Tantalum capacitors have many different kinds and are widely used in electronic products. M39003/01-5316 is one of the most popular tantalum capacitors. It is a standard-size radial leaded capacitor in a variety of shapes and sizes, offering excellent electrical performance, economical cost and high voltage capability. The aims of this article are to introduce the application field of M39003/01-5316 and present its working principle.

The application field of M39003/01-5316 is mainly in telecommunications, instrumentation, audio and radio frequency applications. It can be used in circuits at low to medium frequencies. As deep discharge devices they can be used as a polarized back-up supply or an energy storage device, where their ability to prevent short cycling and low zener impedance make them ideal for power supply applications. Moreover, M39003/01-5316 is used in automotive and industrial applications where long-term stability is important.

The M39003/01-5316 series employs an anode construction with a ceramic dielectric or a plastic film as the base. The anode construction may also be comprised of two metal layers, which increases the breakdown voltage. The anode is constructed by either welding or soldering the two layers together. A cathode layer is then added to the construction by welding or soldering a pre-coated wire to the anode. Capacitance and dissipation factor are then adjusted on the anode layer and on the cathode layer depending on the application requirements.

The working principle of M39003/01-5316 utilizes the displacement of positive charge when a voltage is applied to one metal layer. The positive charge on one metal layer is displaced and a negative charge is brought up to the other metal layer. The result is the concentration of electrical charge particles on one surface and the elimination of charge particles on the other surface. The area of negative and positive charges then creates an electrical field between the two metal layers, which forms the basis of capacitance. This capacitance is increased by the addition of the cathode layer. The combined capacitance of the anode and cathode layers produces a higher capacitance and a greater dielectric strength, allowing for higher current carrying capabilities.

In conclusion, the M39003/01-5316 series is a popular tantalum capacitor and is widely used in telecommunications, instrumentation, audio and radio frequency applications. Its anode construction consists of two metal layers for increased breakdown voltage, and its cathode layer is added by welding or soldering a pre-coated wire to the anode. The device works by displacing positive charge when a voltage is applied to one metal layer, and the area of negative and positive charges generates an electrical field between the two layers for capacitance.
