Tantalum capacitors are solid-state capacitors that use a tantalum electrolytic metal as the anode surface. Tantalum capacitors are energy-storing elements with advantages of small size, light weight, high energy density, long life, and low cost. The T95D277K004HZAL model is a typical product of a series of tantalum capacitors including two major categories: chip and wet tantalum capacitors. It is specifically designed for military and aerospace, consumer electronics and other hot applications.

The T95D277K004HZAL consists of two conducting surfaces separated by dielectric material, two leads connected to each plate, and an internal electrostatic charge stored between the plates. The two conducting surfaces are typically made of tantalum and the dielectric material is usually an non-aqueous electrolyte. The leads are made of tinned copper and the electrostatic charge is usually electrolytic or tantalum electrolyte.

The T95D277K004HZAL offers a high dielectric constant and an excellent thermal resistance, thus it provides an enhanced capacitance stability in high temperature applications. It offers a wide range of capacitance, ranging from 1µF-470µF and a voltage range of 4-35V, making it an ideal choice for high frequency AC circuits such as switching power supplies, DC-DC converters, and amplifiers. Furthermore, it also features a low equivalent series resistance (ESR), high ripple current rating, and reverse voltage rating.

The working principle of the T95D277K004HZAL is based on the fact that metal surfaces have inherent electrical charge—coulomb force—that attracts opposite charges. When a positively-charged electrode is put in contact with another negatively-charged electrode, the capacitance is created. Doping the dielectric material with an electrolyte (a solution of ions) helps to optimize the capacitance and ESR. The electrical field created between the metal surfaces stores the electric energy and when a voltage is applied, current flows through the metallic surfaces.

The T95D277K004HZAL\'s application field encompasses all area where a reliable and performant capacitance is required, especially in military and aerospace, consumer electronics, and automotive electronics. It is also used in portable device such as handheld electronics, cellphones, and GPS devices. In addition, it is often used in AC circuits such as switching power supplies, DC-DC converters, and amplifier. Most of all, the T95D277K004HZAL\'s particularities make it a great choice for high temperature applications.
