Tantalum capacitors are a type of electrolytic capacitor that is produced from tantalum metal oxide and organic materials. They are widely used in many applications due to their small size, high capacitance, and low equivalent series resistance (ESR). The M39003/03-4036/TR is one of the most popular high-performance tantalum capacitors used in a wide range of applications.

Construction and Anatomy of M39003/03-4036/TR

The M39003/03-4036/TR is built around a conductive casing made of tantalum. The inside of the casing is filled with a paste consisting of tantalum particles in an organic solvent such as ethylene glycol or acetic acid. The electrodes of the capacitor are formed by placing the positive and negative tantalum wires into holes drilled through the inner wall of the casing. The internal electrodes are then connected to the outside terminals.

The exterior of the M39003/03-4036/TR is coated with a protective film, usually made from epoxy, to protect the capacitor from environmental and handling damage. The exterior also features an inscription on the top that identifies the capacitor and its electrical characteristics. These characteristics usually include the capacitor\'s rated voltage and capacitance.

M39003/03-4036/TR Application Fields and Working Principle

The M39003/03-4036/TR is a surface-mounted device that is typically used in high-frequency power conditioning circuits as well as in linear circuits such as DC-DC converters. Since the M39003/03-4036/TR has a very low ESR, it is ideal for filtering out high-frequency ripple currents, making it a great choice for use in switching regulators. It is also popular in medical equipment applications due to its low impedance and high capacitance.

The working principle of a tantalum capacitor is quite simple. When a voltage is applied across the terminals of the capacitor, there is an electric field created inside, which creates an electrostatic attraction between the positively charged particles of the electrolyte (the organic paste inside the capacitor) and the negatively charged particles of the tantalum casing. This attraction creates a temporary storage of charge, which is what allows the capacitor to store an electrical charge.

Advantages of the M39003/03-4036/TR

The M39003/03-4036/TR offers several key advantages over other types of capacitors. Firstly, it has extremely low ESR, which results in lower levels of electrical noise and improved efficiency. Secondly, it has a very high capacitance for its small size, which makes it an ideal choice for tight-space applications. Finally, its long-term reliability and high temperature operating range make it an ideal choice for high-voltage, high-current applications.

Conclusion

The M39003/03-4036/TR is a high performance tantalum capacitor that is perfect for high frequency power conditioning, linear DC-DC converters, and medical equipment applications. It offers high capacitance in a small form factor, as well as extremely low ESR and high temperature stability. All of these qualities make it a great choice for applications where space is limited and high reliability and performance are required.
