Tantalum Capacitors

Introduction to M39003/09-4059/TR

The M39003/09-4059/TR is a three-leaded compatible mil-spec, surface mount, tantalum capacitor. This type of component is non-polarized and electro-chemical, meaning it stores electrical charge by the conduction of two dissimilar materials. With its compatibility to standard mil-spec, this tantalum capacitor has been designed for use in army and defense switches as well as standard commercial applications.

Application Fields of M39003/09-4059/TR

The M39003/09-4059/TR capacitor is suitable for use in many power supply applications such as off-line converters, switched-mode power supplies, inverters and more. It is also used in local oscillator and frequency multipliers of television circuits and other consumer electronics. Due to its enviromentally-friendly construction, this type of tantalum capacitor is suitable for use in equipment requiring higher reliability and greater temperature stability.

Working Principle

The M39003/09-4059/TR capacitor works on the principle of a double layer capacitor or dielectric capacitor. A dielectric capacitor consists of two layers of material with different dielectric constants. These two layers are separated by a layer of air which acts as an insulating material between the two layers. When a voltage is applied across these two layers, electric field lines form within the capacitor, which allow the current to flow through the capacitor.

Inside a M39003/09-4059/TR capacitor, an electrolytic paste is spread between the anode and cathode electrodes. This electrolyte, made of organic or inorganic compounds, helps create an electrical conductive path between the two electrodes. The chemical reaction that occurs in the electrolyte produces a capacitance, which can then be used to store energy.

Conclusion

The M39003/09-4059/TR capacitor is a three-leaded compatible mil-spec tantalum capacitor manufactured for use in commercial and military settings. It is also compatible with standard mil-spec designs, meaning it can be used in a wide variety of applications. This type of capacitor works by using an electrolytic paste filled between electrodes, which creates an electrical conductive path and helps produce a capacitance.
