Film capacitors, also called as film dielectric capacitors, are one of the most popular types of capacitor used in the electrical industry. They are used in a variety of applications ranging from radio receivers to complex digital circuits. The most common type of capacitor are polyester, polystyrene and paper capacitors. Among these, the SFD44S60K391B-F is a polypropylene (PP) film capacitor which has various advantages such as low ESR, low DF, better stability, low absorption of water and greater temperature range.The SFD44S60K391B-F is a type of high-performance capacitor which has good electrical properties and high frequency characteristics. The film capacitor is ideal for frequency selection filters, oscillators, circuit coupling, high-speed signal transmission and smoothing circuits. It is specifically designed for high reliability, superior performance and long lifetime. The feature of integrated ceramic core further enhances the stability and accuracy of capacitance.The SFD44S60K391B-F is an axial-lead, non-polarized polypropylene film capacitor with an operating voltage of up to 630V. It has a maximum operating temperature of up to 105°C. The coating features a clear and reliable avar and self-extinguishing when hot. The high-voltage capacitors offer better performances and they are especially used in AC adapters, power supplies, switching fields, relays, interference suppression and other power conditioning applications.The capacitor is constructed of metalized film winding and the contacts are encapsulated in epoxy resin. The contacts are made of gold or nickel and the bottom end is crimped which ensures tight connection and superior insulation performance. The capacitor has a variety of capacitance values which is defined by the color code.The working principle of the SFD44S60K391B-F is quite simple. When the leads of the capacitor are connected in circuit, electrons form an electric field across the capacitor dielectric. The incredible energy stored by the capacitor can also be released in the form of an electric current. In order to obtain greater capacitance, the film area should be larger. This also affects the drop in voltage across the film and larger capacitive reactance.The SFD44S60K391B-F capacitor is well known for its excellent damping characteristics and high frequency performance. It can be used for low-pass filtering of audio signals, decoupling, timing, voltage multipliers or for the tuning of AM/FM radio receivers. The film capacitors are also efficient for filtering out the ripple current which is generally created in the output of DC power supplies. Moreover, some other applications include hifi systems, inter stage isolation, noise suppression, analog signal transmission and for control circuits in dimmers.The SFD44S60K391B-F is an excellent choice for many different applications due to its long lifetime, superior performance, high stability and reliability. The capacitor is able to hold a great amount of energy and it can also quickly release it in the form of an electric current. It is also cost effective and the user would not have to worry about the capacitor getting discharged or damaged due to its high temperature range. Furthermore, the capacitors are equipped with excellent damping characteristics which are great for low-pass filtering of audio signals.
