Product Introduction

Aluminium foil for electrolytic capacitor is an electronic component consisting of two conductive plates (usually aluminum foil) separated by an insulating medium. It is mainly used to store and release charges and regulate electrical energy. Capacitor aluminum foil needs to have high purity characteristics and be thin and uniform to increase capacitance and effectively transfer charge. Commonly used aluminum foil alloys include: 1050, 1060, 1100, 1235, 3003, etc.

A capacitor is a passive electronic component used to store electrical charge and release it in a circuit. The basic structure of a capacitor consists of an insulating medium between two conductors:

  1. Two conductor plates (plates): The two conductor plates of a capacitor are usually made of metal. The size and shape of these two plates affects the capacitance of the capacitor. One plate is connected to the positive terminal and the other plate is connected to the negative terminal.
  2. Insulating medium: The distance between two conductor plates is filled by an insulating medium, such as air, plastic, ceramic, or electrolyte. The purpose of the insulating medium is to prevent the charges between the two conductor plates from coming into direct contact with each other and to block the electric field.
  3. Plate connector: Two conductor plates usually connected to the circuit outside the capacitor, allowing the capacitor to be placed into the circuit. These connectors allow the functionality of the capacitor to be integrated into larger electronic systems.

Product Advantages

  • Conductivity: Aluminium foil for electrolytic capacitor is usually made of high-purity aluminum, which has good electrical conductivity and is able to transfer charge in the capacitor.
  • Lightweight: Aluminium metal has low density and light weight, and capacitor aluminum foil is even more lightweight, making it suitable for manufacturing lightweight electronic equipment and devices.
  • Plasticity: Capacitor aluminum foil has good plasticity and deformability, and can be easily formed according to the design requirements of the capacitor and adapt to complex structures.
  • Corrosion resistance: The aluminium foil for electrolytic capacitors has good corrosion resistance, can work stably in the capacitor for a long time, and is not easily affected by chemical substances.
  • Heat dissipation: Aluminium foil for electrolytic capacitor has good thermal conductivity and heat dissipation, which is helpful for the capacitor to maintain a stable temperature during operation.
  • Cost-Effectiveness: Aluminium foil for electrolytic capacitor generally has a relatively low cost compared to other metals or materials, providing cost advantages in the production of capacitors.
