Aluminum Electrolytic Capacitors and the EKMM201VSN681MQ40S

Aluminum electrolytic capacitors are electrical components characterized by their ability to store and release electrical energy. Consisting of an anode and a cathode, these type of capacitors offer high levels of capacitance within relatively small packages. They are primarily used to filter and store electricity and are often found in power supplies and amplifiers. A good example of an aluminum electrolytic capacitor is the EKMM201VSN681MQ40S.

Overview of the EKMM201VSN681MQ40S

The EKMM201VSN681MQ40S is a 420V rated, 0.68 μF rated aluminum electrolytic capacitor. It has a cathode-cathode capacitance of 0.3 μF. It measures 9.25 x 4.5mm. The capacitor is rated for a temperature range of -55 °C to +85 °C and an operating life of 2,000 hours.

The EKMM201VSN681MQ40S features a quick-connect termination type. This facilitates easy installation and removal of the component from its mounting location. The capacitor also features an overcurrent protection feature. This helps to protect the capacitors from potential damage caused by unexpected electrical surges.

Application Field and Operating Principle

Aluminum electrolytic capacitors are used in a wide range of applications. They are commonly used in audio, automotive, and industrial electronics. One of their core applications is in power supplies, where they act as filter and storage components. Additionally, aluminum electrolytic capacitors are often used in motor controllers, and audio and video equipment.

The operating principle of aluminum electrolytic capacitors is the diffusion of ions between the two electrodes. This process creates an electrostatic field that creates a barrier between the electrodes. The charge stored between the two electrodes is proportional to the product of the supplied voltage and the capacitance of the capacitor.

Aluminum electrolytic capacitors have several advantages compared to other type of capacitors. They typically have higher levels of capacitance than ceramic capacitors. Additionally, they are relatively inexpensive. Aluminum electrolytics are able to tolerate high voltages, and are highly reliable and durable.

Conclusion

The EKMM201VSN681MQ40S is an aluminum electrolytic capacitor that offers robust and reliable performance in a wide range of applications. Its quick-connect termination reduces installation time and its overcurrent protection feature protects the capacitor from damage. This makes the EKMM201VSN681MQ40S is a great choice for power supplies, motor controllers, and audio and video equipment.
