185682K250RAA-F Datasheet/PDFFilm capacitors, also known as metalized paper capacitors, are the most common type of capacitor found in most electrical and electronic devices. They are widely used for their relatively high reliability and relatively low electrolytic leakage, as well as relatively low equivalent series resistance (ESR). The 185682K250RAA-F is a film capacitor manufactured by KEMET, a leading manufacturer of film capacitors. In this article, we will discuss the application field and working principle of the 185682K250RAA-F film capacitor.
The 185682K250RAA-F film capacitor is a polycarbonate plastic film capacitor with an extended temperature range. It has a rated voltage of 250V AC (150V DC) and a capacitance of 0.47uF (microfarads). The dielectric material used is metallized polycarbonate film, which offers excellent insulation properties. The capacitor has a vibration-resistant design and is RoHS compliant.
The primary application field of the 185682K250RAA-F film capacitor is in high voltage AC applications in the automotive and aerospace industries. It is used mainly for AC line filtering, voltage stabilization, voltage regulation and surge suppression. It is also used as a transient voltage suppressor in different types of electronic circuit boards and other circuits. The capacitor is approved for use in environments with up to 130 degrees Celsius and relative humidity ranging from 10-85%.
In terms of working principle, the capacitor stores energy between the plates in a film dielectric made from a polycarbonate film. When a voltage is applied to the capacitor plates, a positive and negative charge is built up, which creates a voltage potential difference, or electric field, between the plates. This electric field induces an electric current in a circuit connected to the capacitor, allowing it to store energy for use. The electric field strength ultimately determines the capacitance of the capacitor. The higher the electric field strength, the higher the capacitance will be.
In conclusion, the 185682K250RAA-F film capacitor is a high voltage AC film capacitor designed for use in various automotive and aerospace applications. It offers excellent insulation properties and is approved for use in environments with high temperatures and relative humidity levels. The capacitor works by storing energy between the plates in a polycarbonate film dielectric, and the electric field strength determines the capacitance of the capacitor.
