Film Capacitors: R75LI28204000K Application Field and Working Principle

Film capacitors are widely used in various application scenarios due to their low leakage current, high insulation resistance, strong temperature resistance, and strong stability. Film capacitor R75LI28204000K is widely used because of its excellent properties. The article will explore the application fields and working principle of R75LI28204000K.

Application Fields

R75LI28204000K capacitors are primarily used as a filter in electronic circuits. They are widely used in electronic circuits, such as amplifiers, speakers, internal power supplies of computers, and AC adapters. They are also widely used in the performance and protection of medical equipment, security, and medical instruments. In addition, they are widely used in communication equipment, LED displays, and stage audio systems. Furthermore, they are suitable for high-end medical imaging equipment, digital instruments, instrumentation, communications, computer peripherals,test and measurement instruments, computers and other electronic equipment, and automotive electronic equipment.

Working Principle

The R75LI28204000K capacitor consists of two conductive materials, a dielectric material, and a storage medium. The capacitor works like this: when a voltage is applied between two conductive layers, a displacement current passes through the capacitor and produces an electric field in the dielectric, causing electrolyte ions to move. This motion of ions and charge separation forms an accumulation of charges, which produces an electrical field opposite to the external field, resulting in a decrease in electric field strength, thus reducing the current charge. The capacitor then acts as a filter and will absorb a certain amount of harmonics.

The R75LI28204000K capacitor also works like a resistor: it has a certain amount of resistance, and its capacitive reactance is proportional to the frequency, so when the frequency is changed, so does its reactance. At higher frequencies, its resistance increases, and it can act as an insulation. At low frequencies, its resistance decreases, and it can act as a virtual short, which can reduce unnecessary losses.

Ultimately, R75LI28204000K capacitors can protect the circuit from noise, filter out any unnecessary devices, and store energy when necessary.

Conclusion

R75LI28204000K capacitors are widely used in many electronic applications due to their low leakage current, high insulation resistance, strong temperature resistance, and strong stability. They can help in the filtering of unwanted noise, regulation of current energy, and protection of the circuit from current overloads. Through exploring their application fields and working principles, it is clear that R75LI28204000K capacitors are an essential part of any electronic device.
