SCRN220R-F

Film capacitors refer to the capacitors that use plastic films as the dielectric substrate. They are divided into metal foil,layer wound,coil-type,and envelope-type. They are highly stable, have excellent temperature characteristics, and are mainly used for pulse, high-frequency, and high-stability circuits. The SCRN220R-F is a type of film capacitor that heavily relied on in a variety of applications.

Applications

The SCRN220R-F has different applications in various fields. It can be found in AC/DC filter circuits in medical device applications, DC/DC converters, HID Display, and energy storage circuits. Its high-temperature resistance and high surge performance makes it ideal for use with switching power supplies, converters, and even solar inverters. In addition, its high insulation resistance and excellent self-healing properties are well-suited for pulse circuits.

Working Principle

The SCRN220R-F uses unique construction principles to achieve good insulation performance, chemical stability, and effective suppression of surge current. The metal foil is coated with different polymers, which are then cured to form a stable material. The electrodes are then printed on the film substrate and connected to two lead wires. In operation, the polymer film acts as an insulating barrier between the two electrodes. The two metal foils act as a plate between which an electrical charge builds. The electrical charge is created by a flow of electrons, and is stored in the form of an electrical field between the two foils.

Benefits

The SCRN220 film capacitor offers a range of benefits, such as excellent temperature and voltage resistance, high surge performance, and very low internal resistance. These factors enable the capacitor to perform in extreme environmental conditions, ensuring its durability even in presence of high thermal and mechanical stresses. Moreover, its self-healing properties and high insulation resistance makes it ideal for pulse and high-frequency circuits. This ensures the production of error-free and consistent signals.
