M39003/01-5249 Capacitors

Tantalum Capacitors

Tantalum capacitors are a key component in many electrical and electronic systems and are used in a variety of applications. This guide explains the principles of the M39003/01-5249 series of tantalum capacitors and the applications in which they are used.

Construction of the M39003/01-5249

The M39003/01-5249 is a surface mount, polarized tantalum capacitors, designed to meet critical performance requirements for high reliability electronics. It is made up of two basic components, a solid tantalum pellet and one or two layers of an electrolytic solid dielectric material. The pellet is sealed in a metal can, with one or two pins emerging from the bottom.

The dielectric material is what separates the negative and positive terminals of the device, and is responsible for the capacitance. It is made of a metal-manganese dioxide-electrolyte system, which is mixed and nicely pressed into a pellet. The dielectric material and its composition has also been especially chosen to provide a very high level of electrical stability over time.

The M39003/01-5249 series of tantalum capacitors are hermetically sealed in a metal can, which protects the device from moisture, dust, and other environmental contaminants. The seals of the metal can also prevent the capacitor from being damaged by thermal shock. The metal can also provides additional shielding from unwanted electrical noise.

Working Principles

Tantalum capacitors work on the principle that when two electrical conductors (plates) are insulated from one another by a dielectric material, electrical energy will flow between them. The dielectric material can either be a solid or a liquid, but it must be electrically non-conductive. The dielectric material acts as a barrier between the two plates, allowing the capacitor to store electrical energy.

The plates of the capacitor are connected to the positive and negative terminals of the device. When an electrical charge is applied to either of the plates, charge will accumulate on the other plate, creating a potential difference between them. This is known as capacitance.

As the potential difference increases, so does the capacitance. When the voltage at either plate reaches its maximum levels, the charger no longer flows across the plates and the capacitor is said to be \'fully charged.\' At this point, the capacitor will retain the charge and can then be discharged when needed.

Applications of the M39003/01-5249

The M39003/01-5249 series of capacitors is designed for use in a variety of applications, including power supplies, DC-DC converters, filter networks, and general purpose circuitry. The surface mount design of this device makes it ideal for use in space-restricted applications. It can also be used in high-temperature environments, due to its superior thermal characteristics.

These tantalum capacitors are well suited for use in high-end audio systems, as they can store large amounts of energy and provide excellent audio quality. The M39003/01-5249 is also commonly used in digital circuits, as it helps to reduce noise and eliminate interference.

The M39003/01-5249 series of tantalum capacitors are ideal for applications requiring high levels of electrical stability, such as communication systems, GPS navigation systems, and medical equipment.
