Film CapacitorsCapacitors are broadly defined as electrical components that store and release energy in the form of electric charge. Film capacitors are one type of these components. Functionally, they work as a pair of conductors separated by an insulating material that allows electric charge to build up when a voltage is applied. This Dielectric material, along with the nature of wound designs, make film capacitors ideal for high frequency and high voltage applications. SFC66S15K391B-FThe SFC66S15K391B-F is a type of film capacitor designed and manufactured by Stackpole Electronics Inc. It is a radial-lead polyester film capacitor, also known as a Mylar capacitor. It features a miniature, low profile design, high-temperature coefficient of capacitance, and a wide temperature range. In addition, it is lead-free, features a ceramic termination and a stable capacitance over time and frequency. Application FieldThe SFC66S15K391B-F is designed for use in aviation, automotive, and general industrial applications. It is suited for interrupt, start-up, and high-voltage power circuits as well as HC/FM radio, medical diagnostic, and electronic test equipment. Due to its 9mm, low profile design, it can be easily incorporated into applications that require compact circuitry. Working PrincipleThe SFC66S15K391B-F is an AC/DC low profile film capacitor with ceramic termination. It uses a thin film of polyester to act as the dielectric material between two conductive metal plates. When electric voltage is applied, the capacitor functions by storing energy and releasing it as the electric current changes. In its simplest form, the capacitor is a pair of conductors separated by a dielectric and connected to each other by a small conducting element. The primary purpose of a capacitor is to store electric energy either for immediate use or for a current application, providing power to other electrical circuit components. When electric charge enters the capacitor, its stored energy depends on the ratio of the area of the dielectric material and its conductive metal plates. This is why the SFC66S15K391B-F has an extremely high temperature coefficient of capacitance. By increasing its capacitance, the device is able to store more energy and thus allow for greater power to be delivered. ConclusionThe SFC66S15K391B-F is a low profile, high temperature, and high voltage film capacitor designed for use in a variety of applications. It is a reliable and durable capacitor that provides high power and excellent performance in a wide range of temperature conditions. Thanks to its ceramic termination, it is able to maintain a stable capacitance over time and frequency, providing consistent and reliable power output.
