Film Capacitors

Film capacitors are highly dependable components that are widely applied in many electrical and electronic equipment. BN074G0223K is a capacitance type of film capacitor, mainly used in the high-frequency signal filtering and harmonic filtering of various power supply circuits. It is especially suitable for high-frequency communication equipments that have the requirement of multiple rated currents, such as mobile communications base stations and wireless repeaters. It also supports a wide range of temperature and humidity, and can operate in extreme working environments.

The design of BN074G0223K is based on the construction of a mechanical multilayer stack made from high-quality flexible polyester or polypropylene films that have been coated with special dielectric materials, such as aluminum oxide. After the membranes are placed one on top of the other and their edges are wrapped together in a cylindrical form, the capacitance is then fixed inside the winding. With the dialectrics and electrodes precisely aligned, the dielectric breakdown voltage of each winding is checked and recorded.

The working principle of a film capacitor is based on its principle of electrostatic energy storage. When a voltage is applied to a capacitor, electric field lines are formed around the two electrodes, creating an electrostatic field. This in turn causes a displacement of electric charges in the dielectric material, which generate an electric field capable of storing electric energy. The amount of energy stored depends on the capacitance, which is determined by the amount of charge stored per unit area. The amount of charge stored in a capacitor is proportional to the applied voltage, and its capacitance will change depending on the type of dielectric material used.

Film capacitors are particularly advantageous when used in applications that require low loss and high DV/DT, such as power electronics and snubber circuits. Compared to equivalent electronics with and without film capacitors, those with film capacitors show a lower power loss, lower cost, lower ESR and lower temperatures. This is because film capacitors inherently have a lower ESR and are more stable when exposed to temperature-dependent breakdown effects.

Size-wise, BN074G0223K is a cylindrical, through-hole capacitor with a total length of 7.4mm. Its maximum rated voltage is U=100VAC, and its capacitance is 0.001uF to 10uF. The rated current is 15uA to 1500uA, with a tolerance range of 5% to 10%. BN074G0223K features low inductance, high stability, low ESR and high capacitance. It also meets ENEC and RoHS standards, making it the ideal choice for applications with special requirements. Therefore, it is the ideal choice for customized products and for applications in high-frequency signal filtering, harmonic filtering, and other DC and AC applications.

In conclusion, BN074G0223K is a film capacitor that is widely used in multiple industries due to its reliability and versatility. It is designed with high quality dielectric materials and its capacitance can be precisely controlled. Moreover, it has a wide range of temperature and humidity tolerance, making it suitable for use in extreme working environments. BN074G0223K is the perfect choice for applications that require high frequency, low loss, and stability.
