CD4FD181JO3F application field and working principle

A capacitor is an electrical device that stores energy as electrical charge. The most commonly encountered capacitors are classed either as mica capacitors or polytetrafluoroethylene (PTFE) capacitors. The CD4FD181JO3F is an example of a PTFE capacitor.

PTFE capacitors are suited for a wide range of uses in high-voltage and extreme-temperature environments, making them particularly common in aerospace and industrial applications. The CD4FD181JO3F is designed for high-voltage electronic applications as well, with a working range of 25V to 1000V DC. It has the additional advantages of being flameproof and halogen-free. As a result, the capacitor is highly suited to a variety of commercial and industrial applications, such as in voltage regulators or audio-frequency power amplifiers.

The working principle of a PTFE capacitor is the same as that of other types of capacitors. It is made of alternating conducting and non-conducting layers. The conducting layers are formed of PTFE-coated aluminum foil and the non-conducting layers are formed of PTFE insulating tape. When a voltage is applied, the charge on the aluminum creates an electric field within the layers of the capacitor, allowing it to store energy as electrical charge.
