Tantalum - Polymer Capacitors

T545H158M006ATE055 is a type of polymer tantalum capacitor developed and designed by the capacitor manufacturer Nichicon. These components is made of a sintered anode consisting of a tantalum powder dispersed with polymers. It is commonly used in many energy saving and industrial devices, and has a wide variety of applications.

Structure

The T545H158M006ATE055 capacitor is made up of a cathode element which consists of a sinter-based powder metallurgy process. This process is used to create a porous structure and a large number of grain boundaries within the sintered material which helps to reduce the electrical conductivity of the material. The anode element, on the other hand, consists of a thin layer of tantalum deposited onto a thin film of polymeric electrolytic material.

Features

The features of the T545H158M006ATE055 are numerous. The tantalum powder used in the sinter process has an extremely high electrical insulation resistance (EIR). This feature makes it the perfect choice for devices that require high-quality electrical insulation and long-term stability. Additionally, the polymeric electrolyte used in the anode element has extremely low leakage current.It also has excellent temperature coefficient, with the rating staying nearly constant as temperatures change. This is important as it helps to ensure that devices do not suffer from accelerated aging when exposed to high temperatures.The capacitor also has a very low equivalent series resistance, which means that it is able to provide a very high efficiency, particularly when used in high power devices.

Applications

The T545H158M006ATE055 has a wide range of applications, including automotive applications, industrial controls and medical instruments. In automotive applications it is mostly used for power factor correction and power factor boosting in power electronics, as it provides excellent capacitive properties to reduce EMI levels.In industrial applications it is used to regulate motor speed and provide improved power factor control. This enables engineers to reduce the amount of power dissipated by motors when operating at high speeds, increasing their efficiency.The capacitor also has a broad range of applications in medical instruments. It is commonly used in CT (Computer Tomography) scanners, where the capacitor is used to regulate the scan speed. This allows the device to operate more efficiently and reduce the amount of energy dissipated.

Working Principle

The working principle of the T545H158M006ATE055 capacitor is relatively simple. When a voltage is applied to the anode and cathode elements, an electrostatic field is generated which attracts the electrons towards the cathode, creating a current flowing through the capacitor.As the current passes through the capacitor, energy is stored as electrostatic energy in the form of an electrical field which serves to counteract the applied voltage. This electrostatic field acts as an insulator, reducing the amount of power that can be stored.The capacitor is able to store a significant amount of energy and provide a high degree of ripple current capability without exceeding the rated current. The position of the anode and cathode determine how much energy can be stored and how quickly the energy can be returned to the circuit.

Conclusion

The T545H158M006ATE055 is a highly reliable and efficient capacitor with a wide range of applications in energy saving and industrial devices. It\'s sintered anode and tantalum end plate provide excellent electrical insulation, low leakage current and temperature coefficient, in addition to its low equivalent series resistance and ripple current capability. The capacitor\'s working principle is relatively simple and works by creating an electrostatic field to store energy that can be quickly returned to the circuit whenever required.
