Tantalum capacitors, also known as tantalum electrolytic capacitors, are surface mount capacitors made from tantalum metal. They are sometimes referred to as dust caps, popcorn caps or t-caps. Tantalum capacitors are used in a wide range of electronic applications. They are particularly suitable for applications that require low ESR (equivalent series resistance), high capacitance and small sizes.

The M39003/03-0236/TR capacitor is a miniature tantalum capacitor in a hermetically sealed metal/ceramic body. It’s designed for use in high temperature, high reliability applications, such as automotive, medical and aerospace. The package size is 8.2 mm/ 13 mm and its operating temperature range is -55°C to +130°C. This model offers a case size of A, capacitance range of 10 μF to 47 μF, voltage range of 10 Vdc to 35 Vdc and up to a rated surge voltage of 50 Vdc. The M39003/03-0236/TR has a low ESR of typical 0.064 ohms, long life expectancy of up to 2000 hours at 125°C and high current leakage of less than 3 mA.

The M39003/03-0236/TR works on the principles of electrochemical capacitance, formed by two layers of electrodes that are separated by a dielectric material. When a voltage is applied across the two electrodes, a current will flow. This current charges up the electrodes, and forms an electric field that stores energy. The dielectric material allows the electric field to store charge without allowing a direct current to flow. The capacitance of the capacitor is measured in Farads, and is proportional to the amount of energy it can store.

In the M39003/03-0236/TR capacitor, the two electrodes are made of tantalum metal, which is an excellent conductor and doesn’t suffer from oxidation or corrosion. The dielectric material is a special polymer that offers excellent temperature stability and high capacitance. This combination allows the M39003/03-0236/TR to have a very low ESR, while still being able to support high voltages and currents.

The M39003/03-0236/TR is used in a variety of electronic applications, such as in satellite antenna systems, power supplies, solar cells, military communications devices, avionics, cellular phones and automotive electronics. It offers high capacitance, low ESR, and excellent temperature stability and reliability. Its small size and low profile make it ideal for use in confined areas. The long life expectancy makes it ideal for applications where replacement would be difficult or costly.
