Tantalum Capacitors – M39006/22-0320 Application Field and Working Principle

Tantalum capacitors are among the most integrated components in electronics, communications, or automotive applications. In comparison to other electrolytic capacitors, tantalum capacitors usually have higher capacitance and energy per volume. The M39006/22-0320 is a small-sized surface-mount tantalum capacitor for application fields, including space flight, aircraft navigation, and various medical applications that require more reliable solutions, improved ripple current, higher capacitance, or other special kinds of performance.

Capacitance and Voltage

The M39006/22-0320 series is a polarized capacitor with a rated capacitance of between 0.1μF and 1μF and a rated voltage of at least 6V. It is constructed of a tantalum anode and an electrolyte-containing layer that acts as the cathode. This capacitor is known for its extremely stable behavior in terms of temperature and voltage applications, which are usually encountered.

Construction

The construction of the M39006/22-0320 capacitor includes a tantalum anode that is in contact with a manganese dioxide material and sealed into the anode with epoxy resin. The anode and the cathode, which is typically an electrolytic material, are separated by a ceramic tube. The capacitor is then sealed with a positive and negative terminal. This is achieved by using a wire bond connection, which is then coated in an epoxy resin.

Working Principle

The working principle of the M39006/22-0320 tantalum capacitor is based on the Faraday effect, which states that the current through a conductive material is proportional to the electric field through the material. When a voltage is applied across the capacitor, a current is created through the electrolytic material which is then stored as electrostatic energy, which is proportional to the square of the applied voltage. This creates a flux which represents the stored energy. The capacitor is able to discharge this energy rapidly, as the flux reduces, thereby allowing the electric current to flow out of the capacitor. As the electric field decreases, the current decreases, and the capacitor eventually returns to its idle state.

Characteristics

The M39006/22-0320 is a high temperature component with a maximum operating temperature of 125°C, a maximum surge current of 1000mA, and a rated life of over 1000 hours. It is moisture-resistant and has the advantages of low ESL and ESR, and a very stable capacitance over a wide temperature range. The capacitor has a low leakage rate and a high capacitance retention, ensuring a longer life.

Applications

The M39006/22-0320 is a commonly used component for high reliability applications due to its reliable performance. It is used in automotive solutions, such as starter motors and electronic fuel injection systems, and in industrial solutions, such as in solar panels and DC-DC converters. It is also used in communications and audio systems, medical equipment, communications networks, and military applications.

Conclusion

The M39006/22-0320 is a small surface-mount tantalum capacitor with stable behavior in terms of temperature and voltage applications, low ESL and ESR, and a very stable capacitance over a wide temperature range. Its primary applications are in automotive and industrial solutions and in high reliability applications, such as solar panels, DC-DC converters, starter motors, and military and medical systems. This versatile capacitor is the perfect solution for many different applications and provides reliable performance for extended periods of time.
