ERLA181LIN152KA40M

Introduction

Aluminum electrolytic capacitors are mainly polarized capacitors. The aluminum electrolytic capacitor is a common type of capacitor. It is composed of three parts: a metal case (usually an aluminum can), an electrolyte, and two aluminum foils wound into a roll shape. Of these components, the double layer of aluminum foil is the most important part - it is sandwiched between the non-polar high-resistant aluminum oxide dielectric film and the electrolyte, forming the capacitor\'s basic structure. Primarily used as a buffer in electrical equipment, aluminum electrolytic capacitors are a key component in the development and application of high-grade capacitors.

Application field

ERLA181LIN152KA40M aluminum electrolytic capacitors are commonly used in energy conservation, electronic transmission equipment and electronic instrumentation. Its characteristic voltage range is 18 to 63 V.DC, and the temperature range is -40 °C ~ +85 °C. For energy-saving transformers, electrolytic capacitors are used to filter, decouple and store electrical energy from the device. In electronic transmission equipment, they filter and decouple signals, and in electronic instrumentation, these capacitors are used to maintain the resonance or capacitance of the circuit.

Working principle

The working principle of the ERLA181LIN152KA40M capacitor is similar to that of other capacitors. When the capacitor is in operation, the external energy source will apply a voltage between the two poles of the capacitor, and the positive and negative charges will be accumulated on the two electrodes due to the action of the electric field. This generates an electric field between the two plates, which can store electrical energy and maintain the circuit’s electrical characteristics. Specifically, two plates of different area and distance can be used to separate the two electrodes, and a film composed of aluminum oxide can be used as a dielectric.

In addition, since the ERLA181LIN152KA40M aluminum electrolytic capacitors are polarized capacitors, special attention should be paid to the placement of the capacitor during installation. Otherwise, the capacitor may be damaged due to reversed connection, resulting in short circuit failures, leakage currents, end-pinching posts and other problems.

Conclusion

ERLA181LIN152KA40M aluminum electrolytic capacitors are important components in the development and application of high-grade capacitors and have wide uses in energy conservation, electronic transmission equipment and electronic instrumentation. To maintain its performance and ensure its safety, attention must be paid to the correct installation and polarity of the device.
