Tantalum Capacitors - M39003/03-0442/HSD Application Field and Working Principle

Tantalum capacitors, also known as tantalum electrolytic capacitors, are a type of electrolytic capacitor that use tantalum as the anode material. These capacitors are cylindrical in shape consisting of two metallic plates and a dielectric coated material. They have higher capacitance than any other type of capacitor and often used in audio and digital applications. This article will explain the application field and working principle of M39003/03-0442/HSD type of tantalum capacitors.

Application Field

M39003/03-0442/HSD type of capacitors are designed to meet the MIL-PRF-39003 specification and have a range of capacitance from 180 μF to 2200 μF. They have a voltage range of 6.3 VDC to 50 VDC. These capacitors are ideal for use in avionics, home and industrial electronics, missile guidance systems, computers, robots and power supplies. They are used in a wide range of applications as they provide high reliability in extreme environmental conditions. For example, they are suitable for extreme temperatures (-55°C to +125°C), high humidity, shock, vibration and other harsh conditions.

Working Principle

M39003/03-0442/HSD type of capacitors use tantalum as the anode material. The tantalum anode is coated with a dielectric material such as nitride or oxide. The other electrode is the cathode, which is made of an aluminium sheet that is soaked in an electrolyte. When the capacitor is connected to a power source, an electric field is generated between the two electrodes and charges are drawn to the surface of the electrodes. This creates a potential difference between the two electrodes and an electric current is created as a result. The electric current in turn causes a charge transfer between the plates. This process results in the charging and discharging of the capacitor until the voltage level of the power source is reached.

Conclusion

M39003/03-0442/HSD type of tantalum capacitors are ideal for use in a range of applications from avionics to power supplies. Their high capacitance and high reliability are ideal for the most demanding applications. They are designed to meet the MIL-PRF-39003 specification, and their working principle is distilled down to a charge transfer between two electrodes driven by an electric field.
