Film Capacitors

BFC237511681 application field and working principle

Film capacitors have good performance, wide application fields, long application life and other advantages in the field of electronic components.BFC237511681 is a special type of medium-thickness mammary film capacitors and belongs to a kind of pulse voltage compensation capacitors. It has two kinds of products, one is polypropylene film type C and the other is polyester film type E, which are capable of withstanding high surge current or peak current.

Application field

BFC237511681 can be used for pulse voltage compensation, snubber circuits, low-loss power lines, high-frequency flow improvement, motor start-up and Braking, pulse counter, etc. Whatever the peak current or surge current requirements are, BFC237511681 can meet the demand.

Working principle

The working principle of BFC237511681 consists of the following parts:

• Polarity: Positive and negative poles connected in series
• Structure: The capacitor is composed of two components: The core capacitance component is a film body with excellent stability under high temperature, and the protective component. The protective component can prevent the capacitor from over-voltage and over-temperature, giving it a long service life.
• Capacity: The capacity is composed of a core capacitance component and a bypass component. The core capacitance component is a high performance film body, and the bypass component is a special bypass capacitor which allows high frequency current to be bypassed around the film.

The core capacitance component is composed of a high performance film body, and the bypass component is composed of a special bypass capacitor which allows high frequency current to be bypassed around the film. When the peak current is over the designed value, the bypass component reaction is faster than the core capacitance components and will effectively reduce the current fluctuation.

In addition, the thickness of the film body of BFC237511681 also plays an important role in the process of pulse voltage compensation. The thin film can quickly absorb the high frequency current and make the voltage load flat and the inrush current can be effectively suppressed.
