Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of electrochemical capacitor with an anode of aluminum foil and a thin dielectric layer of anodic oxide. It has some of the highest capacitance and energy density available in an electrolytic capacitors. It is also one of the highest precision and costs less in comparison with other capacitors.

The ESMH451VNN101MQ30T is an aluminum electrolytic capacitor. Its applications include motor drive circuits, DC-DC converters, DC/AC inverters, welding machines, audio power amplifiers, uninterruptible power supplies and communication power modules. It is designed for high temperature applications with a working temperature of up to +105°C.

This capacitor has two terminals, the cathode and anode. The cathode connects to the positive terminal of the power supply while the anode connects to the negative terminal. Between the two terminals is the electrolyte which consists of an oxide oxide film, allowing charges to move freely from the anode to the cathode. When an electric current is applied, an electrochemical reaction takes place between the anode and electrolyte creating a potential difference across the pair. This voltage is what allows the capacitor to store and release energy.

The ESMH451VNN101MQ30T has a capacitance of 450μF, with a breakdown voltage of 100Vdc and an ac working voltage of 50Vac. It is capable of up to 1,200 hours stability at full temperature range. This makes it ideal for applications such as solar energy storage, uninterruptible power sources and motor control. Its ripple current carrying capacity is also high, with up to 200mArms for 1,000 hours operation at full temperature range.

In conclusion, the ESMH451VNN101MQ30T is a high performing aluminum electrolytic capacitor perfect for applications in harsh environment. It has a high capacitance, ripple current carrying capacity and stability making it reliable for high temperature applications.
