Film capacitors, also known as plastic film capacitors, are electronic components used to store electric charge and temporarily hold electric current. They are primarily used as smoothing components in power supplies and amplifiers, as well as for decoupling and filtering.

The 473PPB102K is a classic example of a film capacitor. It offers a small size and relatively low ESR (Equivalent Series Resistance) due to its slender electrodes, making it an ideal choice for many high-frequency applications.

In terms of applications, the 473PPB102K is often used in high-frequency noise-canceling and timing circuits, American microphone amplifiers, saw filters, and decoupling networks. It is also suitable for use as a high-voltage capacitor in many sensitive circuit applications.

The 473PPB102K works using a dielectric material to store a certain amount of electrical energy. This is why it is referred to as a "film capacitor". The material used in the construction of the 473PPB102K is polystyrene (PS), a type of extruded polyethylene. This material has a dielectric constant that is superior to other polymeric materials, making it well suited for high-frequency applications and allowing for a high capacitance value in a small package.

The electrodes of the 473PPB102K are fabricated using layers of tin-plated copper foil, with a standard lead frame construction. The layers of copper foil are plated first with a nickel alloy and then with a tin alloy in order to provide good electrical contact and corrosion resistance. This ensures that the capacitor has a long life and is suitable for use in many environmental conditions.

The 473PPB102K is an especially stable capacitor with excellent high-frequency characteristics and a low ESR value. It is also resistant to vibration and shock, making it a preferred choice for applications such as audio and radio frequency circuits. It can also be used as a power supply bypass capacitor in signal distortion and filtering circuits, as it has a low ESL (Equivalent Series Inductance) and low current leakage.

The 473PPB102K is one of the most versatile film capacitors available. It is capable of performing a wide variety of electrical tasks, making it an excellent choice for a wide range of applications. Whether you need to filter, smooth, oscillate, or simply store charge, the 473PPB102K is a perfect choice.
