MALREKA05PB315F00K

Aluminum electrolytic capacitors are widely used in various fields. The MALREKA05PB315F00K series is no exception, so what kind of application field and working principle does it belong to? This article will explain these aspects in detail.

Application Field

MALREKA05PB315F00K series aluminum electrolytic capacitors are mainly used in power line noise filters. Power line noise filters are electronic components that attenuate noise in the power line. The MALREKA05PB315F00K series has two main types: shielded and unshielded. The shielded filter is suitable for use in EMIs, which can effectively reduce the radiation of low-frequency noise to the environment. The unshielded filter is suitable for use in digital line channels, which can effectively reduce the impact of noise on digital circuits.

Working Principle

The working principle of aluminum electrolytic capacitors is mainly related to the electrolytic anode solution and the electrolyte solution. Since there are two layers of positive and negative ions in the electrolyte solution, an electric field will be generated in the electrolyte by the electric field of the anode solution, which causes the anode to absorb the ions from the electrolyte and form an oxide film over time. As a result, a capacitor between the anode and the cathode will be formed, and the current can be blocked. With the continued consumption of ions in the electrolyte, the oxide film will continue to thicken, and the capacitance value of the aluminum electrolytic capacitors will decrease gradually until it fails.

Conclusion

The MALREKA05PB315F00K series belongs to aluminum electrolytic capacitors, mainly used in power line noise filters. Its working principle is based on the electric field generated by the electrolytic anode solution and the electrolyte solution, resulting in the formation of oxide films on the anode and the cathode and the formation of a capacitor.
