1879064-5 Application Field and Working Principle

Tantalum capacitors are an essential component in modern electronics due to their high capacitance and low leakage current. The capacitors are constructed from a titanium anode, a tantalum electrolyte, and an aluminum cathode. The 1879064-5 cap is an example of a particularly popular style of tantalum capacitor.

Application Field

Tantalum capacitors are primarily used in applications where low profile and high sruface mount density are important considerations. 1879064-5 capacitors in particular are extremely popular in military and avionics applications, as their small stature lends itself to highly compact designs. Additionally, 1879064-5\'s are used in various automotive and robotic applications due to their excellent reliability under extreme conditions.

Working Principle

The 1879064-5 capacitor works on the principle of electrolytic capacitors. An alternating voltage is applied to the anode, creating an electric field in the electrolyte. This electric field draws in and stores electrons for a predetermined amount of time until the voltage is removed. This stored electrical energy is then released when a separate voltage is applied.The aluminum cathode is used to construct the majority of the capacitor body, and the electrolyte is a solution made of tantalum particles in a polypropylene matrix or paper, depending on the type of capacitor. The anode is typically a sheet of titanium dipped in tantalum, creating a uniform surface, which allows for more efficient electron transfer. The construction of the 1879064-5 capacitor provides excellent surface mount density, allowing for even higher capacitance values in a single package than other tantalum capacitors. The double dip tinning process on the anode and cathode removes the oxide layer formed when the capacitor is manufactured, providing better contact with the PCB and improved conductivity.

Conclusion

The 1879064-5 capacitor is an excellent choice for applications requiring a small, high-density design. The construction of the cap allows for exceptionally low leakage current and excellent reliability in extreme conditions. The high capacitance for the small package size and efficient electron transfer make it the ideal capacitor for a variety of military, automotive, and robotic applications.
