Film Capacitors

Capacitors are passive devices used to store electric charge. A capacitor has two terminals connected to parallel plates separated by an insulating material called a dielectric. Film capacitors are capacitors with one of the plates and the dielectric being layers of plastic film. Film capacitors are used in many applications due to their low cost and low \' ESL (Equivalent Series inductance) of which B32620A4223K189 is one example.

B32620A4223K189

The B32620A4223K189 is a Metallized Polypropylene Film Capacitor from the B32620 series of film capacitors. Its minimum insulation voltage rating is 420VAC and it has a capacitance tolerance of 10%. This capacitor has rated capacitance of 0.223µF, meaning it can store 0.223 microfarads of charge. It is an X1 approved capacitor and its dielectric has a temperature range of -40 to 85°C.

Application Field

The B32620A4223K189 is mostly used in power electronic equipment, such as wind turbines, solar photovoltaics, LED lighting, inverters and motor drives. It is also used in industrial applications and lighting circuits to reduce unwanted electrical noise. Additionally, it is used in many audio/video applications due to its low ESL and its excellent frequency response.

Working Principle

The working principle of the B32620A4223K189 is the same as any other capacitor. When a voltage is applied to the capacitor, an electric field is generated. This electric field causes the charged particles to move from one plate to the other, creating an electric field. Due to the insulation provided by the dielectric, the electric field is contained between the plates and electric charge builds up. The amount of charge stored by the capacitor is proportional to the applied voltage and its capacitance, meaning the B32620A4223K189 can store 0.223 microfarads of charge. This charge can then be released in small or large currents, depending on the application.

Conclusion

The B32620A4223K189 is a Metallized Polypropylene Film Capacitor from the B32620 series of film capacitors. It has a minimum insulation voltage rating of 420VAC and its capacitance tolerance is 10%. It is mostly used in power electronic equipment, such as wind turbines, solar photovoltaics, LED lighting, inverters and motor drives. Additionally, it is used in audio/video applications due to its low ESL and its excellent frequency response. The B32620A4223K189 works like any other capacitor, by storing electric charge between two plates separated by a dielectric. This charge can then be released in small or large currents, depending on the application.
