Aluminum electrolytic capacitors, like all other types of capacitors, are a passive device that stores electrical energy in the form of an electric field and provides a barrier to current between two conducting materials (the electrodes). Aluminum electrolytic capacitors are constructed using aluminum foil, which is anodically treated in a process of electrochemical oxidation to create an oxide layer that serves as the dielectric. This is where the name “electrolytic” comes from; the electrolyte is the chemical that helps to create the oxidation reaction. The EKMH500VSN682MQ50T is an aluminum electrolytic capacitor.

The EKMH500VSN682MQ50T is designed for applications where a high temperature operating environment is encountered, such as in high frequency switching power supplies and DC-DC converters. It features a high temperature rating of 125°C, high ripple current of 10A at 130°C, low ESR of 0.07 Ohms (25°C), and high capacitance of 680uF. The EKMH500VSN682MQ50T is also characterized by its long life, which can exceed 1000 hours at a rated voltage of 220V. The device has a wide capacitance tolerance rating of ±20% at 25°C.

The working principle of the EKMH500VSN682MQ50T is based on the creation of a barrier between two conducting surfaces. When a voltage is applied across the capacitors, an electrical field is generated across its dielectric, causing a charge imbalance to be built up on either side of the capacitor. This charge imbalance produces a potential difference across the capacitor and an electric current will flow through the conducting materials. This current is hindered because the electric field created is stronger than the resistance of the charge carriers. The result is a temporary storage effect, in which the capacitor acts as a short term energy reservoir for the circuit.

The EKMH500VSN682MQ50T is an ideal choice for applications that require high frequency operation and/or high temperature tolerance. It is also suitable for use in high-frequency switching applications and DC-DC converters where the maximum ripple current is required. This capacitor has a high capacitance tolerance rating and a long life. It is suitable for use in harsh environments and harsh conditions due to the high durability of the device.
