Film Capacitors

Film capacitors, also known as polyester capacitors, are capacitors made of plastic dielectric films. They are multi-layer capacitors in which the dielectric is an organic film of polyester, polypropylene, polystyrene, paper or other film material. Film capacitors are characterized by their small size, low dissipation, low noise, good performance, and wide frequency range. The capacitance value depends on the dielectric, the dielectric thickness, the area of the capacitor, and the type of material used. This article focuses on the MKP1848S61550JP4B application field and working principle.

The MKP1848S61550JP4B is a type of film capacitor. It is an aluminum electrolytic capacitor with an axial lead. The MKP1848S61550JP4B has a capacitance of 18µF, a rated voltage of 50V, and a tolerance of ±20%. It operates in a temperature range of 10°C to + 85°C.

The MKP1848S61550JP4B is a general-purpose capacitor that is mainly used for power filtering, blocking, and bypassing applications. It is ideal for applications where stability and long-term reliability are required, such as LED lighting, software-controlled switches, solar energy circuits, elevator motor circuits, electric vehicle controllers, DC-DC converter modules, and various types of power transformers. Because of its excellent performance at high temperatures and low ESR, it is also suitable for use in ballasts, photovoltaic inverters, and LED lighting.

The MKP1848S61550JP4B has a low ESR (Equivalent Series Resistance). This low ESR makes it suitable for use in applications with higher current load and frequency variation. It also has a low internal resistance, which enables it to provide improved stability and long-term reliability. Moreover, the capacitor has a high insulation resistance and excellent frequency characteristics, which make it suitable for use in high-frequency interference suppression.

The working principle of the MKP1848S61550JP4B is based on the electric properties of dielectrics, which are materials used to separate electrical components in a circuit. The dielectric in this capacitor is a film of polyester, polypropylene, polystyrene, paper, or other non-conductive material. When a voltage is applied across the capacitor, an electric field is created, which causes electrons to flow across the dielectric, creating a charging current. This current creates an electric potential, or voltage, across the plates. This voltage is stored in the dielectric until the circuit is opened, at which point the capacitor will discharge.

The MKP1848S61550JP4B is widely used in power filtering, blocking, and bypassing applications. It is suitable for use in high-frequency interference suppression, as well as LED lighting and solar energy circuits. It is an ideal choice for applications that require long-term reliability, stability, and low ESR and impedance.
