Film Capacitors

Film capacitors are a type of capacitor that uses plastic film as the dielectric as opposed to ceramic, electrolytic paper, or air. Film capacitors are designed to have low losses, improved stability of capacitance and excellent stability against environmental factors such as humidity, temperature and frequency. They are used in a wide variety of electrical and electronic devices, from computers to automotive electronics.

The most common type of film capacitor is the MMK15105J100B04L4BULK. It is a film-foil design with a self-healing property and is constructed with a polypropylene film and aluminum foil. It is rated for 100V DC and has a low dissipation factor of 0.1%. It has a capacitance of 1.05 μF, a tolerance of ±5%, and a temperature coefficient of under 100 ppm/°C.

The application field of MMK15105J100B04L4BULK capacitors is primarily in signal-handling and filtering applications. These capacitors are well suited for signal processing, signal conditioning, and filtering in wideband amplifiers, high-frequency switching power supplies, and signal conditioning circuits. They are also used in medical electronics, processors and controllers, switch mode power supplies, audio systems, and many other applications.

The working principle of a film capacitor is fairly straightforward. As current passes through the capacitor, charges build up near the conductive plates, forming an electric field between them. This field is proportional to the amount of charge stored in the capacitor. When the amount of charge stored gets to be too great, the opposite charges are attracted to each other and this forces the electrons to move through the dielectric material to balance the charges.

In the case of the MMK15105J100B04L4BULK film capacitor, the polypropylene film provides excellent dielectric properties. The polypropylene also offers excellent mechanical strength and excellent dielectric strength. The construction of this type of capacitor also allows it to be self-healing, meaning that the dielectric can repair itself if it ever becomes damaged.

In summary, film capacitors are an essential component in a wide variety of electrical and electronic applications. The most commonly used film capacitor is the MMK15105J100B04L4BULK. It has a capacitance of 1.05 μF, a temperature coefficient of under 100 ppm/°C, and a dissipation factor of 0.1%. It is primarily used in signal processing, signal conditioning, and filtering applications. Its working principle is based on charges building up andthen being forced to move through the dielectric material when the charge builds up to a certain point.
