Each capacitor is individually tested in order to ensure proper performance. In addition, they can operate at an operating temperature of 105 degree Celsius and are available in both radial and snap-in surface mount configurations.

Working Principle

EEV687M6R3S9MAA Aluminum Electrolytic Capacitors are constructed with two aluminum plates and a thin membrane that acts as the electrical dielectric. This dielectric is electrolytically formed as a film of aluminum oxide on the surface of the plates. This formation process not only provides a higher dielectric strength and greater temperature stability, but also creates a greater capacitance.

In operation, the capacitor acts as both a resistor and an inductor. When the input voltage is applied, the resistance due to the dielectric forms a resistance barrier in the capacitor. This prevents current from flowing and, in turn, limits the amount of charge that can enter or exit. At the same time, this resistance also acts as an inductor when the voltage changes. This inductance prevents the capacitor from reaching full charge very quickly, allowing it to hold steady charge over a long period of time.

Additionally, Aluminum Electrolytic Capacitors are self-healing in nature, meaning that they are able to self-repair any damage caused by voltage spikes or sudden increases in current. This is accomplished by creating a low-resistance path around the damaged section of the membrane, allowing current to pass through without having an effect on the capacitor’s performance.

Conclusion

The EEV687M6R3S9MAA Aluminum Electrolytic Capacitor is a reliable and long-life capacitor that is well suited for use in high-power applications such as power supplies, transmission and reception electronics, and various motor and generator circuits. It has a wide operating temperature range and excellent performance characteristics which make it ideal for many applications.

In addition, its self-repairing ability and the wide range of available configurations mean it can be used in a wide variety of applications and environments with minimal complications and maximum reliability.
