Tantalum Capacitors: M39003/01-6185H Application Field and Working Principle

Tantalum capacitors are a type of electrical component that is typically found in portable electronic devices, circuit boards and other types of electronics, where they are used as storage elements for energy and signal processing. Typically manufactured from tantalum powder, tantalum capacitors are well-known for their versatility, having the capability to operate in a wide variety of temperature, high frequency, and usage methods.

M39003/01-6185H Application Field

The M39003/01-6185H series is a range of tantalum capacitors that is particularly designed for use in military and aerospace applications, providing top quality performance in extreme temperature and radiation environments. With their exceptional electrical characteristics over a wide temperature range, these capacitors are used for high-end electronics including radar, missiles, aircrafts and satellites.

Working Principle

Similar to other types of capacitors, the M39003/01-6185H series of tantalum capacitors work by storing electrical charge in an electrostatic arrangement. This occurs when energy enters the capacitor by means of electrical fields while being limited by their physical characteristics. Charging the surface of the capacitor plate causes an opposite charge to be formed on the adjacent plate, with opposite charges attracting each other and thus forming an electric field inside the capacitor.When the capacitance of a capacitors is increased, more energy is stored within the same volume. Conversely, when the capacitance is decreased, the amount of energy stored is also reduced. This phenomenon is referred to as the dielectric effect, and is generally characterized by the capacitors capacitance value.M39003/01-6185H series of capacitors employ an organic electrolyte solution which is held between the two electrodes. This electrolyte solution increases the capacitance, by improving the plates contact with one another, and also provides insulation between them. The M39003/01-6185H series of capacitors also use a tantalum powder solution which is compressed into the form of a solid. This powder increases the capacitance of the capacitor, by providing a film that has a higher dielectric constant.The M39003/01-6185H series of capacitors is also renowned for their high surface leakage resistance. This leakage resistance is due to the high number of surface connection points found in each capacitor element, providing an effective shield against electrical charge leakage. Additionally, the tantalum powder itself provides an additional barrier to the charge, reducing its leakage over time and thus prolonging the service life of the capacitor.

Conclusion

The M39003/01-6185H series of capacitors are a unique type of tantalum capacitors that have been specifically designed for use in military and aerospace applications, boasting a wide temperature operating range and high surface leakage resistance. They function by way of storing energy within a dielectric film, with the organic electrolyte and tantalum powder solutions both providing an increased capacitance value. This capacitor series is thus an ideal choice for extreme temperature and radiation applications, providing outstanding performance and service life.
