Tantalum Capacitors

A tantalum capacitor, also known as a tantalum electrolytic capacitor, is a type of electrolytic capacitor today which is made of tantalum (a rare metal) and uses an organic electrolyte as the dielectric. It is vastly different from conventional electrolytic capacitors. It is often used in high-reliability applications such as aerospace, medical, automotive, and military since it’s very durable and reliable.

Tantalum capacitors, such as the M39003/01-6159, are polarized electrolytic capacitors that have a much larger capacitance per unit volume than other types of capacitors and is the component of choice for most high-density applications. They are also small in size and can provide high current and high capacitance in a fraction of the size of a typical ceramic capacitor.

M39003/01-6159 Application Field and Working Principle

The M39003/01-6159 is one of the most popular of the MIL-spec tantalum capacitors. This capacitor is ideal for applications that require a wide operating temperature range, excellent volumetric capabilities, and low leakage current and long life. It is widely used in the military, aerospace, and industrial markets, in addition to commercial applications.

The working principles for the M39003/01-6159 are quite simple. In a typical application, two metal electrodes are placed onto a dielectric material, which in this case is a thin layer of tantalum. The tantalum acts as the electrolyte, allowing the electric charge to flow between the two electrodes. This forms a capacitor, which can then be used to store energy in the form of electric charge. The capacitance is determined by the size and type of material used in the dielectric, with the M39003/01-6159 having an exceptional volumetric efficiency.

The M39003/01-6159 has low ESR, making them ideal for filtering power supplies, DC-DC converters, and switching systems. They also have a high impedance, making them ideal for high-frequency applications. The M39003/01-6159 also have a very low leakage current which allows for long life applications and minimal voltage drop over time.

The M39003/01-6159 are designed for use in applications where extended temperature, lubricant stability, and reliability are important. These capacitors have a wide operating temperature range and can withstand temperatures ranging from -55C up to +125C. In addition, they are very corrosion resistant and can easily handle the rigors of outdoor and long-term applications. They are also UL approved, providing additional assurance for their use in high-reliability applications.

The M39003/01-6159 tantalum capacitors offer excellent performance in a wide variety of high-reliability applications. With their excellent volumetric efficiency, small size, and high capacitance, they are the component of choice for many applications. Furthermore, their low ESR, leakage current, and high impedance make them a great choice for filtering power supplies, DC-DC converters, and switching systems. Finally, their UL approval and extended temperature range make them ideal for long-term and outdoor applications.
