Tantalum Capacitors: M39003/01-8059/TR Application Field and Working Principle

Tantalum capacitors (or tantalum electrolytic capacitors) are electrochemical capacitors characterized by their unique structure and extremely high capacitance. These capacitors feature an anode made of tantalum foil and an electrolyte composed of aqueous manganese dioxide (MnO2). The combination of an anode and electrolyte results in a device with a very high capacitance, which can be used in applications ranging from aerospace to smartphones.

The M39003/01-8059/TR capacitor is a type of tantalum capacitor produced by Vishay Intertechnology. The M39003/01-8059/TR is a radial lead, molded package, axial leaded, radial leaded, non-polarized capacitor. It has a capacitance range from 47µF to 1000µF with a voltage range of 10V to 50V.

These tantalum capacitors are used in a variety of applications, including power supplies, decoupling, high-speed switching, transient protection, and voltage hold circuits. They are known for their good saturation voltage, high frequency response, and low/stable impedance. The M39003/01-8059/TR spherical style has a higher capacitance per unit volume and provides superior traction and mechanical strength.

In terms of working principle, tantalum capacitors are electrochemical capacitors with an electrolyte and an anode. The anode is typically made of tantalum foil, which is formed into a "button" shape and sealed in a metalized sleeve. The electrolyte is typically an aqueous solution of manganese dioxide (MnO2) and potassium hydroxide (KOH). The combination of an anode and an electrolyte gives the piece a very high capacitance, which makes it ideal for applications like power supplies and decoupling in electronic systems.

The electrical properties of tantalum capacitors are determined by the capacitance, which is measured in microfarads (µF), and the maximum voltage rating, which is usually expressed in volts (V). Another important characteristic is the ESR (equivalent series resistance)—the resistance of the capacitor when in series with the circuit. Generally speaking, the higher the capacitance and voltage, and the lower the ESR, the better the performance of the capacitor.

In terms of safety, the M39003/01-8059/TR tantalum capacitor has an internal fuse that will open the circuit if it becomes overloaded. This ensures that the capacitor does not fail under excessive current loads. It is also important to note that the maximum voltage rating should not be exceeded or the capacitor can be permanently damaged.

The M39003/01-8059/TR tantalum capacitor has a wide range of applications due its high capacitance, low ESR, and excellent voltage saturation characteristics. It is used for DC filtering, high-speed switching, transient protection, and voltage hold circuits. It can also be found in power supplies, computer motherboards, and embedded systems. Additionally, the high reliability and long-life of these capacitors make them ideal for use in aerospace and military electronics.

In conclusion, the M39003/01-8059/TR capacitor is a type of tantalum capacitor that is popularly used in a variety of applications. Its unique structure and high capacitance make it ideal for use in DC filtering, high-speed switching, and transient protection circuits. Additionally, its low ESR and excellent voltage saturation characteristics make it ideal for use in aerospace and military electronics. Despite its advantages, it is important to remember to ensure that the maximum voltage rating is not exceeded, or the capacitor can be permanently damaged.
