Tantalum capacitors have been widely utilized in electronic applications due to the wide variety of advantages they provide compared to other capacitor types. The M39003/01-6060H is one such example, particularly suited for applications requiring a high electrical capacitance with little physical size. Designed for use in military and aerospace applications, these capacitors offer a high capacitance-to-volume ratio with low dissipation and high reliability.

Design

The M39003/01-6060H capacitor is a tantalum capacitor with ultracompact dimensions, designed for use in high capacitance circuits with low power conversion requirements. They use a proprietary design and material construction that make them suitable for use in extreme high frequency and temperature applications. Internally, the M39003/01-6060H utilizes a manganese dioxide (MnO2) dielectric and an anode consisting of solid tantalum. The solid tantalum anode is etched into a cylindrical shape with two concentric cylindrical slots in order to achieve its ultra-low profile.

Electrical Characteristics

The electrical characteristics of this type of capacitor are as follows: the capacitance range is from 0.1 μF to 100 μF, the voltage is from 8 V to 100 V, the ESR range is from 0.3Ω-250Ω, and the dielectric absorption is from 25.2% to 40%. The M39003/01-6060H capacitor also features a low-distortion profile with a second harmonic distortion of less than 15 dB and a total harmonic distortion of less than 4%. Additionally, the capacitance stability of this type of capacitor is excellent, ensuring a long service life.

Applications

The M39003/01-6060H capacitor should be used in any application requiring high capacitance with lower physical size. This capacitor is ideal for use in military and aerospace applications due to its ultracompact dimensions, high reliability, low dissipation, and high capacitance-to-volume ratio. The M39003/01-6060H works well in applications such as switched-mode power supplies, DC-DC converters, dc-ac inverters, motor drives, battery charging systems, and automatic Gain Control (AGC) systems.

Working Principle

When a voltage is applied to the capacitor terminals, an electrical potential develops between the two terminal plates. This potential causes electrons to move toward one plate from the other. As the electrons accumulate on one plate, it forms an electric charge, which causes the plates to behave like two charged conducting plates. The electric field between the plates, known as the electric flux, stores energy in the capacitor, thus creating a capacitance and allowing electric current to pass between the plates. This capacitance can be changed by adjusting the amount of charge stored on the plates, or by changing the distance between the plates, thus changing the amount of electric flux between the plates.

Tantalum capacitors have several advantages which make them especially suitable for applications requiring a high electrical capacitance. Not only are they ultra-low profile, but they also have a temperature stability that is superior to other capacitor types. They are also highly reliable and their dielectric absorption is very low, meaning they are less prone to damage from repeated temperature cycles. Finally, tantalum capacitors exhibit high capacitance-to-volume ratios and hence allow for improved power conversion efficiency in space-constrained applications.
