Tantalum Capacitors

Tantalum capacitors are types of electrolytic capacitors, which are widely used in electronic circuity. They are utilized in a wide variety of applications ranging from consumer electronics, telecommunications equipment and automotive systems, to military and aerospace applications. Among them, M39003/09-4048/HSD type tantalum capacitors offer superior performance and quality, making them ideal for use in various types of electronic circuits.

The M39003/09-4048/HSD type capacitors are constructed in a cylindrical form factor that can be easily soldered to a printed circuit board. The construction consists of a powdered tantalum core, which is anodized with a special anode paste. Two metal wires are attached to the anode paste which form the plate and the cathode of the capacitor. The plates are then wrapped with an insulating material and sealed with a non-conductive epoxy.

The capacitance of a M39003/09-4048/HSD type tantalum capacitor can range from 47 microfarads up to 1500 microfarads. The voltage ratings of these capacitors can vary from 6 volts to 25 volts. The maximum operating temperature for these capacitors is 105°C.

The performance of M39003/09-4048/HSD type tantalum capacitors is quite impressive. They are notable for their high capacitance accuracy. Moreover, they feature very low equivalent series resistance, which helps to minimize power losses in the circuit. They also offer excellent load life stability and low voltage derating. All these factors make them very suitable for use in high-reliability applications.

Working Principle

M39003/09-4048/HSD type tantalum capacitors utilize the same principle as other types of electrolytic capacitors. When an electric current is passed across the anode paste, ions travel from the electrolyte to the plate and form an electric double-layer. This double-layer acts as an insulator, which separates the two plates, thus creating a capacitor. The capacitance of the capacitor is determined by the amount of charge on the plates, which can be regulated by adjusting the voltage across the capacitor.

Tantalum capacitors also feature excellent thermal properties. This is due to the special anode paste, which contains a special heat-sensitive activator. When the temperature of the device increases, the activator causes the ions to move faster, which leads to an increased capacitance. This property makes tantalum capacitors very useful for applications that require temperature compensation.

In addition to their outstanding performance, M39003/09-4048/HSD type tantalum capacitors are also noted for their high temperature stability and reliability. They are able to operate in temperatures up to 125 degrees Celsius without any significant degradation in performance. This makes them extremely suitable for use in military and aerospace applications where reliability is of utmost importance.

Application Field

M39003/09-4048/HSD type tantalum capacitors are highly versatile, and therefore suitable for use in a broad range of applications. These include switch mode power supplies, motor drives, digital logic circuitry, telecommunication equipment, automobiles, musical instruments and various other consumer electronics products.

Because of their high capacitance accuracy, low voltage derating and load life stability, M39003/09-4048/HSD type tantalum capacitors are often used for high-reliability applications such as aerospace. They are also popular for use in battery back-up systems, as they are able to deliver power for prolonged periods of time even when the system is not operating.

In addition, these capacitors are also used in power conditioning or power factor correction applications. In these applications, the capacitance must be accurately adjusted to suit the load, and M39003/09-4048/HSD type capacitors are ideal for this purpose.

Conclusion

M39003/09-4048/HSD type tantalum capacitors are widely used in a variety of electronic applications. These capacitors feature superior performance and quality, making them suitable for use in a wide range of applications. They feature high capacitance accuracy, low equivalent series resistance, excellent load life stability and low voltage derating. Furthermore, they are noted for their superior reliability and temperature stability, making them ideal for use in high-reliability applications such as aerospace and military systems.
