M39003/03-4028/HSD

Tantalum capacitors are electronic components used to provide both energy storage and voltage regulation. They are sometimes referred to as tantalum electrolytic capacitors or simply electrolytic capacitors because of the principles they use for voltage regulation. The M39003/03-4028/HSD tantalum capacitor is an example of a high-performance, general-purpose, polymer based, tantalum capacitor.

Construction and Physical Appearance

The M39003/03-4028/HSD stands for ‘high-stable-design’ and is used to denote the construction of the capacitor. It is a cylindrical capacitor composed of an inner anode and an outer cathode, with a solid tantalum pentoxide layer between them that acts as the dielectric. The anode is the positive side of the capacitor, and the cathode is the negative side. This type of capacitor has a rated voltage of 10 V and a capacitance of 10 µF. The exterior casing of the M39003/03-4028/HSD capacitor is composed of an epoxy-coated aluminum shell, with the anode and cathode terminals separated by an insulating layer.

Application Field

Tantalum capacitors are commonly used in the industrial, automotive, aerospace and military sectors. The M39003/03-4028/HSD capacitor has been specifically designed to be applied in tighter fit applications that require a size reduction over other types of capacitor. These are primarily used as decoupling and filtering capacitors in high-reliability exercises, such as in avionics, space flights and medical technology.

The M39003/03-4028/HSD capacitor is also often used in consumer electronic products due to its relatively low cost and high reliability. It is suitable for use in portable radios, telephones, calculators and digital cameras due to its low profile and high capacitance. Due to its robustness, it can also be used in automotive and military applications where harsh environments and high temperatures are common.

Working Principle

Tantalum capacitors work through the principle of electrolytic capacitance. This type of capacitance occurs when a voltage is applied to two conductors which are separated by a non-conductor, in this case tantalum pentoxide. As a result of this voltage, an electric field is generated within the capacitance, which in turn allows electrons to flow between the gas molecules within the non-conductor. This electric field creates an atom-ion cloud that stores the electrical charge.

The M39003/03-4028/HSD capacitor is built using the same basic principles as a standard electrolytic capacitor, but has a higher level of stability and reliability. For added stability and reliability, it has an epoxy coating that protects it from environmental factors such as moisture, dust and shock. Additionally, its construction allows for high levels of ripple current and operating temperature.

Conclusion

The M39003/03-4028/HSD is one of the most reliable and versatile tantalum capacitor models available. Its high-reliability construction makes it an ideal choice for space, military and medical applications, while its low cost makes it perfect for consumer applications. Additionally, its construction allows for high levels of ripple current and operating temperatures, making it a great choice for a variety of scenarios.
