Tantalum capacitor

Get Info From Multiple Sources. A tantalum electrolytic capacitor is an electrolytic capacitor, a passive component of electronic circuits.

It consists of a pellet of porous tantalum metal as an anode, covered by an insulating oxide layer that forms the dielectric, surrounded by liquid or solid electrolyte as a cathode. The anode is isolated from the cathode so only a very small leakage DC current may flow through the capacitor.

One of the disadvantages of having a very thin oxide layer as the dielectric is that it is not particularly robust.

Tantalum capacitor failure modes. As a result, care has to be taken when using tantalum capacitors.

We are the global leader in MnO solid tantalum technologies such as smallest case size MnO, highest temperature capabilities up to 230°C and lowest DCL product offering. The previous characteristics show how tantalum capacitors can be uniquely suited to help in modern electronics, but they are not without their quirks and there are a couple of major ones to take into account when you want to design these in.

Please view our large selection of tantalum capacitors below. The increased capacitance value differentiates the tantalum capacitor from other types of electrolytic capacitors. For surface-mount applications, AVX manufactures two styles of tantalum capacitors, both of which incorporate an MnO 2-based cathode to take advantage of its self-healing characteristics and are shown in Figure 2.

Vishay offers surface mount and through-hole tantalum capacitors for use in automotive, military, portable consumer, medical and many other applications. The polarized nature of these capacitors makes it suitable in the dc supplies. While connecting this capacitor in any circuit the polarity of the terminals need to be considered. After all, the benefits of tantalum capacitors are obvious.

The reasons for the failure of tantalum capacitors can be generally divided into two major categories of quality problems and circuit design problems of tantalum capacitors. Wet tantalum capacitors have several advantages over solid tantalum, aluminum electrolytic, and ceramic capacitors. As with all other capacitors, these advantages lead to a very specific “sweet spot” or focused area of applications where the wet tantalum capacitor is the best and preferred choice.

JINPEI tantalum capacitor manufacturers in the production of various series of tantalum capacitor, has high reliability, small leakage current, stable performance, high electric field. A tantalum, or tantalum oxide, capacitor is actually a type of electrolytic capacitor.

They are available in small SMD (surface-mount device) packaging and are polarized like aluminum oxide capacitors. However, tantalum oxide capacitors have a much higher capacitance value for their size. Descubre nuestra extensa gama. Comparamos todos los productos.

A high-performance tantalum capacitor offers designers a reliable and stable high-capacitance solution. Furthermore, they are much reliable when handled appropriately, and their shelf life is virtually limitless.

Uf 35vdc SMD (1PCs) KEMET. Condition is "New". Shipped with USPS First Class.

Summary of each regional contributor, inclusive of their yearly growth rate over the stipulated timeframe is enclosed in the document. Leaded tantalum capacitor markings: Leaded tantalum capacitors generally have their values marked in microfarads, µF.

This indicates a 22µF capacitor with a maximum voltage of 6V. Satisfying Service. Find the Newest Product. The tantalum hybrid is also the most reliable capacitor in the market.

Alternates to surface mount tantalum electrolytic. Typical values range form 0. China tantalum capacitor Supplier High Quality, Competitive Price!

They are polarized capacitors with superior frequency and stability characteristics. 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.

Wet electrolytic tantalum capacitors have on average three times the capacitance by volume than aluminum types due to higher dielectric constant and dielectric strength.
