Film capacitors, also known as plastic-film capacitors, plastic-film dielectric capacitors, film dielectric capacitors, are capacitors with a film dielectric material which is usually polyester, polypropylene, polystyrene, polyamide, polycarbonate, phenolic-formaldehyde resin, or polyester-imide. Film capacitors are widely used in applications where an electrical connection is required to conduct an electric current flow, such as electric motors, televisions, radios, computer systems, and power supplies. The SFT44T45-15K391E-F is a type of film capacitor that is especially suitable for use in harsh environments.

The SFT44T45-15K391E-F film capacitor has a special construction that offers excellent performance in various conditions and ensures operational reliability. This type of film capacitor uses a polyester film dielectric which is compressed between metallic electrodes that are bonded to the dielectric core. This construction creates a superior electrical insulation which is able to withstand high voltages, high temperatures, and a wide range of humidity conditions. It is also constructed with a flame-retardant surface for improved safety and a special coating that protects the electrolyte from moisture, oxidation, and caustic substances.

The application field and working principle of the SFT44T45-15K391E-F film capacitor are also worth mentioning. This type of film capacitor is mainly used in applications that require a reliable and high-performance component. It is suitable for signals up to 6 V, up to 15 kHz of frequency, and up to 15 mA of current. In addition, it can be used in applications that require a long service life, such as medical and industrial equipment.

The working principle of the SFT44T45-15K391E-F film capacitor involves the formation of an electric field across the dielectric material. This electric field is formed by positive and negative electrodes which are connected to an external circuit. The electric field opposes the current flow through the capacitor, thus creating an opposing voltage. This voltage, commonly referred to as capacitance, is the unit of measurement used to represent capacitance. The larger the electric field, the greater the capacitance and the greater the voltage.

The SFT44T45-15K391E-F film capacitor is suitable for use in a wide range of applications due to its superior electrical insulation, reliable performance, and long service life. Additionally, its special construction and unique features make it suitable for use in applications where high voltage and current, and/or high temperatures are expected. This type of film capacitor is an excellent choice for modern electronic devices and products due to its excellent performance and durability.
