Introduction

Aluminum electrolytic capacitors have been widely used in many electronics gadgets such as laptops, desktops, and mobile phones. The most common feature of these capacitors is their high capacitance and extremely low leakage rate, both of which are important factors when it comes to electronic product performance. There are two main types of aluminum electrolytic capacitors, namely polar and non-polar. Polar aluminum electrolytic capacitors have both positive and negative electrodes, while non-polar aluminum electrolytic capacitors have only one electrode.

One specific type of aluminum electrolytic capacitor is the EEV-HD1V101P. This type of capacitor is made of an aluminum oxide film, which is coated with an electrolyte. The electrolyte acts as an insulator, preventing electrical charge from leaking out of the capacitor. This type of capacitor is often used in high-power applications, such as in power supplies and switch-mode power supply (SMPS) converters.

Application Field

The EEV-HD1V101P series is a high ripple current type aluminum electrolytic capacitor. This type of capacitor is specifically designed for high ripple current applications like power supplies and SMPS converters. The capacitor’s rated capacitance and voltage are 105µF (pF) and 25V respectively. It features high ripple current (100A) and low internal resistance (1mV) to ensure reliable performance.

The EEV-HD1V101P series is suitable for applications such as power supplies, SMPS converters, motor controls, and other high power applications that require high ripple current. It is also one of the most widely used aluminum electrolytic capacitors for automotive electronics due to its high ripple current. The capacitor also has low temperature rise, which makes it ideal for demanding applications.

The capacitor is available in several different sizes, from 25 to 150mm in diameter. The maximum operating temperature of the capacitor is +105°C, and it has a capacitance tolerance of ±20%. It has a typical life of 5,000 hours at rated ripple current and rated voltage. The capacitor also features a low ESR of 1mohm.

Working Principle

The EEV-HD1V101P series operates by using a combination of chemical and electrical energy to generate a charge. The aluminum oxide film acts as an insulating layer between the two electrodes of the capacitor, so that charge can’t move freely between them. When an electrical current is applied, the chemical energy of the electrolyte is used to move the charge from one electrode to the other.

This movement of charge creates an electrical field between the two electrodes. This field builds up until it reaches a certain level and causes the capacitor to reach electrical equilibrium, meaning that the amount of charge on each electrode is equal. This equilibrium is maintained even when the electrical current is removed, since the charge on either electrode is prevented from moving due to the insulating layer.

The EEV-HD1V101P capacitor achieves its high ripple current ratings due to its low internal resistance. The low resistance allows more current to flow through the electrolyte, reducing the amount of energy that is dissipated as heat. This helps to increase the capacitor’s life and ensure that it performs reliably.
