Film Capacitors

Film capacitors, also known as film dielectric capacitors, plastic film capacitors, film-foil capacitors, and polymer film capacitors, are a type of capacitor which uses plastic film as the dielectric, with metal foil electrodes, typically combined with paper or other material separator. Due to their ability to withstand high temperatures, stable dielectric constants and long life, they have become a widely used and commonly seen type of capacitor.

The BFC236755393 is a specific type of film capacitor that is used in a variety of applications because of its unique field and working principle. It is a small, lightweight capacitor that operates with a wide range of voltages. The high capacitance and voltage ratings, along with its low thermal constant, make the BFC236755393 ideal for a number of professional and consumer applications.

Application Fields

The BFC236755393 is typically used for power supply applications such as DC-DC converters, as well as for signal processing in audio, video, and RF circuits. It is also often used for general-purpose capacitors such as coupling, decoupling, snubber, and energy storage. Additionally, due to its low equivalent series resistance (ESR), it can be utilized in motor drives, uninterrupted power supplies (UPS), power factor correction (PFC), and equipment power supplies.

Working Principle

The BFC236755393 works based on a dielectric of polypropylene film and aluminum electrodes. The polypropylene film is sandwiched between the aluminum electrodes, forming a high-frequency capacitor with high insulation resistance and low ESR. The capacitor is also design with a voltage rating of 600V and temperature range of -40°C to 85°C. The dielectric is designed to operate at a frequency range of 78Hz to 100kHz.

The aluminum electrode is designed with multiple pore structures, which provides the BFC236755393 with flexibility to resist heat and voltage changes, while still providing good capacitance. The capacitor also has a self-healing property, as the capacitor can re-form at a voltage that is lower than the initially sourced voltage. This allows the capacitor to recover from minor destruction due to overloads or surges.

The BFC236755393 provides uniform response containing excellent frequency behaviour across a wide range of temperatures. This helps reduce ripple noise, enabling it to maintain excellent performance in high frequency applications such as RF circuits.
