Tantalum Capacitors

A Tantalum Capacitor, also known as a TaCap, is a type of capacitor originally developed to offer a high capacity, high voltage, low leakage, low ESR capacitance solution. Its metallic components are made of pure tantalum, with tantalum lime or manganese dioxide used as an electrolyte. The TRJB685M025RRJ is one of the most widely used Tantalum Capacitor types.

TRJB685M025RRJ Application Field

The TRJB685M025RRJ is a built-in high reliability micro tantalum electrolytic capacitor, commonly used in automotive, industrial and aerospace applications. It is designed for applications that require both high reliability and high capacitance values, such as engine control units, motor control units, sound systems, automotive safety systems and other applications that require a high voltage and low ESR.

TRJB685M025RRJ Working Principle

The TRJB685M025RRJ Tantalum Capacitor works through a process called electrolytic oxidation. This process works by applying electrons in direct current (DC) to a dielectric material, which causes an oxidation of the tantalum material. The oxygen and tantalum then form a stable film on the surface of the electrode that gives the capacitor its electrical properties. This capacitor also has a temperature range of -40°C to +125°C, a DC leakage current of 0.1∙C/uF or less and a dissipation factor (DF) of 0.2%.The TRJB685M025RRJ can be used in different types of applications, depending on the capacitance and voltage rating. These include AC filter capacitors, signal line filtering, rectifier smoothing, power line suppression, power supply noise cancelling, and stability capacitors. Additionally, these capacitors can also be used in surge protectors and other applications that require very low ESR and high frequency characteristics.

Capacitor Construction

The TRJB685M025RRJ capacitor is constructed in a flip chip style, which is a type of electrical mounting technique in which individual integrated circuits (ICs) are mounted directly to a PCB or other substrate, with the help of a foundation substance. The chip is then flipped over and the connection points pass through the foundation material, allowing for the connection points to be electrically connected to the substrate of the circuit board.The construction of this capacitor also involves a two-part housing made of a metal shell for the internal electrodes, and a hermetic, corrosion-resistant sealant for the exterior of the capacitor. The capacitor also has three electrodes: one for the negative lead, one for the positive lead and one for the dielectric material.

Advantages and Disadvantages of the TRJB685M025RRJ Capacitor

The benefits of opting for a TRJB685M025RRJ capacitor for your application are that it is considered to be extremely reliable and is capable of handling high voltage and temperature. It also has low ESR, high capacitance values and can be used in audio, power supply and other applications.On the other hand, the TRJB685M025RRJ capacitor is not suitable for use in high temperature or high humidity environments. It can also have a high level of leakage current, which can affect the performance of the capacitor. In conclusion, the TRJB685M025RRJ is one of the most popular types of Tantalum Capacitor. Its wide application range and ability to handle high voltage and temperature make it a great choice for many types of applications. However, its disadvantages should also be taken into consideration when selecting this capacitor for your project.
