Tantalum Capacitors

Tantalum capacitors are among the most widely used and versatile types of capacitors available. Typically made from metal oxide, these capacitors have a variety of possible applications. They are often used in power supplies, in low voltage DC/DC conversions, in an audio circuit and other electronic applications.

M39003/01-2657H is an example of a type of tantalum capacitor. This particular tantalum capacitor is a miniature, hermetically sealed, surface mount device. It has a rated voltage of 16 volts and a capacitance of 47µF. It has an axial leaded, anodized tungsten, which is corrosion-resistant and can easily be soldered to a circuit board for use in a range of electronic applications.

Application Field

Tantalum capacitors, including the M39003/01-2657H, can be utilized for a variety of applications. This particular type of tantalum capacitor is most commonly used in applications that require low-voltage DC power supplies. They can be used in power supply systems that are connected to the mains, such as laptop adapters, AC/DC transformers and even portable devices like tablets. These capacitors can also be used for filtering and bypassing, along with decoupling and charging.

They can also be used in low voltage audio circuits, as they have low leakage current, low equivalent series resistance (ESR). This means that they can provide good sound quality and minimal distortion. The M39003/01-2657H is a perfect choice for audio circuits with low-voltage output.

In addition, these capacitors can be used in the automotive industry. They are often used to filter out noise that can interfere with the signals in the car’s electrical system. This helps to ensure the longevity and performance of the vehicle.

Working Principle

The working principle behind a tantalum capacitor is based on the property of capacitance. A capacitor is an electrical device that stores energy in the form of electric charge. This electric charge is determined by the capacitance, which is the ratio of electric charge stored in a capacitor, divided by the voltage applied across it.

In a tantalum capacitor, the capacitance is determined by the anode-to-cathode distance, the surface area, and the dielectric material between the anode and cathode. The anode and cathode are typically made from tantalum and the dielectric material is generally an oxide of tantalum, such as M39003/01-2657H which has a dielectric constant of 27. The dielectric material also plays an important role in providing the necessary insulation for the capacitor.

The capacitor stores its charge by maintaining a balanced electrical field between the anode and cathode. When a voltage is applied, an electrical current flows through the capacitor, thereby charging it up. When the voltage is removed, the capacitor slowly discharges its stored electrical charge.

Tantalum capacitors are known for their stability and reliability. They are able to maintain their capacitance and voltage over a wide temperature range, which makes them an ideal option for many electronic applications.
