Tantalum Capacitors

Tantalum capacitors offer a high capacitance level in a compact package due to their unique structure and properties. The most common application of a tantalum capacitor is in power supply and audio applications. Their high capacitance values, fast charging/discharging capabilities, and reversible polarity make them perfect for these types of applications. Additionally, they offer the advantage of being non-polarized, which eliminates the need for a separate polarizing capacitor.

One example of a tantalum capacitor is the 13008-071KESC/HR. This capacitor features a voltage rating of 6.3V and a capacitance of 27µF. It is a standard, bipolar, non-polarized capacitor with a working temperature range of -55°C to +125°C. The ESR of the 13008-071KESC/HR is typically 6 to 12 mΩ.

Application Field

The 13008-071KESC/HR is an ideal component for use on digital boards and as part of power supply systems. Due to its fast charging/discharging capabilities, this capacitor can provide quick voltage boosts when needed. The 13008-071KESC/HR can also be used for audio applications, such as amplifiers, mixers, and EQ boards. With its low ESR and high capacitance, it can be used to filter out DC offsets and provide a clearer signal to the audio components.

Working Principle

Tantalum capacitors work by making use of the properties of tantalum metal. When a voltage is applied, the positive ions on the upper plate are attracted to the tantalum oxide on the lower plate. As the ions move, electrons from the lower plate move in the opposite direction, creating an electric current between the two plates. This current creates a charge on both the upper and lower plates, which is stored in the capacitor.

When the voltage is removed, the charge on the two plates will remain as long as the capacitor is connected to a power source. The capacitance of the device is dictated by the size of the capacitor. The larger the capacitor, the greater the capacitance. Additionally, the type of dielectric material used in the capacitor will also affect the capacitance.

Tantalum capacitors are extremely reliable components due to their high capacitance and fast charge/discharge times. They are also reliable in extreme temperatures, making them suitable for a wide range of applications. The 13008-071KESC/HR is an excellent example of a tantalum capacitor that can be used for power supply and audio applications.
