Aluminum-Polymer CapacitorsAluminum-Polymer Capacitors are the most common type of aluminum electrolytic capacitors, which are the most commonly used capacitor type in today\'s electronics applications. Aluminum-Polymer Capacitors offer a number of key advantages over other types of capacitors due to their high capacitance per volume ratio, low ESR (Equivalent Series Resistance) value, and high reliability.The EEF-UE0K101ER is a type of aluminum-polymer capacitor specifically designed for high frequency applications with a low ESR value. This capacitor has a rated voltage of 16V, with a capacitance range of 0.47 to 5.00uF and aMaximum Operating Temperature of 105°C. The EEF-UE0K101ER has a 4-pin configuration, with the two lower pins being connected to the body and the two upper pins being connected to the electrodes.The capacitor consists of a sintered porous aluminum oxide layer (porous anode), and a high-temperature-resistant electrolyte sandwiched between two aluminum foil or mesh layers (collector and backer). The porous anode layer is highly porous, so that it can allow ion exchange between the electrolyte and conductive particles. The electrons within the particles will flow through the electrolyte to the collector, discharging at the anode. The collector will then carry the charge to the backer or the other electrode.This capacitor is designed to operate at high frequencies, current, and temperature levels and can resist high self-discharge rates, which is why it is often used in wireless communications systems and extreme environments. It also has low impedance and ESR values, making it suitable for applications such as battery charging, LED dimming, and other power-sensitive circuits. Additionally, its high capacitance/volume ratios provide a large capacitance with a small form factor, enabling it to easily fit into electronic systems with limited space.The working principle behind this capacitor is based on the charge that is stored and discharged through an electric field between the two electrodes. When a voltage is applied to the two electrodes, the ions are attracted to each electrode and an electric field is created. This electric field then creates a capacitor, which can store and release energy depending on the amount and direction of the applied voltage. As more ions flow, the capacitance increases until the capacity is filled and the capacitor is fully charged. The energy stored within the capacitor can then be released back into the circuit when needed.The EEF-UE0K101ER aluminum-polymer capacitor designed for use in high frequency applications and provides a reliable capacitance in a small form factor. It is one of the most versatile capacitor types due to its wide range of applications, strong performance, and long working lifespan. This capacitor is ideal for systems that require extreme operating temperatures, long working lifespans, and are low in power dissipation due to its combination of low ESR and high capacitance/volume. Overall, the EEF-UE0K101ER is a great choice for applications that require high-frequency performance and/or extreme operating temperatures.
