Aluminum-polymer capacitors offer significant advantages over other types, including high volumetric efficiency, low equivalent series resistance (ESR), long life and stability in different temperatures. The 277ULR6R3MDY is one of the aluminum-polymer capacitors of the Cornell Dubilier Technologies line. It is available in a variety of surface mount and through-hole packages, with or without direct terminals. This paper will discuss the application field and working principle of the 277ULR6R3MDY aluminum-polymer capacitor.

The 277ULR6R3MDY is a low profile device with an X7R dielectric, which makes it suitable for high frequency applications with low ESR and an operating temperature range from -55°C to 125°C. As a result, it is mainly used in power conversion, signal filtering and bypass applications. In addition, its robust construction provides excellent reliability and high voltage withstanding capability, making it suitable for many harsh environments.

The 277ULR6R3MDY aluminum-polymer capacitor is composed of foil electrodes and solidified or membrane-coated aluminum electrolyte. The aluminum foil electrodes are made of high-quality electrolytic aluminum. The solidified electrolyte is composed of lattice hydrophilic colloidal particles, while the membrane-coated electrolyte is made of a polymer material. When a voltage is applied to the electrodes, the electrolyte molecules will form an electrical double layer, reducing the resistance and thus increasing the charge capacity. The thickness of the aluminum-polymer capacitor’s dielectric can be varied to create different capacitances. The thicker the dielectric, the higher the capacitance.

The 277ULR6R3MDY aluminum-polymer capacitor also offers superior leakage current characteristics, enabling it to effectively maintain the rated capacitance and low ESR over a wide temperature range. It also has excellent frequency response, enabling it to accurately control the ripple and noise across a wide frequency range. Additionally, the aluminum-polymer capacitor’s low inductance makes it suitable for high-frequency switching applications.

The 277ULR6R3MDY aluminum-polymer capacitor is a reliable and cost-effective alternative to other types of capacitors. It offers excellent electrical characteristics, robust construction and a wide operating temperature range, making it ideal for a variety of applications. Additionally, its low profile allows it to be easily mounted in locations where space is limited. As a result, the 277ULR6R3MDY aluminum-polymer capacitor is ideal for applications that require high current filtering and high frequency stability.
