Tantalum Capacitors

M39003/09-0158 is a type of tantalum capacitor. This capacitor is an electrolytic type which utilizes an anode made from tantalum metal, and containing a oxide-based electrolyte, as its core. As with other electrolytic capacitors, the M39003/09-0158 utilizes a pair of aluminum foils that sandwich the tantalum anode to form the capacitor construction. This type of capacitor offers high capacitance per volume due to the very thin oxide film created on the surface of the tantalum anode.

Application Field

The M39003/09-0158 has many uses in various applications. Its high capacitance per volume ratio makes it highly suitable for use in high frequency and high-speed operations. It is often used in switch-mode power supplies and in resonance circuits in oscillators and timer applications. It can also be used in radio receivers, amplifiers, power supplies and other circuits that require stable operation.

Working Principle

The working principle of the M39003/09-0158 is similar to that of other electrolytic capacitors. It operates by using a conductive dielectric material, such as a tantalum oxide, that is formed on the surface of the tantalum anode. This dielectric material separates the anode from the cathode, which is the aluminum foil. When a voltage is applied across the capacitor, the dielectric material allows current to pass through, resulting in a storage of energy.

When the capacitor is charged, the voltage creates an electric field across the anode and cathode, and this creates an electrostatic force that charges the dielectric. The capacitor\'s capacitance is determined by the area of the dielectric, and the voltage across it. As the voltage increases, the capacitance increases proportionally. When the voltage is removed, the stored energy is released and the capacitor returns to its discharged state.

Conclusion

The M39003/09-0158 tantalum capacitor is a versatile and reliable component that can be used in a wide variety of applications. Its high capacitance per volume enables it to be used in high frequency and high-speed operations. The working principle of the capacitor is based on the creation of an electric field between the anode and cathode, which is responsible for the energy storage within the dielectric material.
