Aluminum-Polymer Capacitors are electronic components that are used to store electrical energy. They are one of the most common types of capacitors used in a variety of electrical and electronic applications including power supplies, audio equipment, and microprocessors.The EEF-CX0J121R is a very popular aluminum-polymer capacitor due to its high voltage capability and low impedance. It is a surface mount aluminum-polymer capacitor with a rated operating temperature range of -55°C to +160°C. This capacitor is also rad-hard and has a high frequency response.The EEF-CX0J121R is typically used for power filtering and voltage conversion applications. It provides stable voltage at any part of the system and reduces noise, ensuring the integrity of the signal. This capacitor also serves as a buffer between the DC power source and the load providing protection against overvoltage or surges.The EEF-CX0J121R has a maximum capacitance of 100µF and a maximum voltage of 16V. It has an ESR of 0.6Ω and an ESR cutoff frequency of 10KHz. The capacitor also features low ESR, high frequency response, high ripple current, and low EMI.The working principle of an aluminum-polymer capacitor is relatively simple. Metal electrodes are separated by a special polymer layer. During operation, electrical charges are stored on the metal electrodes. These charges then flow through the polymer layer, which acts as a dielectric.In contrast to traditional aluminum electrolytic capacitors, aluminum-polymer capacitors are more reliable and have a longer lifespan. The polymer electrolyte in the aluminum-polymer capacitor enables the capacitor to have better performance, such as lower ESR and higher ripple current. Thanks to its low ESR, aluminum-polymer capacitors are usually used in high frequency applications.The EEF-CX0J121R aluminum-polymer capacitor is a reliable, low-cost solution for power filtering and voltage conversion applications. Its low impedance combined with high voltage capability make it ideal for a wide range of applications.
