Tantalum capacitors are capacitors that use tantalum metal as an anode, and can be subdivided into two categories: solid tantalum capacitors and wet tantalum capacitors. The TAP474M035DCS is a type of solid tantalum surface-mount capacitor. It is a \'wet slug tantalum capacitor\' with a very small size, and is sometimes referred to as a \'miniature tantalum\'.

The TAP474M035DCS consists of a wet tantalum slug that is hermetically sealed in a ceramic package, using a metallic leadframe. The capacitor is coated with a conformal coating to ensure electrical insulation between components. On the surface of this capacitor, there are two terminals, and a laser marked type code. Each capsule contains the desired electrolyte, and a sintered tantalum anode.

The TAP474M035DCS is available in a wide range of capacitance ratings, from 0.47 to 470ufF, and its current ratings range from 1 to 35 mA. Its voltage rating is typically 4.7V DC. Its ESR is typically below 50 ohms, and its DCL is generally below 6uA.

TAP474M035DCS is ideal for applications such as timing circuits, power-supply decoupling, and high-frequency filtering. Due to its small size, low ESR, high capacitance and low DCL, the TAP474M035DCS is suitable for both high-frequency, high-impedance applications, such as timing circuits, and low-frequency, low-impedance applications, such as decoupling and noise filtering. Its excellent environment-resistance makes it a suitable choice for use in outdoor and industrial applications.

In terms of its working principle, the TAP474M035DCS uses an electrolytic solution as an electrolyte and a barrier layer (dielectric) to store electrostatic energy. The anode is made of sintered tantalum, and the electrolyte is surrounded and sealed by a ceramic package. The anode and cathode electrodes are coated with an oxide layer, which acts as the dielectric layer.

When a potential is applied between the two electrodes, the oxide layer decomposes and stores electrostatic energy. This energy is released when the capacitor is discharged, allowing the current to flow from one electrode to the other. Once the capacitor is discharged, the oxide layer reforms and the capacitor can be recharged.

The TAP474M035DCS is a reliable and versatile capacitor, and it is well-suited for a variety of applications in both commercial and industrial settings. Its small size and high capacitance rating make it a good choice for high-frequency, high-impedance applications, and its low ESR and DCL make it a suitable choice for low-frequency, low-impedance applications. As a result, the TAP474M035DCS is the capacitor of choice for many applications across a wide range of industries.
