Film Capacitors

Film capacitors, also referred to as Plastic Film or Polyester Film capacitors, are non-polarized capacitors made of thin dielectric plastic films with long metal or conductive elements deposited on each side. They are among the most popular types of capacitors used in electronic applications. Due to their construction and dielectric properties, they are particularly suitable in AC applications as they are able to retain their capacitance at high frequencies for use in resonant circuits.

The MKP386M515085JT6 is a specific type of film capacitor manufactured by the Kemet Corporation. It is rated at 400 volt DC with a 5mm lead spacing and a +/-12% capacitance tolerance. The MKP386M515085JT6 was designed as an ideal replacement for low value aluminum electrolytic capacitors in high frequency applications.

Application Field

The MKP386M515085JT6 is commonly used in high frequency applications such as RF circuits, audio amplifiers, digital circuits, and magnetic field shielding. Its superior self-healing property allows it to effectively protect against overvoltage transients. Due to its high capacitance per unit volume, good stability and high ripple current handling capability, it is ideal for power supply filters, lighting ballasts, switch mode power supply (SMPS) and telecom circuits.

Working Principle

The MKP386M515085JT6 is a non-polarized polyester film capacitor. When the applied voltage is increased, a corresponding electric field is generated in the dielectric material between the conductive layers. This electric field causes an increase in the electron concentration. The electrons are attracted to the positive plate and the electric force between them increases in strength. This change in electric field causes the capacitance of the capacitor to change. The MKP386M515085JT6 is an ideal choice for use in AC applications as its capacitance is stable at high frequencies which allows for reliable performance of circuits with tight tolerance limits.

Additionally, the MKP386M515085JT6 also features an exceptionally low dissipation factor of 0.00022. This ensures maximum power transfer by reducing the capacitors parasitic losses. The MKP386M515085JT6 also has very low ESR (Equivalent Series Resistance) which helps maintain an ideal working temperature in circuit applications.

Due to the high dielectric strength of the MKP386M515085JT6, it is extremely resistant to breakdown. This makes them ideal for use in high voltage circuits. The MKP386M515085JT6 is also highly durable and can withstand a wide temperature range making them suitable for industrial applications.

The MKP386M515085JT6 is an effective, reliable and cost-effective option for use in a wide range of AC and DC circuits. Its exceptional performance parameters make it the ideal choice for use in high frequency applications.
