Tantalum capacitors are an electronic component used to store electrical energy. At first glance, they look like small metal cans with two electrical contacts. However, there is more to these capacitors than meets the eye. Tantalum capacitors are constructed using a solid core of tantalum and feature a separated dielectric which isolates the two plates of the capacitor. This type of capacitor is commonly used in power supplies, audio equipment, cameras, and other electronic devices.

The model designation for these capacitors is 199D225X0035B2V1E3. This model number provides information about the capacitor’s working principles and application field. The model number includes the characteristics of the capacitor such as the maximum voltage rating, the capacitance, and the tolerances associated with the capacitor.

The model number prefix (199D) indicates the capacitor’s temperature characteristics. This model is rated for operation up to 125 degrees Celsius. The number 225 indicates the voltage rating of the capacitor. In this case, the maximum voltage is 225 volts DC. The next character, X, is a wildcard representing the fact that any value of capacitance may be used.

The four-digit number 0035 represents the capacitance value in picoFarads (pF). This capacitor has a rated capacitance of 35 pF. The following two characters, B2, indicate the capacitor\'s tolerance rating. In this case, it is a high-precision tolerance rating with +/-2 % of the rated capacitance. V1 denotes the type of capacitor, in this case a tantalum capacitor. The final two characters, E3, indicates the shelf life of the capacitor. The capacitor is approved for a shelf life of 3 years.

Tantalum capacitors are used in the same applications as aluminum electrolytic and ceramic capacitors. They offer the following advantages: high capacitance in a small package, low equivalent series resistance, good level of reliability, and excellent temperature stability.

Tantalum capacitors are an excellent choice for power supplies, audio equipment, cameras, and other electronic applications where long life, high reliability, and good temperature stability are desired.
