EDH477M010S9PAA

Aluminum electrolytic capacitors are a type of nondissipative electrochemical capacitor with an electrolyte and two electrodes, usually called the anode and the cathode. The two components are separated by an ion-permeable membrane, also known as the electrolyte. Aluminum electrolytic capacitors are primarily used in applications which require storing energy or filtering signal in power electronic devices or circuits. They are ideal for a wide range of high-power and high-temperature applications such as welding and motor drives. Aluminum electrolytic capacitors are also widely used in consumer electronics, industrial, automotive, medical, and military applications.

The EDH477M010S9PAA is an aluminum electrolytic capacitor designed for high reliability, highly stable performance, and long life in high-temperature and high current applications. The capacitor has an operating temperature range of -55°C to +105°C and a rated voltage of 10 Vdc. It is a surface-mount device with a capacitance of 477 µF and ESR of 0.012 ohms. It also has a ripple current rating of 3 A (RMS) and a life expectancy of 1,500 hours at 105°C.

The EDH477M010S9PAA is unique in that it is self-healing, meaning it can withstand up to 2.5 times its rated voltage with no damage. This makes it suitable for use in high-voltage applications, where traditional capacitors may be unable to handle the increased voltage without sustaining damage. Additionally, the capacitor has a very low impedance, making it ideal for use in multiple signal filtering applications. This low impedance is also beneficial in switching power supplies, as it minimizes EMI interference and reduces power loss in the system.

The EDH477M010S9PAA also has a low ESR, which ensures that the capacitor is able to reliably store energy and filter high-frequency signals. This capability also makes it ideal for use in applications such as voltage regulation, over-voltage protection, and spike suppression. Additionally, it can be used in DC-DC converters, switching mode power supplies, and peak current mode control systems where it will provide high efficiency and good ripple rejection.

To ensure that the EDH477M010S9PAA will perform reliably in its application, the capacitor should be mounted on a flat, stable surface. It should also be connected to the ground to ensure adequate protection from electrical noise and vibration. The capacitor should be firmly fixed to the PC board or other mounting surface, otherwise it may vibrate and become loose over time. Additionally, the capacitor should not be exposed to extreme temperatures, as this could reduce its performance and life expectancy.

In summary, the EDH477M010S9PAA is an aluminum electrolytic capacitor designed for use in high-temperature and high-current applications. Its self-healing capabilities and low ESR make it ideal for use in voltage regulation, peak current mode control, and signal filtering applications. Care should be taken to ensure the capacitor is properly mounted and connected to the ground to ensure proper operation.
