Aluminum electrolytic capacitors are an important class of electronic components with wide applications, especially in some high frequency circuits. The MAL202134471E3 is an axial leaded aluminum electrolytic capacitor which is suitable for general purpose applications such as decoupling, filters, timing, and energy storage. It is available in two working voltages – 25V DC and 35V DC. To understand the application field and working Principle of this component, we need to look at the construction and features of the MAL202134471E3.

The MAL202134471E3 is constructed by winding an aluminum strip, coated with insulating material, around an internal conductive contact. On one side of the strip, a solid electrolyte paste is deposited. This gives the capacitor the proper electrical properties. To complete the structure, tin-plated connectors are fused at the ends of the winding. This allows for easy installation and secure electrical connections in any circuit.

The capacitance of the MAL202134471E3 is typically 0.47uF – 0.5uF. The capacitance range is determined by the thickness of the capacitance material and the overall dimensions. It is ideal for applications such as decoupling, filters, timing and energy storage. It features low ESR, low leakage current, wide working temperature range (−40 to +105 ℃) and high ripple current capacity, which makes it suitable for high frequency circuits.

The working principle of the MAL202134471E3 is based on the principle of electrochemical double layer capacitance. When a DC voltage is applied between the two poles, an electric double layer forms between the electrolyte and the anode. This condition induces a capacitance between the two poles which varies with the applied DC voltage. The capacitance also increases with the anode thickness, resulting in the higher capacitance values of the MAL202134471E3.

In addition, the MAL202134471E3 is designed to minimize losses due to ESR and the dielectric absorption. This is achieved by using a thin metallic film and an electrolyte paste between the capacitor plates. The combination of these factors ensures a high capacity to withstand large ripple current spikes and discharges.

The MAL202134471E3 has a wide range of applications. It is used in high frequency circuits such as DC-DC converters, switching power supplies, inverters, motor control circuits, audio power amplifiers, low noise circuits, etc. It is also used in industrial, aviation, medical, and motor-driven equipment. In terms of general purpose applications, the MAL202134471E3 is perfectly suitable for decoupling, filters, and energy storage.

Overall, the MAL202134471E3 is an efficient and reliable aluminum electrolytic capacitor with a wide range of applications. This capacitor is suitable for high frequency circuits and it has a wide working temperature range, low ESR, and high ripple current capacity. Moreover, its double layer construction ensures a high capacitance and minimal losses due to ESR and dielectric absorption. The MAL202134471E3 is an excellent choice for general purpose applications, as it is easy to install and fits most circuits.
