Aluminum - Polymer Capacitors

Aluminum - Polymer Capacitors are becoming increasingly popular with manufacturers as improved versions of aluminum electrolytic capacitors. The most popular aluminum-polymer capacitor series is the PVH-20V470MG70E-R2 series, which is particularly suitable for high current applications.

Application Field

The PVH-20V470MG70E-R2 capacitors are used mostly in power factor correction circuits, and they are especially useful in situations where the current demand varies, as they have low ESR, fast charging speeds and high peak current capabilities. These capacitors are also often used in motor drives, lighting systems and automotive applications, due to their low dissipation factor and high robustness.

Working Principle

The PVH-20V470MG70E-R2 series is based on a dry metallized aluminum foil substrate, which is coated with a high dielectric liquid polymer. This composite structure ensures a high capacitance-to-volume ratio and low inductance. Because of its construction, the PVH-20V470MG70E-R2 series is more resistant to temperature, humidity and other environmental factors than traditional electrolytic capacitors. This makes them more reliable and suitable for longer-life applications.The structure also provides superior charge and discharge characteristics compared with electrolytic capacitors. The low ESR and low ripple at high frequencies, coupled with the self-healing property of the dielectric, provide high peak operating current with minimal voltage drops and temperature rise.

Conclusion

The PVH-20V470MG70E-R2 series of aluminum-polymer capacitors are versatile and robust components that can be used in a wide range of high current applications. Their construction features provide higher reliability and reduced temperature rise, making them great for longer-term applications.
