Tantalum capacitors is a type of capacitors containing tantalum metal powder as the anode material. A common Tantalum capacitors is the M39003/01-6366/TR.

Application field

Tantalum capacitors is mainly used in the fields of computer systems, communication bases, sound equipments, TVs, security systems and aerospace fields, etc. The M39003/01-6366/TR is suitable for applications requiring large capacitance values in limited spaces. The capacitors CV (DC working Voltage) range from 16VDC to 50VDC. The capacitance value range from 1uF to 22uF while the ESR is from 0.005 ohms to 0.07 ohms. It is also ideal for waveform damping.

Working Principle

The M39003/01-6366/TR uses tantalum foil as electrodes and is filled with a tantalum oxide dielectric layer. When there is a voltage between the two terminals, the capacitor is able to store charge in a form of electrostatic potential energy. The dielectric material has a property that determines the amount of energy that can be stored, which is called the capacitance (C). The amount of energy stored in the device follows:

E = 1/2CV²

The equivalent series resistance (ESR) of the capacitor also affects the device dynamics. ESR determines the losses due to internal resistance and is a function of its construction. The total losses (in watts) of the capacitor can be determined as follows:

Losses = I²R – V²/R

where, I is the current through the capacitor and V is the voltage.

The ESR and capacitance values of the M39003/01-6366/TR are optimized to minimize the losses associated with the device. It possess an extremely low ESR, much lower than electrolyte based capacitors.Designers who look for quality and reliability prefer choosing M39003/01-6366/TR.
