Tantalum - Polymer Capacitors

T550B127K015AH4251 tantalum – polymer capacitors are used in a range of applications. These capacitors are characterized by a small size and high capacitance which makes them suitable for a variety of applications as an alternative to larger electrolytic capacitors. They are also highly reliable and have good temperature characteristics.

Types of Tantalum Capacitors

Tantalum-polymer capacitors are available in two types, polymer tantalum and solid tantalum. Polymer tantalum capacitors are constructed with a tantalum anode and a polymer organic electrolyte. These capacitors offer high capacitance in a relatively small package and are preferred in applications requiring a high value of capacitance in a small area. The solid tantalum capacitors are anodized with a conducting polymer electrolyte and feature a higher volumetric efficiency than other types of capacitors. They are commonly used in commercial and industrial applications that require a large amount of capacitance.

Application Fields

Tantalum-polymer capacitors can be used in various application fields. They are commonly used in automotive electronics such as electronic engine control modules and airbag controllers, audio and radio equipment, power management systems, medical electronics, and industrial automation. They are also used in military and aerospace applications.

Working Principle

The working principle of tantalum – polymer capacitors is based on the same principle that is used in other types of capacitors. These capacitors consist of two metallic plates that are separated by an insulating material. The capacitance is determined by the size of the plates, the insulating material\'s dielectric constant, and the distance between the plates. When a voltage is applied to these two plates, an electrical field is created that causes an electrical charge to be stored between the two plates. This charge can then be discharged through the capacitor\'s terminals to do work. The capacitance of the capacitor is proportional to the amount of charge that can be stored in it.

Tantalum-polymer capacitors are designed to be highly reliable and able to withstand high temperatures and high levels of shock and vibration. They are an excellent choice for applications where a large amount of capacitance is needed in a small area. They can also be used in applications where high levels of vibration and shock are present, due to their robust construction and ability to withstand high temperatures.
