Tantalum Capacitors

Tantalum capacitors are one type of electrolytic capacitor, aenergy-storage components manufactured from a tantalum and electrolyte compound within a metal case. They offer many advantages over other types of capacitors and are suitable for many applications. The primary benefit of a tantalum capacitor is its high volumetric efficiency meaning that, for a given capacitance, the physical size of a tantalum capacitor is much smaller than competing types. This is because the voltage rating of tantalum capacitors remains constant over their entire lifetime under normal operating conditions.

The part code 299D685X9016BB6E3 is a tantalum capacitor with the following characteristics:

• Capacitance: 680 uF
• Voltage rating: 6.3V
• Diameter: 16 mm
• Height: 9 mm
• Terminals: Through-hole
• Tolerance: 10%

The main application field of this tantalum capacitor is for use in high-reliability circuit designs, where space constraints allow larger percentage availability of a capacitor\'s capacitance relative to its own volume. The capacitors are usually used as input/output filtering capacitors, especially in switch mode power supplies, as well as high frequency SMPS and various DC/DC converters.

The working principle of a tantalum capacitor is relatively simple. It uses the phenomenon of capacitance, which is the ability of a substance to store an electrical charge due its dielectric properties. In the case of a tantalum capacitor, the dielectric material is a highly capacitative material called tantalum pentoxide which is sandwiched between two electrodes. When a voltage is applied across the electrodes, the negative charge accumulates on the cathode while the positive charge accumulates on the anode. This creates an electric field, which is responsible for the stored energy within the capacitor.

The key characteristics of a tantalum capacitor are its high capacitance, low equivalent series resistance (ESR) and low leakage current. The low ESR helps reduce ripple currents and therefore reduces electromagnetic interferences, while the low leakage current helps to maintain the capacitance over its lifetime. In addition, these capacitors have excellent frequency characteristics, which make them ideal for high frequency applications.

In conclusion, a 299D685X9016BB6E3 is a type of tantalum capacitor with a capacitance of 680 uF, a voltage rating of 6.3V, a diameter of 16 mm, and a height of 9 mm. This type of capacitor offers many advantages such as high volumetric efficiency and good frequency characteristics. Its main application fields include high-reliability circuit designs and SMPS and DC/DC power converters. Its working principle is based on the phenomenon of capacitance.
