• Home appliance
• Automotive
• Electronic products
• Power supply
• PCB applications
• Motor control

The MKP385416125JII2T0 has a rated voltage of 50V and a capacitance of 16uF, and is also available in other capacitance ranges. Its excellent high-frequency characteristics and high dielectric strength make it suitable for high-temperature, high-frequency, and high-voltage environments.

Working Principle

The MKP385416125JII2T0 is a film capacitor that utilizes a polyethylene terephthalate (PET) film as its dielectric and aluminum as its electrodes. Its structure is comprised of two identical layers, each layer having one aluminum electrode and one PET film in between them. The PET film acts as an insulator between the two aluminum electrodes, allowing them to store electrical energy in the form of an electric field.

The capacitance of the MKP385416125JII2T0 is determined by the formula for capacitance of a parallel plate capacitor, which states that the capacitance is proportional to the surface area of the plates and inversely proportional to the distance between them. This means that the capacitance can be increased by increasing the surface area or reducing the distance between the plates. This can be done by either making the aluminum electrodes larger or by reducing the thickness of the PET film.

The MKP385416125JII2T0 has excellent insulation and dielectric properties, enabling it to handle high-temperature and high-frequency applications. It also features highly reliable connections with robust soldering capability, making it suitable for high-voltage applications. In addition, its extremely low ESR (equivalent series resistance) adds to its overall performance.

Conclusion

In conclusion, the MKP385416125JII2T0 is a highly versatile and reliable film capacitor that is primarily used for coupling or blocking applications in low-frequency noise. Its excellent insulation, low ESR, and high dielectric properties make it suitable for high-temperature and high-voltage environments, as well as for various other applications. With its robust soldering capability and wide capacitance range, the MKP385416125JII2T0 is ideal for a variety of applications where reliable and cost-effective performance is needed.
