Tantalum capacitors SMD

SMD tantalum capacitors

Tantalum capacitors have been in use since around the middle of the 20th century. They are mainly famous for their incredible reliability and capacitive density. For this reason, they are often used in the production of equipment used for special purposes. Great examples are military computers and electronics, electronic equipment in aviation systems, biotechnology solutions (medical implants), advanced notebooks and telephones. This type of capacitor is an essential electronic component consisting of two covers made of conductors and one dielectric separating them.

The tantalum capacitors that you can buy in this category of the Botland store are made of sintered tantalum on which a thin layer of dielectric (Ta2O5 - tantalum pentoxide) is formed. The second layer is made of manganese dioxide (MnO2). Manganese Dioxide is an inexpensive semiconductor material that is both very durable and self-healing. As a result, the SMD tantalum capacitor is very reliable. However, it is worth remembering that in extreme conditions, at very high temperatures and in the presence of oxygen, it can cause ignition - therefore, appropriate precautions should be taken.

Tantalum electrolytic capacitors – practice use and phenomenal parameters

Tantalum capacitors are sometimes called solid electrolytic capacitors. This is due to their construction. These capacitors are used for filters, decoupling signals or energy storage. They are also perfect for systems used in aviation, military electronics, advanced medical implants, laptops, and mobile devices. They are also commonly used in various industrial automation and control systems.

The introduction of SMD tantalum capacitors to the widespread use was somewhat revolutionary. This design directly contributed to the more effective process of miniaturization of all devices. Although these capacitors are very compact, they offer a very large capacity. This is due to the highest level of capacitive density recorded against all types of capacitors in general. Due to this property, tantalum capacitors are perfect as components for surface mounting (SMD). An additional advantage that should be taken into account when choosing the right capacitor is the relatively low price of these devices (especially in the context of very high energy efficiency).

Various types of tantalum capacitors

In this category you will find various SMD tantalum capacitors. Particular devices differ mainly in their maximum capacity. There are tantalum capacitors with capacities of 1 µF, 4.7 µF, 10 µF, 22 µF, 47 µF and 100 µF.

When choosing, take into account the overall size of the device. There are capacitors with sizes marked as SMD A, SMD B and SMD C. The rule is that the closer the letter is to the beginning of the alphabet, the smaller the size of the element. The permissible voltage for commonly used SMD tantalum capacitors is 10 V or 16 V.
