Film Capacitors

A film capacitor’s dielectric material is usually a polyester, polypropylene, polycarbonate or polyphenylene sulfide film. They tend to be characterized by high precision of the capacitance tolerance, low voltage coefficients, high insulation resistance and generally ultracompact dimensions.

High-end audio equipment often takes advantage of the superior accuracy of polypropylene capacitors, while plastic polyester and polycarbonate capacitors are usually preferred for their low cost and usually considered good enough for humble applications.

The BFC237590155 film capacitors are no exception, and allow for high precision functions due to their high-quality dielectric material and functional advances in their design. This allows for improvements in filtering and suppression performance, which makes them ideal for applications such as the following:

• DC-Link and Power Factor Correction Circuits
• Hold-up Circuits
• Commutation Circuits
• Power Supplies for instrumentation equipment

BFC237590155 film capacitors come equipped with an internal self-healing mechanism that reduces their contact time with the dielectric materials. This helps make them less likely to degrade over time and increases their reliability. In addition, they are issued with a molded-in cover to provide additional protection against dust and other contaminants. The exterior of these capacitors is constructed from fire-proof plastic material, making them compliant with safety certifications and regulations.

The working principle of the BFC237590155 is quite simple. When an electric field is applied to the capacitors, the dielectric material stores the electric field, which is then transferred from the dielectric material to the metal plates of the capacitor. This process is called dielectric absorption, and when it occurs, the capacitance of the capacitor increases, allowing for the capacitor to store more electric field in the same amount of space.

In conclusion, the BFC237590155 film capacitor is an appealing choice for a variety of applications due to its high-quality dielectric and self-healing mechanisms. They are constructed from fire-proof plastic for additional safety, and their small form factor helps them save space in electrical systems.
