Film Capacitors

Film capacitors are designed to produce a single layer or multiple layers of plastic film with metal electrodes and sometimes with basic components. These capacitors usually have low loss, low leakage, high insulation, even under harsh conditions, and are non-polarized. Film capacitors are mainly used in power electronics applications, such as switching power supplies, solar energy and wind power applications. The capacitive values range from about 1 nF to 1 mF and the rated voltage is from 250 Vac to 2 kV.

B32671L1472J000 film capacitors are typically applied in medium voltage applications, ranging from 165 to 500V. The rated ripple current for the B32671L1472J000 is given in rms value and is lower than 10 A. With a capacitance value of 47uF, B32671L1472J000 offers high capacitance with low inductance. Additionally, they also have high ripple current and low ESR, allowing them to operate at higher frequencies. It is an ideal capacitor for pulse applications, such as motor control, medium voltage applications, etc.

Working Principle

The working principle of the B32671L1472J000 film capacitors is based on two primary properties: capacitance and dielectric loss angle. Capacitance is defined as the ability of a material to store electrical energy in an electric field. The higher the capacitance of the material, the more energy it can store. Dielectric loss angle is the ratio between the energy dissipated by a material in an electric field and the energy stored in the field.

In B32671L1472J000 capacitors, the capacitance of the material is created by thin layers of plastic film between two metal electrodes. The film is typically made of polypropylene, which has a relatively high dielectric constant. This allows for the ability to store large amount of charge and therefore larger capacitance. Once the voltage across the plates is exceeded, electrons tunnel through the thin film of the dielectric, creating an avalanche breakdown, which then further increases the capacitance.

The dielectric loss angle of the B32671L1472J000 capacitors is relatively low, allowing them to maintain their efficiency even when operating at higher frequencies. This makes them ideal for pulse applications, where pulsed currents with fast rise times and fall times are required. Furthermore, the low dielectric loss angle ensures that the capacitors remain leak-proof and able to handle high AC voltages without producing excessive heat.

Applications

B32671L1472J000 film capacitors are mainly used in power electronics applications. Due to their low loss, low leakage, high insulation and non-polarized characteristics, they are ideal for use in medium voltage applications, such as motor control, switching of power supplies, and solar and wind power projects. In addition, due to their low loss angle and high capacitance, they are also used in pulse applications and are suitable for high frequency switching.

In particular, B32671L1472J000 film capacitors are suitable for use in high switching frequency applications, such as power inverters, AC/DC converters, motor control systems, frequency changers, and more. They are also suitable for use in high voltagestrips, LED lighting systems, and other high voltage AC applications. Furthermore, they are also suitable for use in solar and wind power conversion systems, as well as any other applications where switching speeds are critical.
