HVMLS112M075EK1A

Aluminum electrolytic capacitors are widely used in electronic circuits due to their swift response, high capacitance, low volts, high stability, and good frequency characteristics. The HVMLS112M075EK1A is a type of aluminum electrolytic capacitor with a rated voltage of 75V and a capacitance of 112μF. It is also known as a high ripple current capacitor as it is able to withstand high ripple currents.

Application Fields

The HVMLS112M075EK1A is commonly used in consumer electronics, such as smart TVs and computers, where high ripple currents are present. It is an ideal choice for flash memory modules, power supplies, power switching circuits, and servo control. It is also used in harsh environments where a large capacitance and swift response are required, such as in automotive systems. Furthermore, the capacitor is often used in high frequency and high efficiency switching mode power supplies.

Working Principle

The HVMLS112M075EK1A makes use of the principle of electrochemical double layer capacitors. These capacitors are constructed from a pair of electrodes placed in an electrolyte solution such as an ESR (Equivalent Series Resistance). The two electrodes act as oppositely charged plates that store electrical charge. The capacitors use a chemically active foil made from aluminum as one of the electrodes, which is why they are called aluminum electrolytic capacitors.

When a voltage is applied across the two electrodes, the action of the electrolyte solution causes a layer of positive ions to form on the aluminum foil electrodes. These ions act as a barrier and prevent further charge from entering the capacitor. When the voltage is removed, the positive ions dissipate and allow current to enter the capacitor and restore the charge.

The HVMLS112M075EK1A is able to handle large ripple currents and also ensure a quick response time. This is because of its capacity of offering very low ESR values. ESR stands for Equivalent Series Resistance and describes the resistive component of a capacitor\'s internal impedance. A low ESR value means that there is less resistance and as a result, current can pass through the capacitor quickly.
