Film capacitors, also known as plastic film capacitors, are named for the polyester film that makes up their dielectric layers. Also known as the MKP386M540100YT4, film capacitors are widely used in a variety of electronic applications, ranging from audio equipment to power supply circuits. The unique characteristics of film capacitors make them ideal for many applications.

Property and Working Principle of MKP386M540100YT4

A film capacitor has a dielectric layer of polyester which is laminated between two metal electrodes (Pins) to create a dielectric barrier. A voltage is applied to the capacitor which creates a capacitance which is proportional to the area of the electrodes and the dielectric constant of the dielectric material. This capacitance is then used to store electrical energy (charge). The main advantage of film capacitors is their low tolerance, reliability and temperature coefficients.

The MKP386M540100YT4 film capacitor has a dielectric of polyester and an operating temperature range of -55C to +105C. It is an axial-leaded capacitor with a current rating of 3mA. Its capacitance range is from 0.068uF to 15uF. The main benefit of this type of film capacitor is its high insulation resistance and low electrical leakage. The leakage current is typically 0.02mA or less at rated voltage.

Application field of MKP386M540100YT4

The MKP386M540100YT4 film capacitor is mostly used in high frequency circuits, where its low signal loss and high insulation resistance excel. It is suitable for use in audio equipment, power supplies, and in EMC (Electro Magnetic Compatibility) circuits. It is also used in coupling and bypass circuits, and can be used as a filter capacitor in high frequency signal conditioning circuits.

The MKP386M540100YT4 is also used in motor control circuits, such as electric fans and printers. Its high insulation resistance and stability over temperature make it particularly suited to these applications. The capacitor is also widely used in switching power supplies for its low inductance-keep-out area, which helps reduce EMI (ElectroMotive Interference) noise from the power supply.

Film capacitors are also used as safety devices in higher power circuits due to their low fire hazard ratings. This may be particularly important in medical equipment, where the risks of fire or electric shock are high. The MKP386M540100YT4 has the highest safety ratings for such use.

Conclusion

The MKP386M540100YT4 film capacitor is a widely used device, suited to a variety of high-frequency and signal conditioning circuits. Its unique properties make it ideal for use in audio equipment, power supplies, motor control circuits, and medical equipment. Its low tolerance, reliability, and fire hazard ratings make it especially suitable for safety-critical applications. The MKP386M540100YT4 is an excellent choice for any number of applications.
