· Why avoid using tantalum capacitors? From what I can find these are the main reasons to avoid tantalum capacitors in your design: Financial: Tantalum capacitors are relatively expensive even when supply and demand are balanced. Not too long ago prices went sky high due to a shortage in raw materials. Reliability: There are numerous reports of .
Tantalum capacitors use manganese dioxide for the hode layer. Compared with ceramic capacitors, tantalum capacitors do not have a decrease in capacitance due to DC bias and do not produce noise because they do not have piezoelectric characteristics. Tantalum capacitors use manganese dioxide for the hode layer. Compared with ceramic capacitors, tantalum capacitors .

· Tantalum is not the only capacitor technology in which polymer is being used to enhance stability. For frequencies approaching 1MHz, the 2mΩ ESR achieved by polymer aluminium capacitors can provide slightly higher capacitance retention without adding to design complexity. This reduced ESR does, however, have to be tradedoff against the lower .
A tantalum capacitor is one kind of electrolytic capacitor, which is a passive electrical device. It uses a capsule of spongy tantalum metal as an anode. An insulating layer of oxide covers the anode. The oxide layer further generates the dielectric. It is surrounded by a solid or nonsolid electrolyte, which serves as a hode. Tantalum capacitors are characteristics of high capacitance per ...
Our tantalum capacitors factory is loed in Zhuzhou Hunan Province, which is previously stateowned since 1970's. In 2000, Topdiode's boss bought this factory and it became private owned. We obtained Military Capacitors Certifiion GJB90018: 2009 from the Ministry of Defense of China and own two research centers and labs in this factory. We provide reliable quality for commercial tantalum ...
Tantalum capacitors have the highest capacitance per unit volume of any capacitor and are used extensively in miniaturized electrical circuitry. As the market moves to greater miniaturization, the tantalum capacitor finds increased appliion in spacesensitive and highend appliions in telecommuniions, data storage, and implantable medical devices. The use of tantalum capacitors .
use ceramic capacitors instead of tantalum capacitors in their appliions. A lowESRceramic output capacitor with a discrete series resistor can be used to replace a tantalum output capacitor. The schematic in Figure 2 shows such an implementation, using a Ωseries resistor and µF ceramic output capacitor. This series combination of parts meets the TPS76933 ESR requirements shown ...
· Only dipped tantalum capacitors on power rails had issues, and only there where they were used close to rated voltage. A 35V capacitor on a 5V rail almost never fails, but a 16V device on a 15V rail has a fair chance of popping, Replace with a regular 105C electrolytic, 20% tolerance is fine, and for a power rail you can go to the next higher capacitance and a higher voltage with very little ...
· Tantalum Capacitors in Space Appliions. There is a trend to use the commercial (automotive) grade parts is space appliions to reduce the cost of the end electronic device. In Tantalum (Ta) capacitors 50% or higher derating (reduced appliion voltage Vavs. rated voltage Vr) is the way the reliability issues with the commercial parts is ...
Ceramic Capacitor vs Tantalum Capacitors. Tantalum capacitors configured with electrodes on the bottom of the package are not susceptible to shorts, even when mounted close together facing each other. This makes it possible to further decrease set thickness to a level that is difficult or impossible to achieve with ceramic capacitors.
Tantalum capacitors are made with capacitance values ranging from 1nF all the way to 72mF and they are much smaller in size than aluminum electrolytic capacitors of the same capacitance. The voltage rating for tantalum capacitors varies from 2V to more than 500V. They have an equivalent series resistance (ESR) ten times smaller than the ESR of aluminum electrolytic .
Tantalum Polymer Capacitors are the best choice for consumer appliions with low ESR requirements such as DC/DC converters in notebooks, PDA, telecom and other appliions. The parts can be used up to 80% of rated voltage. Manufacturer's specifiions of leadfree reflow process capability, temperature range ratings, leakage current and appropriate storage/handling in accordance to the ...
· The tantalum capacitor also has excellent stability characteristics. Across a wide range of temperatures and frequencies as shown in the KEMET graphic above, the tantalum capacitor will maintain the expected capacitance better. With this stability you get more of the expected behavior of your system, which is especially important for filters; if the capacitance .
Suntan Hybrid Tantalum Capacitors. Tantalum hybrid capacitors provide very energy density and high power in devices much smaller and lighter than traditional tantalum wet, tantalum chip, aluminum electrolytic, or ceramic capacitors. The hybrid tantalum capacitor is also the most reliable capacitor in the market.

Tantalum capacitors. Tantalum capacitors are another polarized capacitor type widely used when high capacitance is needed in a small volume. Operating voltages are usually low, generally 50 volts or less, but operating lifetimes are far longer than those of electrolytic capacitors. Most tantalum capacitors are available in epoxydipped radial lead or molded epoxy surfacemount packages ...

Tantalum capacitors are typically used for reducing noise and stabilizing DC voltage in the power supply lines. When the power is turningon, high inrush currents through the capacitor can cause socalled surge current failures. For solid tantalum capacitors with manganese oxide hodes these failures result not only in a short circuit in the system, but can also cause ignition due to the ...
