MKP383413040JFP2B0

Film capacitors, also known as plastic film capacitors, are passive electronic components composed of thin dielectric films, and are mainly used as signal coupling and decoupling in communication circuits, for circuit isolation, and for timing control in oscillators. The MKP383413040JFP2B0 is one such film capacitor and is a lead-free variant.

The MKP383413040JFP2B0 is a polypropylene film, metallized AC capacitor with a maximum working voltage of 400V AC and a capacitance of 3.3nF (3.3µF). With its long useful life, superior temperature characteristics, excellent safety performance and heat resistance in combination with a low dissipation factor and low self-inductance, the MKP383413040JFP2B0 is suitable for use in a variety of electronic devices. It can be used in applications ranging from power supplies to radio and television equipment, intercom systems, aircraft, medical appliances, telephones, general electrical equipment, appliances, amplifiers, oscillators, and other related devices.

The working principle of film capacitors utilises the ability of electrical conduction in layers of dielectric films. A film capacitor is constructed of two electrodes, which are separated by a dielectric layer. When a voltage is applied across the electrodes, an electric field is generated in the dielectric layer. This electric field causes a current to flow from one electrode to the other. The current causes electrons to flow along the electrode surface which creates an electric charge, allowing for the capacitor to store energy.

The MKP383413040JFP2B0 is designed to be connected in series with inductive loads to provide snubbing and decoupling. In this application it acts as a voltage-dependent resistor, limiting the current and frequency of spikes and preventing damage to sensitive components from fast transients. It is also commonly used for power supply smoothing and filtering in batteries, motor drives, and photovoltaic energy conversions.

The MKP383413040JFP2B0 is also suitable for AC operated circuits due to its high insulation resistance, good heat resistance and low impedance characteristics. Its excellent dielectric strength, high ripple current and low temperature coefficient of capacitance (TCC) make it especially suitable for applications such as voltage stabilisation in audio-visual equipment, lighting equipment, LED SMD boards, and other high-frequency switching power applications.

In summary, the MKP383413040JFP2B0 film capacitor is suitable for a wide range of applications such as power supplies, radio and television equipment, intercom systems, aircraft, medical appliances, telephones, general electrical equipment, appliances, amplifiers, oscillators and other related devices. It is specialised for AC operated circuits due to its high insulation resistance, good heat resistance and low impedance characteristics. The MKP383413040JFP2B0 is designed to be connected in series with inductive loads to provide snubbing and decoupling as well as power supply smoothing and filtering in batteries, motor drives, and photovoltaic energy conversions.
