Tantalum capacitors are well-known for their advantages and are widely used in electronic products.The M39003/01-5349 is a version of tantalum capacitors that boasts excellent performance, great reliability and relatively low cost. It is widely used in various electronic products such as military and space electronics, household appliances, mobile phones, computers, and many other electronic products.

The external appearance of the M39003/01-5349 is similar to that of an aluminum electrolytic capacitor, with a cylindrical shape and two insulated leads connected to the capacitor’s terminals. However, there are some important differences. Inside the capacitor, the anode is made of a pure tantalum plate. An electrolyte-saturated porous dielectric layer is formed on the surface of the tantalum plate, and the cathode is a layer of metal oxide. This metal oxide layer is formed by the oxidation of the tantalum plate itself. This layer of metal oxide works as a dielectric medium and stores electric energy.

The working principle of the M39003/01-5349 is simple. In AC applications, a voltage is applied across the two leads of the capacitor in alternating directions. The current flow through the capacitor charges the metal oxide layer, resulting in a charge and discharge cycle. This charge and discharge process is called “capacitance”. This cycle is repeated in each half cycle of the AC signal, and the capacitor accumulates charge with each cycle. This is why the capacitor is called “electrolytic”.

In addition to AC applications, the M39003/01-5349 can also be used in DC applications, such as voltage regulation and filtering. In this application, a DC voltage is applied across the two leads and current flow is maintained as long as there is a difference in voltage across the leads. In this case, the capacitor acts as a filter, removing unwanted high-frequency signals and preventing them from reaching other components. The capacitor also absorbs any changes in the amplitude of the DC signal, thus reducing the overall level of noise.

The M39003/01-5349 is an excellent choice for applications that require good reliability, low leakage current, and a low price. It is designed to be used in electronic products requiring higher capacitance and lower leakage current than what is achievable with aluminum electrolytic capacitors. In addition, it has good performance in high frequency applications and provides excellent noise suppression in both AC and DC circuits. This makes it an ideal choice for many applications including military and space electronics, computers, mobile phones, and many other electronic products.
