Welcome to the world of Tantalum capacitors. In this article, we will explore the application field and working principle of TAJA686M004RNJ type of Tantalum capacitors.Tantalum capacitors are built using tantalum metal powder as the anode material, which is then formed into a solid anode body and then inserted into the anode cup in which the tantalum powder has been packed, resulting in an anode assembly. The anode of the Tantalum capacitor is combined with a porous polymer cathode film, and between these two components the vacuum is evacuated. The anode and cathode are, then, connected to the anode and cathode assembly, leading to the completion of the capacitor. Being a solid electrolytic capacitor, these capacitors are polarised, and as such they require the appropriate voltage or bias applied to the anode and cathode leads in order to function correctly.TAJA686M004RNJ is a type of Tantalum capacitors manufactured by Qunar Xunlong, which has high voltage, excellent temperature characteristics and high reliability for the entire working range, making it the ideal choice for all kinds of harsh environment applications such as automotive, battery power, telecom and medical industries.The TAJA686M004RNJ is built using tantalum cathode material and an anode cup filled with tantalum powder. This anode is further connected to an anode lead and then inserted into the anode cup along with a polymeric resin that serves to insulate the anode from coming into contact with the cathode. To the exterior, a non-conductive Epoxy-resin is used to ensure that the capacitor has high insulation and waterproofing properties.Due to the usage of tantalum in the construction of the TAJA686M004RNJ capacitors, they possess several important traits. Firstly, they have low equivalent series resistance or ESR as compared to other popular aluminum electrolytic capacitors. Secondly, they have excellent ripple current capacity and are able to survive extreme temperatures, ranging from -55°C to 125°C. Thirdly, they have high reliability, stability and life expectancy, making them suitable for use in extreme environment applications. Finally, the TAJA686M004RNJ type of capacitors are designed to have a low self-heating rate, making them ideal for high-power applications such as DC-DC converters, power supplies and other sensitive circuits.The working principle of TAJA686M004RNJ type of Tantalum capacitors is very simple. When the capacitor is powered, the tantalum powder\'s cathode is subjected to a positive voltage, while the anode is subjected to a negative voltage. This voltage generates an electric field between the two poles, which creates an attractive force on the electrons and ions in the surrounding gas. As these charged particles are attracted to the anode and cathode respectively, the electrical potential difference at the two ends of the capacitor drops, thus resulting in a flow of current through the capacitor. An electric field thus builds up in the capacitor, causing it to hold charges and finally form an electric current.In conclusion, TAJA686M004RNJ type of Tantalum capacitors offer a high degree of reliability and stability for high-voltage, extreme temperature and high-power applications. Their superior characteristics make them the ideal choice for uses in a range of industries, including automotive, battery power, telecom and medical. As such, Tantalum capacitors like TAJA686M004RNJ prove to be indispensable devices, when it comes to delivering superior performance and reliability.
