Film capacitors (also known as plastic film capacitors, polyester film capacitors, plastic film & foil capacitors, PFF capacitors, dielectric film capacitors, and Mylar capacitors) are a type of capacitor. They are similar to electrolytic capacitors in that they act as a storage device for electrical energy but differ in their construction. Instead of utilizing an electrolyte solution, film capacitors are constructed with a film dielectric layer and are used in a wide variety of applications, including motors and fans, power supplies, and switching applications. The ECW-H12392RHV is one such type of film capacitor.

The ECW-H 12392RHV is a rectangular case, AC-rated film capacitor, specifically designed for AC applications. It is available in a variety of sizes, from 12 to 92mm in diameter. Additionally, it is equipped with robust radial leads and has a voltage rating of 450VAC. Its unique construction is designed to provide excellent dielectric properties, reliable performance, and superior shelf life. It also features excellent tolerance ratings, with capacitance tolerances as high as ± 5%.

The ECW-H12392RHV is primarily used in high voltage applications. Some common uses include switching power supplies, motors and fans, and high voltage capacitors for residential and commercial applications. Its radial leads make it ideal for applications requiring high current, short durations, or where space constraints necessitate a small size. Additionally, it is suitable for resonant applications, thanks to its low impedance.

In terms of its working principle, the ECW-H12392RHV utilizes a dielectric material to separate its two conductors, thus producing a capacitive element. The dielectric material used in the capacitor is usually polyester film, which is a combination of two plastic materials, polyethylene terephthalate (PET) and polyethylene terephthalamide (PETA). The combination of these two materials helps to maintain a high capacitance-to-volume ratio. This type of capacitor is particularly useful in AC applications, as it has a very low temperature coefficient, meaning that its capacitance remains relatively stable over a wide range of temperatures.

The ECW-H12392RHV film capacitor is well-suited for numerous applications. Its low leakage and low ESR makes it a good choice for medium frequency and pulse applications, such as motors, fans, lead / feedback networks, and switching power supplies. Its excellent dielectric properties and superior shelf life also make it a great choice for precision equipment and demanding applications. Regardless of the application, the ECW-H12392RHV is a great choice for your AC-rated film capacitor needs.
