Tantalum-Polymer Capacitors: TCJB107M002R0070 Application Field and Working Principle

Tantalum-polymer capacitors are electronic components that are widely used in signal filtering, power supply circuits, and frequency synchronization circuit applications. These capacitors are different from traditional capacitors, such as ceramic or film capacitors, in their construction and functionality. The TCJB107M002R0070 is a popular choice when it comes to these capacitors, and it is known for its efficiency and reliability while being relatively inexpensive. In this article, we will discuss the application field and working principle of the TCJB107M002R0070.

Application Field

The TCJB107M002R0070 is a high-performance tantalum-polymer capacitor that is most often used for low frequency, high voltage applications such as AC/DC power supplies, switches, and other power conversion circuits. This capacitor is designed for use in extreme environment temperatures, has a low ESR (equivalent series resistance), low leakage current, and high capacitance stability. This makes the TCJB107M002R0070 ideally suited for use in the highest efficiency, highest

reliability, and most robust power supplies and electronics. Other application areas include battery-powered and wireless devices, portable and stationary electronics, and handheld or embedded controllers. The TCJ-B107M002R0070 excels in many applications due to its low internal impedance, high ripple current capability, and robust dielectric construction.
Working Principle
The TCJB107M002R0070 is a type of solid charge capacitor that uses a unique construction of layers, consisting of a tantalum core and a solid electrolyte material. The core layer provides the capacitance value and there are welding spots between the core and terminals. More specifically, the construction of this capacitor consists of an anode layer of tantalum powder, a dielectric electrolyte layer, a silver/silver-palladium terminal, a silver/silver-palladium lead frame, and a passivation layer. This construction gives the TCJ-B107M002R0070 the ability to store a large amount of energy in a relatively small package.When a voltage is applied, the anode layer of the tantalum core acts like a sponge and absorbs the energy from the applied voltage. The absorbed energy is then released as electrons into the dielectric electrolyte, which is the second layer of the TCJ-B107M002R0070. The capacitance of the capacitor is determined by the thickness of this layer. The remaining layers act as connections, allowing the energy to flow through them while further controlling the capacitance and charge rate.
Conclusion
The TCJ-B107M002R0070 is a popular choice of tantalum-polymer capacitor due to its performance in extreme temperature environments, and its low ESR, leakage current, and capacitance stability. Its versatility and robust design make it suitable for many applications, including AC/DC power supplies, switches, battery-powered devices, and more. The working principle of the TCJ-B107M002R0070 capacitor is also key to its success, as it utilizes a unique construction of layers and components to store energy and control the charge rate.
