Tantalum Capacitors – M39003/01-6345/HSD Application Field and Working Principles

Tantalum capacitors are a type of capacitor, the electronic component used in electrical/electronic circuits for storing and releasing energy, which use a combination of tantalum metal electrodes and a dielectric. Tantalum represents an ideal material for use in capacitors because of its extraordinary physical and chemical properties. This combination makes it a preferred choice when creating capacitors with large capacitance values in smaller packages.

The M39003/01-6345/HSD is a Tantalum capacitor which is a conductive polymer type of SMD capacitor in a C case style with a hermetic sealed end. In applications that require extreme shock and vibration resistant performance, this M39003/01-6345/HSD capacitors provide superior performance and quality.

Field of Application

The M39003/01-6345/HSD capacitors are used in military, aerospace, and medical applications because of their exceptional ruggedness and reliability. They are also used for power supplies, portable electronics, and automotive applications due to their small size, which allows them to be easily integrated into highly space constrained designs.

Additionally, the M39003/01-6345/HSD capacitors have superb temperature stability and low ESR, making them suitable for high-temperature applications. This feature allows them to compensate for temperature fluctuations, making them an excellent choice for more demanding applications.

Advantages of M39003/01-6345/HSD Capacitors

The M39003/01-6345/HSD capacitors offer many advantages over other capacitors, such as higher capacitance values in a very small package size, excellent stability with temperature changes, and higher reliability due to their robust construction. The C case style also makes them readily compatible with standard PCBs.

In addition, the M39003/01-6345/HSD capacitors possess an extremely long shelf life, which is often an advantage in many long-term applications. They are also capable of handling extreme environmental conditions such as temperature fluctuations, extreme shocks, vibrations, and humidity changes.

Working Principle

The M39003/01-6345/HSD capacitors use tantalum metal electrodes and a dielectric, which is usually an electrical insulator, to store electrical energy. When a voltage is applied across the capacitor terminals, a charge is stored in the capacitor’s internal plate. The dielectric material acts as an insulator, preventing current flow when the voltage is removed.

The capacitor’s capacitance is determined by the geometry of the electrodes, the size of the plate area, and the type of dielectric used. The dielectric material is chosen based on its insulation properties, which in turn determines the capacitor’s breakdown voltage and the energy it can store without breaking down.

It is important to note that, when a capacitor is charged, a reverse leakage current flows through the capacitor because the charge is attracted to the opposite polarity. This phenomenon is called “capacitive current” and is the reason why the capacitor should not be left connected to a power source for an extended period of time, as this can cause excess heat build-up and potentially damage the capacitor.

Conclusion

In conclusion, the M39003/01-6345/HSD capacitors are a reliable, space-saving choice for use in a wide range of applications thanks to their superior performance and quality. The combination of tantalum electrodes and dielectrics make them highly resistant to extreme environmental conditions, and their small size allows them to be used in space-constrained designs.
