Film capacitors, also known as plastic film capacitors, are capacitors composed of thin film dielectric materials and metallized electrodes. The BFC247990124 is a 35V, 9900µF aluminum electrolytic capacitor, utilizes a 180°C high temperature tolerant advanced film constructions and a self-healing process. It is ideal for applications where high temperature stability and reliability are essential and offers long life and high ripple current capability due to its metallized film construction.

Working Principle

Film capacitors,primarily due to their self-healing characteristic, have a longer-lasting lifespan than equivalent ceramic capacitors. This is because when a film capacitor fails, its failure typically appears as energy separation on the dielectric material rather than a distinct fracture—turning a property law into a physical law. In essence, particles of the failing dielectric are displaced, leading to an open circuit. Upon reversing polarity, the circuit current causes these displaced particles to be rejoined, restructuring the capacitor to its original form. In the long term,film capacitors are a logical choice over ceramic capacitors due to this self-healing process—even in the most demanding electrical applications.
