Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) are a type of capacitors that have a greater amount of energy stored than most other capacitors due to their dielectric properties. They use an electrolyte and aluminum foil as a dielectric, so the amount of energy stored is much larger than other capacitors such as ceramic or film capacitors. They also offer more stability in varying temperatures that are higher than that of film capacitors. This makes them ideal for use in high-temperature environments or applications that require a high degree of stability.

125262U040AK1B application field and working principle

The 125262U040AK1B is an aluminum electrolytic capacitor that is primarily used in starter motors and generators for automotive and electromechanical applications. It features an 85°C maximum temperature rating, and a very low-ESR of 0.35mΩ. This makes it suitable for applications that require high-stability electrical performance and minimal power loss. It also features excellent surge and ripple-current capabilities.

The working principle of the 125262U040AK1B is similar to all other electrolytic capacitors. At its core is a pair of aluminum anodes that are separated by a dielectric material, such as an electrolyte or paper. When it is charged, it stores electrical charge between the anodes. By connecting the anodes to different electric potentials, the capacitor forms a potential difference or voltage across its terminals. This stored electrical energy can then be used when needed.

This capacitor features a low impedance, allowing it to handle high-current loads with minimal power loss. It also has excellent ripple-current handling capabilities, making it suitable for applications such as starter motors and generators. Its low profile also makes it suitable for applications where space is at a premium.

In summary, the 125262U040AK1B aluminum electrolytic capacitor is a high-quality, efficient, and reliable capacitor that is suitable for applications such as starter motors and generators. Its low-ESR and outstanding surge and ripple-current capabilities make it an ideal choice for automotive and electromechanical applications.
