Tantalum Capacitors

Tantalum capacitors are widely used in electronic components in industries such as consumer electronics, aerospace, automotive, and medical. The M39003/03-4072/TR is one of the most widely used tantalum capacitors due to its robust construction and high reliability.

Application Field

The M39003/03-4072/TR\'s application field lies mainly in the consumer electronics, aerospace, and defense fields. This type of tantalum capacitor is specifically designed for applications such as portable audio speakers, digital cameras, DVD players, and laptop computers. In the aerospace and defense fields, it is used in guidance system such as Inertial navigation systems, satellite receiver, and airborne radar systems.

Working Principle

Tantalum capacitors are similar to aluminum electrolytic capacitors, which use the same construction but with a different dielectric layer material. Tantalum capacitors are constructed using a tantalum wire as the anode, a metal oxide-forming material such as tantalum pentoxide as the dielectric layer, and a conductive organic polymer as the cathode. When the capacitor is connected to a power source, the anode becomes positively charged, while the cathode becomes negatively charged. This creates an electrostatic effect which in turn allows electric current to flow between the two electrodes.

The M39003/03-4072/TR\'s popularity stems from its superior properties such as small footprint, high temperature stability, effective terminal coating, and superior electrical characteristics. It features a capacitance range of 1µF to 22µF with a rated voltage range of 6.3V to 50V. This allows for a wide range of applications from small signal filtering to high-frequency applications. Additionally, its design makes it highly reliable, even during long-term operation, and it has a wide operation temperature range of -55 C to +125 C. This makes it an ideal choice for applications that must operate in harsh environments.
