KMQ400VS391M30X40T2

Aluminum Electrolytic Capacitors (AECs) are widely used in electronic circuits for the purpose of energy storage and as transient voltage suppressers. They are composed of two aluminum foil electrodes, separated by a spacer and impregnated with electrolyte. The electrodes are usually connected with the external circuit holding leads. The KMQ400VS391M30X40T2 model is one of the most common types of AECs available in the market. It is considered to be one of the most reliable solutions to address a wide range of applications in consumer electronics, industrial automation, and medical device.

The KMQ400VS391M30X40T2 is a dual-layered, non-solid aluminum electrolytic capacitor. It has a rated capacitance of 400V, and a 91MΩ impedance for the first layer and an increased impedance of 30MΩ for the second layer. This higher impedance is a result of its additional separation component and relatively lower dissipation rate. The KMQ400VS391M30X40T2 is available in two types of packaging: through-hole and surface-mount.

The working principle of an AEC is based on Faraday’s law, which states that an electric current is induced when a conductor experiences a change of potential. As the potential difference between the two electrodes, or capacitance, increases, the charge carriers (electrons and holes) move into the region of higher potential, i.e. from the negative terminal to the positive. This produces an electric field that opposes the further increase in potential. At this point, a steady-state potential is reached.

AECs boast a wide range of advantages for the consumer. For instance, they have a high ripple current rating, thereby enabling a smooth current flow without adverse affect on the performance of the circuit. Furthermore, AECs have a low equivalent series resistance (ESR), thereby minimizing distortion in audio and video applications. The self-healing nature of the electrodes ensures that AECs have a longer life span compared to other types of capacitors.

The KMQ400VS391M30X40T2 AEC is suitable for a wide range of applications. It can work well in communication systems (including RF circuits), as well as in high-voltage holding circuits and impulse current protection circuits. Additionally, the KMQ400VS391M30X40T2 is also suitable for various automotive applications, such as ECU systems, entertainment systems, and power steering assist systems.

In conclusion, the KMQ400VS391M30X40T2 AEC is a reliable, long-lasting solution for many applications in consumer electronics, industrial automation, and medical device. Its dual-layer design, high ripple current rating, low ESR, and self-healing nature offer numerous advantages.
