Tantalum-Polymer capacitors are a type of capacitor composed of a tantalum anode, a polymer layer, and an aluminum oxide dielectric. They have been in use for many years, but recently have gained more attention due to their high performance and low-cost design. This article aims to explore the application field and working principle of the T543V685M050ATS065, a variant of this capacitor.
Overview of Technology
Tantalum-Polymer capacitors were first introduced in the 1980s as a low-cost alternative to traditional tantalum capacitors with an oxide dielectric. They are constructed by combining a solid layer of tantalum with a conductive polymer film, typically PTFE. This creates a combination of excellent electrical properties, including high capacitance and low equivalent series resistance (ESR). They are typically smaller in size compared to other tantalum capacitors, as well as lighter in weight.
The T543V685M050ATS065 is specifically tailored for applications requiring a high-stability continuous voltage, such as automotive systems and DC-DC power supplies. Its brushed anode construction results in a capacitance of 4.7uF per third lead and a tolerance of ±20%, making it suitable for a wide range of applications. Its operating temperature range of -55°C to +125°C also makes it an ideal choice for extreme environmental conditions.
Working Principle
Tantalum-Polymer capacitors work on the principle of electrolytic polarization. The solid tantalum anode and the polymer layer create an ionic field, with the anode being negatively charged, and the electrolyte being positively charged. This causes electrons to move from the anode to the polymer layer and creates an electric field between the two layers. This field is then used to store electrical energy and provide a high capacitance value.
The T543V685M050ATS065 specifically relies on the use of a brushed anode design to further improve the uniformity of the electric fields within the capacitor. This increases its capacitance, and energy storing capacity, by reducing the intrinsic capacitance mismatch.
Application Fields
Tantalum-Polymer capacitors are ideal for a wide range of applications. Due to their low ESR and high capacitance value, they are ideal for use in power supplies and power conditioning applications, as they can effectively store and release energy during periods of high demand. They are also well suited to high-frequency applications, as the low ESR enables them to work in the ranges of up to 30kHz.
The T543V685M050ATS065 can be used in a wide range of applications due to its brushed anode construction and high tolerance. It can be used in automotive systems as well as other high-stability sources as its excellent temperature range allows for reliable operation over an extended period of time. It is also suitable for use in power conditioning and filtering applications, as its low ESR will help to reduce ripple current.
Conclusion
Tantalum-Polymer capacitors are a type of capacitor with excellent electrical properties and a low-cost design. The T543V685M050ATS065 is a variant of this capacitor specifically tailored for applications requiring a high-stability continuous voltage. Its brushed anode construction results in a high capacitance and tolerance, making it suitable for a wide range of applications. It can be used in automotive systems, power supplies, power conditioning, and filtering applications, as well as in high-frequency applications due to its low ESR.
