Aluminum electrolytic capacitors are essential components in the electrical circuit, and the EKMS series aluminum electrolytic capacitors are widely used. The 401VSN121MP25S is a product of this series with a special application field and working principle.

General Information of EKMS401VSN121MP25S

The EKMS401VSN121MP25S is a sealed aluminum electrolytic capacitor with a capacitance range of 250 – 3500μF, rated voltage of 400V, screw terminal, and an operating temperature range from –55°C to +85°C. It is especially suitable for power supplies, SNUBBER, and other industrial equipment. The capacitor has an extremely low ESR (equivalent series resistance) and good bearing capacity, making it have a long service life and excellent reliability.

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are mainly composed of electrolyte, anode, and cathode, and have two types: polarized and non-polarized. Among them, polarized capacitors have inherent polarization capabilities and require no additional biasing. Polarized capacitors are widely used in various applications as they have a wide range of voltage, capacitance, and frequency, and are robust against polarity reversal. Non-polarized capacitors are used mainly in circuits where the polarity is unknown or not constant.

Compared with other types of capacitors, aluminum electrolytic capacitors have a much higher capacitance and can withstand much high voltages, but suffer from poor linearity characteristics as their equivalent series resistance (ESR) and dissipation factor (DF) remain relatively constant across the frequency range.

Application Field

EKMS401VSN121MP25S capacitors are ideal for a wide range of applications, from precision to commercial application, because of their low ESR and excellent reliability. Specifically, they have been used in the fields of medical and consumer electronics, automotive, and power supplies, to name a few. Their exceptional performance and durability make them suitable for even newer technologies such as LED lighting, semi-conductor loads, and high-voltage semiconductor drivers.

Working Principle

The working principle of EKMS401VSN121MP25S aluminum electrolytic capacitors is based on Faraday\'s law of electrolysis. The capacitor is composed of two electrodes, one of which is made of aluminum foil and is called the anode. The other is a paper or plastic film covered with an electrolyte, and is called the cathode. The electric field it produces is extremely strong, and when an external voltage is applied, an electric field is generated between the two electrodes, causing the electrolyte ions to move and form electric potential. This electric potential then acts as a storage medium for the electrical charge in the electrolytic capacitor.

In conclusion, EKMS401VSN121MP25S aluminum electrolytic capacitors are robust devices that are widely used for various applications. They are easy to use, reliable, and have a wide range of capacitance, voltage, and frequency options. Furthermore, they have a low ESR and good bearing capacity, making them a great choice for power supplies, SNUBBER, and other industrial equipment.
