Aluminum electrolytic capacitors are one of the most popular and widely used capacitor categories on the market today. The SMQ160VS681M22X30T2 is a capacitor from the versatile family of aluminum electrolytic capacitors designed to provide a broad range of operating voltage rating from 16V to 681V. It is a radial leaded, metallized polyester film capacitor that has a much smaller case size compared to other capacitors. The SMQ160VS681M22X30T2 is often used in applications with high frequency, high temperature and high current requirements.

The unique design of the SMQ160VS681M22X30T2 allows it to perform well under operating temperatures between -40℃ and +85℃ and has a very long life rating of 3,000 hours. The dielectric used for this specific capacitor is a Metallized Polyester Film (MEF) that ensures the capacitor offers superior mechanical properties and excellent electrical performance.

The SMQ160VS681M22X30T2 is often used as an energy storage and ripple filtering backup in power supplies, motors and transformers, and electrical and electronic applications that require stable current and small size. It is also suitable for general purpose AC bypass and snubber applications in medium voltage class (greater than 160V DC).

The working principle of the SMQ160VS681M22X30T2 is based on the physics of electrolytic cells. It is constructed with two metal plates that are separated by a dielectric material and the plates are then immersed in an electrolytic solution.

When a voltage is applied across the capacitor the electrolyte solution begins to break down, resulting in free electrons that increase the current flow. The electrons will then travel through the electrolytic cell to the opposite plate and be stored on the surface of the plate. This builds up a static charge on the plate and the stored electrons create a potential difference between the two plates, which is the capacitance.

The combination of the dielectric material and the electrolyte solution forms an electric field which is responsible for controlling the current and storing the charge. The charge produced by the capacitor is limited by the resistance of the electrolyte solution and the capacitor’s dielectric material.

The SMQ160VS681M22X30T2 is an excellent choice for applications that require high current, small size, and extended life. It has excellent dielectric performance and can handle a wide range of operating temperatures. With a long life rating of 3,000 hours, the SMQ160VS681M22X30T2 is ideal for applications in high temperature, high frequency and high current requirements.
