Among all the aluminum electrolytic capacitors, the EDH107M025S9HAA capacitors from Panasonic are remarkable for their performance characteristics and long life.

Application Field of EDH107M025S9HAA Capacitors

EDH107M025S9HAA capacitors are miniature aluminum electrolytic capacitors in a radial type sealed construction. The temperature range of the capacitors is -40 to 125 degree Celsius, with 10-year life span. With their high rated voltage of 25Vdc and a capacitance of 47uF, EDH107M025S9HAA capacitors are widely used in digital fields such as CNC machine tools, domestic appliances and consumer electronic products, or industrial automation system.

For CNC machines, the EDH107M025S9HAA capacitors can be used as a motor start components, providing a reliable supply for the power-on conversion, as their excellent ripple current-carrying capacity, good pulse load characteristics, and long life make them more suitable for motor control applications. For consumer electronic products, the EDH107M025S9HAA capacitors are used for stable power supply and high-precision signal processing, since they are characterized by very low equivalent series resistance (ESR).

Working Principle of EDH107M025S9HAA Capacitors

EDH107M025S9HAA capacitors are constructed with an electrolytic system, where two foils in an aluminum case form one pole of the capacitor, while a separator soaked in an electrolyte creates the other pole. Its working principle can be represented in the following simplified model. Normally, a certain potential difference exists between the two capacitor poles. When an AC voltage is applied across the capacitor, the high-frequency current will force electrons to cross the plate, forming a layer of electric charge on both sides of the starling foil; this results in a decrease in the capacitance.

However, in the EDH107M025S9HAA capacitors, the polarized electrolyte is enhanced by additional features designed to improve the ripple current capacity of the capacitors and increase their stability against AC power supply bias. Additionally, the addition of a drying agent in the capacitor ensures the stability of the capacitors in high humidity environment.

Conclusion

EDH107M025S9HAA capacitors is an ideal choice for many applications due to its miniature structure, good performance characteristics, and long life. The capacitors can be broadly used in CNC machine tools, domestic appliance, consumer electronic and industrial automation system due to its high rated voltage, excellent ripple current-carrying capacity, good pulse load characteristics, low ESR, and high temperature resistance.
