Film Capacitors

Film capacitors are dry-type, non-electrolytic capacitors with a composite dielectric consisting of polyester (PET), polypropylene (PP), polycarbonate (PC), or polyphenylene (PPS) film and metalization of aluminum or zinc. They are also sometimes referred to as "plastic film capacitors," as most capacitor dies are made of a more rigid plastic than films used for packaging. These flexible dielectric layers are vacuum deposited on a substrate, and sometimes applied with an adhesive backing.

BFC236647154, a film capacitor, is specially designed for applications such as automotive and audio products. Its ceramic substrate provides increased reliability and robustness, and its small size makes it a great choice for smaller products. It also has low ESR and higher ripple current capability than other film capacitors on the market.

Application Fields

BFC236647154 is suitable for power supplies, mobile phones, digital TVs, DVD players, etc. It can also be used in high-reliability applications such as computers and automotive electronics.

In power supplies, BFC236647154 can provide excellent noise suppression performance with its low ESR and low losses. It can also help to suppress surge and ripple currents. In mobile phones, BFC236647154 can help to extend battery life and reduce radiation emissions. In automotive electronics, BFC236647154 can help to protect sensitive electronic components and reduce board size.

Working Principle

Film capacitors work by creating a barrier between two conductive plates. This barrier is known as the dielectric, and is made up of several layers. The outermost layers are usually metalized to increase the capacitance and provide good electrical contact. The layers in between are made up of flexible, insulating materials such as polyester, polypropylene, polycarbonate, and polyphenylene.

When a voltage is applied to the electrodes, an electric field is created which accumulates and stores energy in the dielectric. When the voltage applied is removed, the electric field collapses, and the stored energy is released. This stored energy helps to reduce spikes and surges of current in the power supply.

In order to extract maximum performance from BFC236647154, it is important to pay attention to the quality of the PCB layout. Proper grounding, thorough filtering, and careful routing of the signal trace will all help to ensure optimal performance. In addition, it is important to ensure the operating temperature remains within specified limits. This will ensure that the capacitor maintains its performance under all conditions.
