Review CORNELL DUBILIER Piece Cde Axial Polyester Film Capacitor .22 And .47 Uf 400v

The Cornell Dubilier 4P22-1K 2000 CDE axial film capacitor is a high-performance capacitor designed for various applications where reliability, stability, and excellent electrical performance are essential. This particular capacitor has a capacitance value of 47 microfarads (0.047 farads), making it suitable for filtering or energy storage applications.

The voltage rating of this capacitor is 400 volts, which indicates that it can handle electric fields with a maximum voltage of 400 volts without breaking down or causing a short circuit. It's essential to ensure that the operating voltage of the circuit never exceeds the rated voltage of the capacitor to maintain its longevity and reliability.

The Cornell Dubilier 4P22-1K 2000 CDE capacitor is an axial-mounted capacitor, which means that it is designed to be mounted with its leads coming out of the side, allowing for more compact installation in limited-space applications. The "CDE" designation stands for "Cooled, Dipped, and Encapsulated," indicating that this capacitor undergoes an additional process where it is dipped in a special cooling liquid and then encapsulated in a protective coating to enhance its thermal stability and improve its resistance to moisture and other environmental factors.

The film capacitor technology used in this component provides several advantages over other types of capacitors. Film capacitors offer lower equivalent series resistance (ESR), which translates to better power handling and lower energy losses. They also have a more stable capacitance value over a wide temperature range, ensuring consistent performance under various conditions.

The Cornell Dubilier 4P22-1K 2000 CDE axial film capacitor is manufactured to meet the highest industry standards, including MIL-SPEC and RoHS compliance, ensuring its suitability for use in various industries, including military, aerospace, medical, and industrial applications. Additionally, it's important to note that capacitors should always be installed in circuits with the appropriate decoupling and filtering components to ensure optimal performance and prolong the life of the capacitor.
