In the electrical engineering sector, they are used inpower supplies, electric motors, circuit boards and printed circuit boards.

Working Principle

The working principle of the BFC238330683 film capacitor is based on electrical breakdown, which occurs when a dielectric of a certain thickness and voltage are applied between two metal electrodes. The breakdown is caused by the electrons in the conductor being attracted by the electric field of the electrodes, thereby creating an electric current. When electrons flow in the electric field, a charge builds up until it is strong enough to cause an electrical breakdown in the dielectric material, resulting in a sudden release of the electrical current. This phenomenon is known as dielectric breakdown.

Once the breakdown occurs, the energy released from the breakdown will cause a short-circuit in the film capacitor. This short-circuit reduces the capacitance of the film capacitor, which is dependent on the breakdown voltage. The capacitance will then start to increase again after the breakdown is stopped. Additionally, the capacitance of the film capacitor is also affected by the thickness of the dielectric and the applied voltage. If a higher voltage is applied, the breakdown voltage is greater and the dielectric thickness must be adjusted accordingly.

In conclusion, the BFC238330683 film capacitor has a wide range of applications in the automotive, medical, and electrical engineering sectors. It has an unique working principle based on electrical breakdown which allows it to provide stable voltage and temperature conditions. The capacitance of the film capacitor can be adjusted by controlling the applied voltage and the thickness of the dielectric.
