Tantalum Capacitors

A tantalum capacitor is an electronic component that stores electric charge and consists of two electrodes insulated by a tantalum oxide, a dielectric material. It is important to note that the capacitor is not made of pure tantalum, but of a manganese dioxide (MnO2) powder. Though these capacitors are not as common as aluminum electrolytic capacitors, they have distinct advantages over them in applications where high levels of performance are expected.

M39003/01-6007/HSD Application Field and Working Principle

M39003/01-6007/HSD is a type of tantalum capacitor, designed for high reliability operation in avionic, medical and military applications. It features a small size and low profile and conforms to the military specification MIL-PRF-39003. This capacitor was designed to combine the versatility of an electrolytic capacitor, with excellent temperature stability, long shelf life and low leakage current.

The working principle of this capacitor is based on the charging of two conductive layers with opposite polarities. The electrical connection between the two layers is a dielectric material, in this case, a tantalum oxide. The principal operating theory is the same as with any other capacitor, as when the capacitor is connected to a voltage source, the charge passes through the dielectric and accumulates on the two conductive layers.

The main difference from other components is that the dielectric used in tantalum capacitors is not a physical material, but atoms in an oxide state. This type of material features superior electrical properties like high levels of dielectric strength and low leakage currents. Additionally, tantalum capacitors possess a very stable capacitance value over a wide range of environmental conditions and temperatures.

The fact that the connectors between the two conductive layers are atoms in an oxide state makes these capacitors less prone to degradation due to external influences as compared to other types of capacitors that feature an electrolyte, a liquid or a film as dielectric.

The broad application fields of M39003/01-6007/HSD include, but are not limited to, decoupling, bypass and energy discharge, output filter, timing circuit and high temperature environments. Their high performance in these application areas make them a desirable option for engineers and designers who require reliable, high precision components.

Conclusion

The M39003/01-6007/HSD tantalum capacitors feature several advantages over other types of capacitors that make them increasingly favorable for designers such as reliability, stability, low profile and excellent temperature resistance. Together with their ease of installation and excellent performance in several application fields, these components rank high on the list of top choices for engineers and designers.
