Tantalum Capacitors

Tantalum capacitors are kind of capacitor which are composed of tantalum powder, an oxide film that acts as a dielectric, manganese dioxide electrolyte that serves as the cathode and an external lead wire. They are usually small in size and consist of a ceramic or plastic housing with metal endcaps. Tantalum capacitors are widely used in numerous applications, such as timing circuits, power supplies, and communications systems.

M39003/01-5555 Application Field and Working Principle

The M39003/01-5555 is a general-purpose, high-capacitance tantalum capacitor with the folowing characteristics:

• Working Voltage: 10 VDC -100 VDC
• Capacitance Range: 10 μF - 2200 μF
• LowESR and self-healing
• Wide temperature range: -55 ?C to +125 ?C

The M39003/01 capacitors are the perfect choice for multiple applications. They can be used in DC-DC converters, DC-link systems, voltage regulator modules, power management, motor and motor control systems, and numerous other power electronic applications.

The working principle of this device is the same as other capacitors. It is made of two metal plates that are separated by an insulator (the dielectric). When the capacitor is charged, an electric field is created between the two plates, allowing current to flow. By controlling the amount of current and voltage in the capacitor, the capacitor’s value (its capacitance) can be changed.

The low ESR and self-healing capabilities of the M39003/01-5555 makes them suitable for high energy applications such as DC-DC converters, where the large capacitance and low ESR capabilities are required for improved transient response and power factor correction.

The low ESR also ensures good performance in high frequency applications, where the capacitor is required to store energy even at high frequencies. The low ESR also helps reduce common-mode noise, thus improving the EMC performance of an overall system.

The wide working temperature range of the M39003/01-5555 is also beneficial in some applications where the capacitor needs to operate over a large temperature range. This is particularly useful in automotive and avionics applications.

The M39003/01-5555 capacitors are also very reliable. They have an operating life of up to 2000h at +85°C. They also have excellent vibration resistance and shock resistance capabilities, allowing them to survive in harsh environments. In addition, the capacitor has a low failure rate over its entire lifetime.

In conclusion, the M39003/01-5555 is a general-purpose, high-capacitance tantalum capacitor with a wide range of applications. It is reliable, has low ESR and self-healing capabilities, and is suitable for numerous applications including power management, DC-DC converters, voltage regulator modules, motor control systems, and communications systems.
