Tantalum Capacitors

Tantalum capacitors are a type of electronic component that is made up of a metal oxide sandwiched between tantalum and a conductive material. Tantalum capacitors have become popular in the world of microelectronics due to their ultra-high capacitance and low leakage current. The most common type of capacitors used in electronics today is the TAP154M035CRW.

What is TAP154M035CRW?

TAP154M035CRW is a chip tantalum capacitor that was developed by TDK in 2006. The part number stands for “Tantalum Anodic Polymer” and “035CRW” defines the capacitance and voltage rating of the capacitor. The capacitance is 35μF with a working voltage of 6.3V, a maximum voltage of 10V, and an impedance of 12 ohms. The capacitance and voltage rating can be customized by changing the last two letters of the part number.

Application Field and Working Principle

TAP154M035CRW capacitors are commonly used in high-frequency communication, power supplies, and other circuits that require low resistance and high capacitance. They are also widely used in automotive, avionics, and space applications due to their high reliability and long-term stability. The working principle of a TAP154M035CRW capacitor is simple. The capacitor is composed of two conducting sheets separated by an insulating material. When a voltage is applied to the capacitor, the dielectric material allows for a static electric field to form between the two plates. This electric field stores charge and creates a capacitance. This capacitance is measured in Farads, which is a unit of measure for the amount of electric charge that can be stored on the plates. The TAP154M035CRW capacitor is able to keep the capacitance stable due to the use of a polymer anode with a non-conductive tantalum layer to prevent oxidation. The non-conductive layer also serves as a protective shell that helps maintain a low equivalent series resistance (ESR) and leakage current. This is important because a low ESR ensures a low-loss operation, while the low leakage current prevents damage from stored energy over time.

Advantages of TAP154M035CRW

The main advantages of TAP154M035CRW capacitors include their high capacitance and low ESR, which make them ideal for high-frequency circuits and power supplies. They also offer higher operating temperatures and low leakage currents, meaning that they are more reliable than other types of capacitors. Finally, they are easy to install and are non-polar, meaning that power polarity is not affected.

Conclusion

TAP154M035CRW capacitors are a popular choice in the world of microelectronics due to their excellent capacitance, low ESR, and low leakage current. They are used in a variety of applications, including high-frequency communication and power supplies, due to their reliable performance and robust construction. While they do have some advantages over other capacitor types, they are still relatively expensive and can be difficult to find.
