Tantalum Capacitors

Tantalum capacitors, often referred to as “tantayers” or “tantalays”, are a type of nonpolarized electrolytic capacitor. They are notably smaller than traditional electrolytic capacitors, offering many advantages in terms of application, size, and efficiency. The target applications of tantalum capacitors include wearable electronics, medical systems, and communication devices. This article will discuss the 173D476X0025Y tantalum capacitor in terms of application field and working principle.

Application Field

Tantalum capacitors have a range of potential applications in consumer electronics, owing to their low profile size and good stability. They are used in a variety of consumer electronics, such as cell phones, laptop computers, digital cameras, and video game systems. As previously listed, tantalum capacitors are also used in many other devices, including medical systems, communication devices, wearable electronics, and airbags.When sizing capacitors, the size must be carefully considered. The higher the voltage rating, the larger the size of the capacitor. However, there are ultra-low profile devices available, making them ideal in space-restricted applications. The 173D476X0025Y tantalum capacitor is a small-sized device, measuring in at a height of 4.7mm and a diameter of 6mm. This small form factor makes it ideal for a wide range of applications, from device miniaturization to low-voltage DC power supply filtering.

Working Principle

The working principle of a tantalum capacitor is not unlike that of other electrolytic capacitors. In other words, when a voltage is applied across its terminals, it causes charge to flow through the electrolyte and deposits onto the anode and cathode plates.The construction of the 173D476X0025Y tantalum capacitor features an anode made of titanium substrate and a cathode made of manganese dioxide. These materials possess dielectric permittivity which helps boost the capacitor’s performance. The 173D476X0025Y is capable of withstanding currents of up to 25 A with ‘low ESR’, an acronym for ‘Equivalent Series Resistance’. This indicates its ability to limit the voltage drop and maintain the voltage applied across its terminals. It also has a high frequency response and low ESR, making it ideal for high frequency switching applications and ensures fast charging and high reliability.

Conclusion

The 173D476X0025Y tantalum capacitor is a versatile device, offering many advantages in terms of size and efficiency. Its ultra-low profile makes it well-suited for many applications, particularly those that require miniaturization. Its high frequency response and low Equivalent Series Resistance make it ideal for high-frequency switching applications, and its 25 A capability make it a suitable choice for voltage regulation.
