MKP385291100JD02W0 Film Capacitors

Film capacitors, also known as plastic film capacitors, are passive components made up of two parallel metal plates separated by a dielectric plastic film. The dielectric can be a solid poly, irregularly shaped poly or a metal alloy film (such as aluminum). The capacitance is determined by the size of the capacitor plates, and the dielectric constant of the material between them. The MKP385291100JD02W0 film capacitor is one of the most popular capacitors in the market.

Application of MKP385291100JD02W0

The MKP385291100JD02W0 capacitor is primarily used in DC/AC filtering applications, high frequency voltage/current control, bypass applications, delay line applications, pulse generator circuits, radio frequency interference suppression, and so on. It features low microphonic noise and high capacitance. This capacitor is often used in audio systems, power supply circuits and high frequency circuits.

Working Principle of MKP385291100JD02W0

A film capacitor functions similarly to an in-line resistor in series with a conducting path. When electricity is applied to the capacitor, it charges up to the supply voltage. This causes an electric field to form between the two conducting plates, and as a result, an electrical charge is stored on the two plates. The charge stored on the plates is determined by the capacitance of the device, which is a measure of the ratio of charge stored to the applied voltage. The MKP385291100JD02W0 film capacitor exhibits a linear relationship between capacitance and applied voltage.

Whenever the voltage drops, the stored charge in the capacitor begins to leak out, which increases the current. This current acts as an impedance in the circuit and reduces the rise of the applied voltage, thus limiting the flow of current. This allows the capacitor to act as a buffer, dampening the effect of voltage fluctuations in the circuit. In other words, the MKP385291100JD02W0 film capacitor acts as a filter and blocks unwanted AC signals, allowing only the desired AC signals to pass while attenuating the rest. This is why it is often used as a filtering device in audio and power circuits.

Conclusion

In conclusion, the MKP385291100JD02W0 film capacitor is a popular choice for filtering and voltage control applications due to its high capacitance and low microphonic noise. Its working principle is to charge up to the supply voltage and act as an impedance in the circuit, thereby limiting the flow of current and attenuating undesired AC signals. With its wide application in audio systems, power supply circuits and high frequency circuits, the MKP385291100JD02W0 film capacitor is a must-have for any engineer.
