Tantalum capacitor - Wikipedia

Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, its name comes from Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant.

What does this capacitor symbol mean? - Part ...

Oct 10, 2018· I assume that this is a 10uF 35V tantalum cap and that the cross-hatches indicate some kind of transient voltage suppression in the device (the component goes from a trace to ground), but I can't find the symbol on-line and am reluctant to simply substitute a common tantalum capacitor until I know what the symbol means.

The Ultimate Capacitors Guide: Learn How To Use Them

The capacitor polarity is designated by the ' + ' symbol on one of the capacitor pins, meaning that the higher voltage should be connected there. What is even more interesting is that there are capacitors in which you can adjust to change the capacitance value. It is called a variable capacitor. Here are how the symbols are typically drawn:

How to Read a Schematic - learn.sparkfun.com

Capacitors. There are two commonly used capacitor symbols. One symbol represents a polarized (usually electrolytic or tantalum) capacitor, and the other is for non-polarized caps. In each case there are two terminals, running perpendicularly into plates.

Tantalum Capacitor | Electronics Notes

Tantalum capacitor failure modes. One of the disadvantages of having a very thin oxide layer as the dielectric is that it is not particularly robust. As a result, care has to be taken when using tantalum capacitors. Tantalum capacitors are reliable provided they are operated within their specification limits.

Tantalum Capacitor DATASHEET(..

tantalum capacitor, a mispolarizing is permissible up to the values indicated in reversal voltage. The tantalum capacitor is a polar electrolytic capacitor. The anode is a porous body of sintered tantalum powder. A layer of tantalum oxide is formed over the whole sintered anode surface by an electrolytic oxidation process.

KO-Conductive-Polymer - kemet.com

The KEMET Organic Capacitor (KO-CAP) is a tantalum capacitor with a Ta anode and Ta2O5 dielectric. A conductive organic polymer replaces the traditionally used MnO2 as the cathode plate of the capacitor. This results in very low ESR and improved capacitance retention at high frequency.

Capacitor Codes & Markings | Electronics Notes

For leaded tantalum capacitors the polarity markings indicate the positive lead. A "+" sign is placed close to the positive lead. When new, a further polarity making may be used because it may be seen that the positive lead is longer than the negative one.
