check our TS20L Chip Tantalum Capacitor spec and advise which items you are interested if you are in the radar system design and production field.

About Tantalum Capacitor

Tantalum Capacitors are used in electronic devices including portable telephones, pagers, personal computers, and automotive electronics.  When selecting between available tantalum Capacitors, there are a number of key specifications to keep in mind when designing in a tantalum Capacitor.  These  include capacitance value, capacitance tolerance, dissipation factor, leakage current, and equivalent series resistance (ESR).  The designer must also consider the board interface requirements.  Tecate tantalum capacitors are available in radial leaded or surface mount configurations.

Capacitance is a measure of the energy storage ability of a tantalum Capacitor, given as C = K A/D, where A is the area of the electrodes, D is their separation, and K is a function of the dielectric between the electrodes. The formula yields a result in farads (F), but a farad is so large that the most commonly used values are expressed in microfarads (µf = 10-6F). 

The dissipation factor (DF) is the ratio between the resistive and the reactive part of the impedance of the tantalum capacitor submitted to a sinusoidal voltage of specified frequency. It is a measure of the losses in the capacitor.  

Leakage current is measured as the current flowing from one conductor to an adjacent conductor through an insulating layer. The leakage current in tantalum Capacitors is measured after 3 minutes at 25°C, through a 1k resistor connected in series with the capacitor, and with rated voltage applied.

Equivalent series resistance (ESR) represents the extent to which the capacitor acts like a resistor when charging and discharging. This functions via a resistive element within the capacitor model, found in both the AC and DC domains.  The lower the ESR the higher the current carrying ability of the tantalum capacitor.
