Tantalum Capacitors: 150D225X0100B2B Application Field and Working Principle

Tantalum capacitors, otherwise known as Ta-cap or tantalum electrolytic capacitors, are electrolytic capacitors which use tantalum as their anode material, and offer certain advantages over traditional dielectric capacitors. As tantalum capacitors have an incredibly stable dielectric layer, higher levels of capacitance per unit volume can be obtained and, as a result, these types of capacitors become invaluable in high frequency and low inductance applications where very specific attributes are required. Some of the most common application fields for tantalum capacitors and the corresponding capacity value are listed below:

• Power electronics - 15-330 μF
• Primary side / high voltage - 330-1000 μF
• Defence / medical - 1500 μF or more
• RF / UV - 10-1 μF

Regarding the specific application of 150D225X0100B2B, this Capacitor model is typically used for LED lighting; in printed circuit boards; and as a passive component in fibre optic applications. This small-size component provides higher capacitance values and offers many advantages over large polarized electrolytic capacitors, including a much smaller equivalent series inductance. In addition, 150D225X0100B2B can achieve a similar capacitance level to a 4.7μF aluminum electrolytic capacitor, making them a viable option for high voltage applications.

How Tantalum Capacitors Work

Tantalum capacitors work in much the same way as many other types of electrolytic capacitors; it has three parts, two conducitng plates and an dielectric layer. The two conducting plates are typically made of nickel-plated tantalum and the dielectric layer is an electrostatic double-layer capacitor. The two plates are placed very close together and the dielectric layer is inserted between them. When a voltage is applied to the capacitor, an electric field is created which causes charge to build up on the plates, thus creating a potential difference.

Tantalum capacitors are extremely reliable due to a thick oxide layer formed on the dielectric layer which serves to protect it from wear and tear. This means that tantalum capacitors have a long lifetime and are very robust. In addition, they are much smaller than traditional capacitors due to their higher capacitance per unit volume. This makes them ideal for use in compact electronic devices such as smartphones and tablets.

Conclusion

In conclusion, the 150D225X0100B2B model of Tantalum Capacitor has a wide range of applications in LED lighting, printed circuit boards, and fibre optics. Its small size, high capacitance per unit volume, and low equivalent series inductance make it ideal for applications where space is limited and high performance is required. In addition, the build quality and life-span of the capacitor are excellent due to the thick oxide layer on the dielectric layer.
