Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components that store energy to provide a boost or power backup in electronic devices and circuits. They are a form of non-polarized capacitor, which means current can be applied in both directions through the device without fear of damaging it. The characteristics of aluminum electrolytic capacitors vary depending on their size, material and electrolyte.

UBT2C101MHD8 application field

The UBT2C101MHD8 is an aluminum electrolytic capacitor with a standard long life. It has an operating temperature of up to 105°C and is suitable for a variety of general-purpose applications including power supplies, audio equipment, design circuitry and applications involving switching and timer circuits. It features a voltage rating of 16 VDC and has a capacitance of 1000 microfarads.

UBT2C101MHD8 Working Principle

The UBT2C101MHD8 works on the principle of capacitive reactance. This means that when a current is applied to an electrode, the electrode experiences a voltage drop proportional to the current applied. This voltage drop is known as the capacitive reactance. The magnitude of the capacitive reactance depends on the size of the capacitor, the capacitance and the frequency of the applied AC current.

In aluminum electrolytic capacitors, the capacitive reactance is generated by the presence of a rich electrolyte between the aluminium oxide layer and the conducting foil. When a current is applied, the electric field generated by the current causes ions to move from one electrode to the other, creating an electrostatic field. As the ions move, they carry stored energy known as capacitive reactance. The greater the capacitance, the more ions can be moved, and the greater the capacitance reactance.

The UBT2C101MHD8 is an aluminum electrolytic capacitor that is best suited for applications that require long life and moderate amounts of capacitance. The device operates at 16V and features a 1000 microfarads capacitance rating. The device has an operating temperature of up to 105°C, making it suitable for applications that require high temperature capability.
