Aluminum-Polymer CapacitorsESRH221M0EB is an aluminum–polymer capacitor that is a combination of traditional aluminum electrolytic capacitors and polymer tantalum electrolytic capacitors. Aluminum–polymer capacitors are known for their small size, high capacity, low ESR, and high heat tolerance. The ESRH221M0EB is designed to meet the most common needs of portable and small rechargeable battery applications.The ESRH221M0EB is a type of aluminum–polymer capacitor with a polymer tantalum electrolyte and an anodized aluminum/titanium (AL/Ti) foil electrode. This combination makes the capacitor resistant to several environmental factors and provides excellent performance in extreme conditions. The AL/Ti foil electrodes are also extremely resistant to vibration and shock.The ESRH221M0EB can handle voltage up to 21 volts and temperature up to 125°C. It has a capacitance range from 10µF to 330µF and an ESR rating of 0.22Ω. The capacitor is completely RoHS compliant, which means it does not contain hazardous substances and materials that can be damaging to the environment.The ESRH221M0EB is suitable for a wide range of applications, including in smartphone, tablet, and laptop batteries, industrial-grade automation, and medical devices. It is also suitable for more demanding applications such as power management in aerospace and automotive systems.The working principle of aluminum-polymer capacitors is based on the electrochemical principle. When a voltage is applied to a capacitor, the electrodes begin to exchange ions, which create a potential that stores energy in the form of an electric field. This electric field is responsible for charging the capacitor and providing the desired capacitance.The ESRH221M0EB is designed to provide high ripple current capabilities and excellent stability over time. This allows it to maintain its capacitance for an extended period of time, and also ensures that it will not degrade under high current and temperature conditions.To summarise, the ESRH221M0EB is a type of aluminum-polymer capacitor with a polymer tantalum electrolyte and an anodized aluminum/titanium (AL/Ti) foil electrode. It is designed to meet the most common needs of portable and small rechargeable battery applications, and can handle up to 21 volts and temperature of up to 125°C. It has a wide range of applications and its working principle is based on the electrochemical principle. It provides high ripple current capabilities and excellent stability over time, making it an ideal choice for many devices and applications.
