Film Capacitors

The BFC237520271 series of film capacitors include an extensive range of non-inductive, polypropylene film capacitors with high-temperature low-loss capabilities. These capacitors are designed for use in a variety of applications, ranging from hybrid-integrated circuits to energy-storage Coupling and bypassing purposes. BFC237520271 capacitors offer advantages in a range of applications, including:

Application Field

• High frequency AC power suppression
• Mains voltage filter circuits
• Low and medium frequency AC power line signal filters
• FM broadcast and television signal filters
• Offline power supplies
• High-voltage and high-frequency industrial applications

Working Principle

BFC237520271 film capacitors use a polypropylene dielectric medium encased in a metal film capacitor body, which is designed to provide a high degree of insulation against surge voltages and current. The polypropylene dielectric gives the BFC237520271 film capacitors a higher than average capacitance over the frequency range, making them suitable for use in high frequency AC power line filtering and bypassing applications. The capacitors also offer excellent dielectric absorption and low dielectric losses, allowing for a higher capacitance stability over a range of temperatures. Furthermore, because of the construction process, BFC237520271 film capacitors have an extremely low leakage current, which makes them ideal for use in coupling or bypassing applications.

The BFC237520271 film capacitors are also highly reliable and durable, withstanding a wide range of temperatures. This makes them suitable for use in many industrial applications, such as offline power supplies, AC power line filtering, and bypassing applications. The capacitors also feature a low maximum input voltage, making them perfect for use in applications where a very low voltage rating is required. The low voltage rating also ensures that the capacitor cannot become damaged by an accidental or intentional surge in voltage.

In order to achieve the optimal performance from the BFC237520271 film capacitors, various characteristics must be taken into consideration, such as voltage, capacitance, frequency, temperature and the rate of temperature change. Each of these characteristics can have an effect on the optimal performance and reliability of the capacitor and must be carefully taken into account for proper application.
