Tantalum capacitors are a specialized capacitor used in a variety of applications across different industries.
The TAZV686K025LBSB0024 is a high-reliability electrolytic tantalum capacitor and is used in a wide range of applications. This article will provide an in-depth look at the application fields and working principles of the TAZV686K025LBSB0024.

Types of Tantalum Capacitors

Tantalum capacitors are available in two varieties: solid and wet. Solid tantalum capacitors employ manganese dioxide (MoO) as their dielectric material, while the wet tantalum capacitor’s dielectric material is a solution of tantalum pentoxide in alcohol or acetate. The TAZV686K025LBSB0024 is a solid, radial lead, axial leaded, organic solvent resistant and conformally coated capacitor. This type of capacitor is often referred to as a “non-solid” capacitor.

Structure of a Non-Solid Tantalum Capacitor

A non-solid tantalum capacitor is comprised of three components: a cylindrical tantalum anode, a dielectric layer and a cathode. The anode is made from a powdered tantalum press-fused into a cylindrical shape. The dielectric layer is made from a sheet of manganese dioxide which is then soaked in an electrolyte solution. The cathode is made from a film of copper alloy and is coated with a conductive layer. The three components of a non-solid tantalum capacitor are bathed in an electrolyte solution which acts to maintain the structural integrity of the capacitor.

Application Fields

The TAZV686K025LBSB0024 is well-suited to a variety of applications, including embedded systems, telecoms, high-reliability systems, communications systems, automotive power supplies, and power supplies. The TAZV686K025LBSB0024 is particularly useful in high-reliability systems due to its excellent temperature characteristics, low ESR, and long life span. This capacitor is also well-suited to mobile phones, speakers, and cameras given its ability to withstand high temperatures and humidity. Additionally, the TAZV686K025LBSB0024 is ideal for use in connection with power supplies, DC-to-DC converters, and especially in automotive applications where the capacitor must maintain its electrical properties in extreme temperature and vibration conditions.

Working Principle

The working principle of tantalum capacitors is based on an electrochemical action. When a voltage is applied across the capacitor, an electric field forms within the dielectric material, which then polarizes atoms and the substances they contain. Electrons then flow freely within these substances, resulting in a current being generated. This current is then stored in the capacitor as electrical energy.The TAZV686K025LBSB0024 specifically works when a voltage is applied across its terminals. When the voltage is applied, an electric field forms between the anode and the dielectric layer. This electric field will cause ions to be attracted to the anode, resulting in a polarized dielectric and a current flow. The current then flows to the cathode, completing the circuit. This current is stored in the capacitor, allowing the capacitor to work as a power storage device.

Conclusion

The TAZV686K025LBSB0024 is a high-reliability capacitors specifically designed for use in a variety of different applications. This capacitor is well-suited to power supplies, mobile phones, speakers and cameras due to its high-temperature and humidity proofing capabilities. The TAZV686K025LBSB0024 works by forming an electric field between its anode and the dielectric layer, resulting in the flow of current. This current is then stored in the capacitor as electrical energy, allowing it to function as a power storage device.
