Tantalum capacitors are generally considered to be the most reliable of all capacitor types due to their extremely low ESR (Equivalent Series Resistance) and low melting point. They are also known to have a very high capacitance compared to their physical size. The construction of tantalum capacitors is incredibly reliable, and they are designed to be used in virtually any electrical system, from consumer electronics to military electronics applications.

The 299D475X9050DB1E3 tantalum capacitor is a surface mount device, with the case size being 4.75mm long and 2.5mm wide. It is rated at 10V with a capacitance of 47uF 25V (micro Farads). It is also stamped with a tolerance of “± 20%”, which means that within 20% of the stated value, the capacitance will remain close to and within the stated value. This is very important for precise and reliable performance.

Tantalum capacitors are polarized every time, so when installing these capacitors, one lead is marked black to help identify the polarity. If these capacitors are installed in the wrong direction, they can fail immediately or, even worse, they can become unstable, resulting in a decrease of their useful life span. That is why it is very important to pay close attention to the polarity when installing these surface mount capacitors.

In terms of their electrical parameters, Tantalum capacitors have a very high self-healing capability, having a very low leakage current and an exceptional ability to survive power cycling even when operating at the highest frequencies. They also have an extremely low ESR and high accuracy at lower voltages.

The 299D475X9050DB1E3 tantalum capacitor is mainly used in high-frequency radio applications, power signal filters, and switching circuits due to their small size and low power dissipation. Furthermore, the reliable performance and efficient performance of this type of capacitor also make it ideal for medical applications, computers, and automotive applications.

Regarding its working principle, it works in a similar way to other capacitor types. Incoming AC voltage, or incoming current, causes a separation of electrical charges and when the opposite charges meet on separate plates, an electrostatic field is created, and this achieves the purpose of the capacitor. In the case of a tantalum capacitor, the anode or positive terminal is made out of a highly reactive oxide material, otherwise known as a “tantalum pentoxide”. The anode also has a coating made from a metal oxide type electrolyte.

In summary, the 299D475X9050DB1E3 tantalum capacitor is still one of the most reliable types of capacitors, and still one of the most widely used due to its numerous advantages, such as low power dissipation, low ESR, and high accuracy. This type of capacitor is mainly used for high-frequency radio applications, power signal filters, and switching circuits because of its size and power saving characteristics. We have looked at its application fields and its working principle.
