Tantalum Capacitors

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of capacitor which uses tantalum metal for its anode. They are widely used in consumer electronics, automotive, military and aerospace applications and are known for their high capacitance, low cost, long life, and relatively small size. The 173D186X9050YE3 is a practical example of a tantalum capacitor.

Application of 173D186X9050YE3

The 173D186X9050YE3 is a tantalum capacitor with a capacitance of 0.001 µF. It is a surface mount capacitor with dimensions of 1.86 mm × 0.9 mm and its anode is made from tantalum. This capacitor is designed for use in consumer electronics, automotive, military and aerospace applications. It is well suited for DC-DC converters, solid state relays and other high-frequency circuits. As it is a surface mount capacitor, it has excellent mounting and thermal properties.

Working Principle

The 173D186X9050YE3 works on the principle of electrolytic capacitance. In this type of capacitor, two metal plates are used as the anode and cathode, separated by an insulating material called the dielectric. In the 173D186X9050YE3, the anode is made from tantalum and the cathode is made from a layer of manganese dioxide, which acts as the dielectric. When a voltage is applied between the two plates, an electric field forms in the dielectric, which causes an electric current to flow. This current creates an electrical charge on the plates. The amount of charge stored is proportional to the capacitance of the capacitor.

Advantages

Tantalum capacitors offer many advantages over other types of capacitors. They have a high capacitance-to-volume ratio, meaning they are smaller and lighter than other types of capacitors with the same capacitance. They are also highly stable in terms of frequency, voltage and temperature, making them perfect for high-frequency applications. They are relatively inexpensive and have a long life span, making them ideal for use in consumer products.

Disadvantages

The main disadvantage of tantalum capacitors is that they are prone to failure under certain circumstances. If the dielectric is subjected to too much voltage, it can break down. This may result in an increase in current, which can cause the capacitor to overheat and malfunction. Also, they are not recommended for use in high-temperature environments as they may suffer from thermal runaway.

Conclusion

The 173D186X9050YE3 is a practical tantalum capacitor, which is well suited for use in consumer electronics, automotive, military and aerospace applications. It has a high capacitance-to-volume ratio, making it small and light, and is highly stable in terms of frequency, voltage and temperature. However, it is not recommended for use in high-temperature environments and is prone to failure if the dielectric is subjected to too much voltage.
