The 1345310404 or MKP-1845310404, hereinafter referred to as “M”, is a kind of film capacitor, which is composed of a metalized polypropylene film dielectric and a polypropylene film outer sleeve, with both ends sealed with epoxy resin, metal leads and plastic molding parts, and its essentially complete components of a capacitor. It has been widely used in the fields of high and low power electronic engineering design in recent years.

The broad application fields of M includes circuit filters, DC power supply filtering, Circuit Coupling, Radiation Protection, Humidity Protection, anti-interference and other electronic components design application fields.

• Circuit filters: M is mainly used in the circuit filters of power factor correction, which is widely used in various high power or low power circuit designs, such as in-phase pump, single-phase triode dynamo, high frequency switching power supply, etc.
• DC power supply filtering: M can be used in power supply filter of DC circuit board in order to reduce the noises and improve the working efficiency of the appliance.
• Circuit Coupling: In the conventional power amplifier circuit, the blocking capacity provided by M can reduce the direct current leakage caused by coupling between the two stages, so as to avoid signal distortion.
• Radiation Protection: M can help to reduce the disturbance of electromagnetic waves on the signal, so as to reduce the adverse effect caused by the external environment noise.
• Humidity Protection: In humid climate, relative humidity has an impact on the stability and life of the equipment. M can effectively prevent the corrosion and damage of the metal lead caused by high humidity and keep the normal operation of the circuit.
• Interference Protection: M can reduce the impact of the switching circuit of the electronic appliance on the signal. This prevents the circuit from interfering with the signal, thereby ensuring a stable performance of the circuit.

When M is added to the electronic circuit, due to the dielectric barrier between the two metalized surfaces of the polypropylene film, the dielectric barrier will be filled with current, resulting in an accumulation of charge. This charge is used to block and reduce the noise of the signal, and when the magnitude of the signal changes, the accumulation of charges will quickly adjust to maintain the signal amplitude, so as to protect the circuit.

To sum up, M film capacitor is an important component of electronic circuit design, with a variety of application in filter, DC power supply, anti noise and other fields. It has a stabile performance and can effectively and long-term protect the circuit from external interference, so it wins the recognition of designers and has become the necessary components of electronic design.
