Tantalum capacitors are capacitors that use tantalum as an anode, and it is a type of electrolytic capacitors wherein the oxide layer serves as the dielectric. It features low leakage current, high capacitance and excellent stability. The M39003/01-7050/HSD is a case-style category of shielded axially leaded miniature tantalum capacitors. To use the M39003/01-7050/HSD capacitors, three factors must be considered: application field, insulation voltage and working principle.

The application field of the M39003/01-7050/HSD is most suitable for high-frequency, high-kw AC filter applications. It proves the strength of the M39003/01-7050/HSD capacitors in behaving as energy-storage elements of radio-frequency circuits or high-frequency switching power supplies. In addition, it can also be applied in communication systems, digital display products, and computer systems.

The insulation voltage of the M39003/01-7050/HSD is usually between 6.3V-50V. It is important to note that the applied voltage should not exceed the maximum rated voltage of the product. Operating at a voltage greater than the specified one will damage it and thus reduce its life span.

The working principle of the M39003/01-7050/HSD is rooted in electrostatic coupling. This implies that the capacitor acquires electrical charge when a potential difference is present across its terminals. When a DC voltage is applied, the dielectric material works as an insulator, hence allowing the capacitor to store the charge. As the applied DC voltage reaches the rated insulation voltage, the oxide layer that works as the dielectric will break down and the capacitor will short-circuit.

Teflon-based polyethylene and polypropylene (PP) are commonly used as the dielectric in the M39003/01-7050/HSD series because of their high stability and insulation. The dielectric can be further enhanced by adding manganese to the electrolyte. This will provide a longer reduction in impedance as well as good insulation.

The M39003/01-7050/HSD capacitors come in a variety of standard and custom-made packages as required by the customer. The SMD-type capacitors are available in standard EIA sizes. With the standard case sizes of 7.5mm, 10mm, and 12.5mm, the M39003/01-7050/HSD provides great flexibility when it comes to design.

In conclusion, the M39003/01-7050/HSD is a series of shielded axially leaded miniature tantalum capacitors that is suitable for high frequency, high kw AC filter applications. Its working principle is based on electrostatic coupling and its insulation voltage lies between 6.3V-50V. It features a variety of standard and custom-made packages to meet the engineering requirements of the customer. The use of the Teflon-based polyethylene and polypropylene as the dielectric, as well as the addition of manganese to the electrolyte, further enhances the performance and stability of the M39003/01-7050/HSD.
