It is also suitable for applications where a high capacitance density is required, such as in switched mode power supplies. The capacitor also has a wide rated range (from 6.3 volt to 63 volt) and is capable of operating at temperatures as high as 125 degrees centigrade. This makes it an ideal choice for high temperature applications.

Working Principle of TPME687K004R0018

The working principle of the TPME687K004R0018 capacitor is simple and straightforward. The capacitor consists of a tantalum pellet and a metal oxide layer, which is sandwiched between two layers of tantalum wires. When a voltage is applied across the capacitor, a current is induced in the metal oxide layer. This current creates a field that attracts ions from the tantalum pellet, forming a conductive bridge between the two layers of tantalum wire.

Once the ions have formed a bridge between the two layers of tantalum wire, the current can flow freely through the capacitor, resulting in an increase in the capacitance. Unlike other types of capacitors, the TPME687K004R0018 does not suffer from electrochemical reactions and can thus provide high reliability and long life.

Conclusion

The TPME687K004R0018 capacitor is a highly reliable and versatile component, which is suitable for a wide range of applications. Its high voltage capability and wide range of temperature makes it ideal for high temperature and power board applications. Its working principle is based on the formation of a conductive bridge between two layers of tantalum wire, providing a high capacitance density. As a result, the TPME687K004R0018 is an ideal choice for high frequency switching and storage applications.
