Film capacitors, also known as plastic film capacitors, are widely applied in products ranging from power supplies and motors to telecommunication systems and various medical equipment.

683MSR250K is a film capacitor, a three-section type capacitor, consisting of three capacitors in one with different capacitance values. The three capacitors can be connected in series and parallel to achieve the desired capacitance values.

The 683MSR250K has an approximate size of 66 mm by 55 mm and a maximum operating temperature of +85°C, making it ideally suitable for high temperature applications. It is extensively used for filtering and decoupling in high frequency power supplies, electronic control systems and mobile telecommunication systems, and for storing energy in low frequency and high voltage electrical circuits.

The working principle of the 683MSR250K is based on the same principle of a basic capacitor, which is the ability to store electrical charge. This type of capacitor consists of two metal electrodes, separated by a dielectric material. When a voltage is placed between the two electrodes, the dielectric attracts and polarizes, forming an electric field. This electric field then stores energy until the voltage is released.

The special feature of the 683MSR250K is its high dielectric strength, which is the maximum permissible voltage that can be applied to the dielectric material. The 683MSR250K uses polypropylene film as the dielectric material, which has a dielectric loss factor of 1•10-6 and a harmonic current distortion of less than 0.05%. This ensures that the capacitors are suitable for high frequency applications.

Another feature of the 683MSR250K is its low leakage current, which is the ability of the capacitor to retain electrical charge. This is achieved by using high quality polypropylene film as the dielectric material, which results in a leakage current of less than 0.1µA.

In conclusion, the 683MSR250K is a film capacitor, designed for high temperature and high frequency applications such as power supplies, electronic control systems and mobile telecommunication systems, and for storing energy in low frequency and high voltage electrical circuits. Its main features are its high dielectric strength and low leakage current, making it ideal for these applications.
