Film Capacitors

Film capacitors are unique high-performance capacitor elements that can provide a cost-effective alternative to many ceramic capacitors. They are mainly used in applications where high capacitance, high frequency stability, and high temperature stability are required.

155MWR100K Application Field and Working Principle

155MWR100K is a polypropylene film capacitor which is mainly used in various high frequency switching power supplies, such as PFC circuits, UPS, inverter, motor control, etc. This type of capacitor offers great performance under wide temperature range and wide frequency range. It also has excellent insulation properties, which make it suitable for use in higher temperature environment.

The 155MWR100K capacitor consists of two metalized polypropylene films separated by a dielectric substrate. The metalized films are also separated by an interleaved dielectric sheet. The metalized insulation materials are designed to ensure that the capacitance remains unchanged over a wide temperature range. When connected to a DC source, the capacitor acts as an energy storage device that stores electrical energy and releases it when needed.

The metalized films are the key components of the capacitor, and the dielectric materials used in their construction have an important impact on their characteristics. The metalized films have an even thickness and are designed to have short conduction paths between metal layers. This ensures a consistent capacitance even under extreme environmental temperature and frequency conditions.

The dielectric material used in the metalized films is also important. It must be chosen carefully to ensure that the dielectric material has the right electrical properties and is capable of withstanding high temperatures without degrading its properties. The dielectric materials used in the metalized films are also important in ensuring that the capacitor’s characteristics remain constant over a wide range of temperature, voltage, and frequency conditions.

The construction of the 155MWR100K capacitor also incorporates a unique heat dissipation system that is designed to ensure that the device does not overheat in applications where higher temperature conditions are encountered. This helps to ensure high reliability and long service life of the capacitor.

The 155MWR100K capacitor is designed to have very low equivalent series resistance (ESR) and inductance which makes it suitable for use in higher frequency applications, such as PFC circuits, UPS, inverter, motor control, etc. This makes it one of the best film capacitors for this type of applications.

Overall, the 155MWR100K is a high-performance capacitor element that can provide a great cost-effective alternative to many ceramic capacitors. It offers high capacitance, high frequency stability and high temperature stability in a wide range of environmental conditions and frequencies. With its unique heat dissipation system and low ESR and inductance, it is one of the most reliable film capacitors available today.
