Tantalum Capacitors

T495B476K006ZTE250, also known as semi-conducting plastic capacitors, are one of the many types of tantalum capacitors. In contrast to normal electrolytic capacitors, these capacitors are not made of aluminum foil and dielectric but instead they use a combination of plastic and tantalum in their construction. This combination of materials gives the capacitor its own unique set of characteristics, making it suitable for a variety of application fields.

Application Field

The T495B476K006ZTE250 capacitors have a wide range of applications and the main ones are in the field of electronics. It is mainly used in high temperature and pressure applications such as TV sets, computer systems, high powered transformers, military and aerospace equipment, audio-visual equipment, and digital signal processing. It is also used in industrial applications such as hot air systems, oil filters, and industrial automation.

The capacitors can also be used in automotive applications where its operating temperature range and robustness makes it ideal for engine control, battery management systems, and stability control systems. Furthermore, these capacitors are also used in consumer items such as cell phones, digital cameras, and hard drives.

Working Principle

The T495B476K006ZTE250 capacitor works off of a dielectric principle similar to that of ceramic capacitors. It relies on a plastic layer between the plates to act as the dielectric. This plastic dielectric layer has a very high conductivity at high temperatures and is able to withstand high pressure. It also has a high resistivity, which means that it is able to handle high current applications as well.

The innerlayer of the capacitor is typically made of a tantalum coated substrate which helps to reduce parasitic reactance and increase life expectancy. It also has a thin oxide layer that acts as an insulation layer, preventing electrical discharge from occurring. At the same time, this layer also prevents electrolyses, meaning that the capacitor will only discharge at very high temperatures and not in normal circumstances.

This combination of the substrate and the dielectric layer makes the T495B476K006ZTE250 ideal for applications requiring a low ESR, high capacitance, and high temperature and pressure capacities. Thanks to its unique properties, it is suitable for a variety of applications and is able to offer increased reliability and performance when compared to other types of capacitors.
