Film capacitors,also known as plastic film capacitors,are general-purpose capacitors containing a thin plastic film such as polyethylene naphthalate (PEN) or polyester as the dielectric ("insulating layer"), combining with metalized, foil electrodes. B81123C1152M289 is a series of film capacitors, and this article will introduce its application field and working principle.
Generally, film capacitors are constructed by sandwiching the dielectric film between two metalized electrodes of the same material. Aluminum or zinc is often used as the metalizing agent, and these metalized electrodes are then covered with a protective film to maintain their integrity. The B81123C1152M289 capacitors are composed of aluminum foil and plastic film, with aluminum-zinc metalized electrodes and polyethylene naphthalate (PEN) as the dielectric. The devices are marked with their respective supply voltage, capacitance range, rated capacitance and capacitance tolerance.
The main application area of B81123C1152M289 film capacitors is in pulsed power systems. Specifically, the capacitors are often used in sinusoidal inverter applications, such as high-power supplies, UPS inverters, welders, and telecom systems. The high capacitance and high-voltage levels provided by the capacitors make them ideal for these applications as they can store large amounts of energy and deliver it rapidly when needed. The capacitors can also operate with high reliability in high-temperature and high-humidity conditions, making them suitable for many industrial applications.
The working principle of B81123C1152M289 film capacitors is based on capacitance, which is the ability of a circuit to store electrical energy in an electrostatic field. In these capacitors, the dielectric plastic film between the metalized electrodes acts as an insulating layer which creates an electric field when placed between two conducting plates. This electric field creates a stored charge which produces a voltage across the capacitor and provides energy to the circuit. This energy is then released as current flows through the capacitors when a load is connected or a voltage of opposite polarity is applied.
In summary, the B81123C1152M289 film capacitors are high-performance capacitors with polyethylene naphthalate (PEN) as the dielectric and metalized electrodes. The capacitors are used widely in pulsed power systems because of their ability to store large amounts of energy quickly and reliably. The working principle of these capacitors relies of capacitance, with an insulating plastic film between two metalized electrodes which produce an electric field when a voltage is applied.
