Film Capacitors

Film capacitors are a type of capacitor that makes use of a polyethylene-terephthalate (PET) film as an insulating layer between two or more conductive layers of electrode material. This type of capacitor offers excellent features such as excellent self-healing properties, low ESR (equivalent series resistances), low electrical noise generation, long lifespan and low failure rate. The MKP1839282403 is one such type of capacitor and its application field and working principle will be described in more detail below.

MKP1839282403 is a non-polimorphic (also known as “self-healing”) polypropylene film capacitor. These types of capacitors are designed to self-heal cracks generated in the film layer due to current surges or other overload conditions. The MKP type also offers low losses (thanks to the low ESR which is only a fraction of other capacitor types), and low electrical noise generation. The MKP1839282403 can be found in many applications, such as switched-mode power supplies (SMPS) and various industrial applications.

The working principle of the MKP1839282403 film capacitor is similar to that of any other type of capacitor. A dielectric material (in this case, the polypropylene film) is inserted between two metal electrodes. When an electric potential difference is applied across the two electrodes, the electric field established within the dielectric causes the electrodes to become charged and hence store energy. The electric field also prevents current from passing through the dielectric, allowing the capacitor to function as a filter, blocking any direct current in the circuit.

The operating voltage of the MKP1839282403 capacitor is usually rated at 380Vac with 6-15μm thickness and 38-53mm width. The tolerances (variable between +/-5-15%) and temperature characteristics are also designed to meet the specific requirements of the application. The MKP1839282403 is usually able to produce up to 97.5% of rated voltage while maintaining its safety characteristics, which makes it suitable for many different types of industrial applications. In addition to its relatively high capability, this capacitor is also known for its stability in the long-term, due to its self-healing properties. This makes it ideal for applications such as motor control applications, UPS systems or any other applications where the conditions might fluctuate considerably.

The MKP1839282403 film capacitor is a versatile and reliable component and its application field and working principle have made it highly sought-after in both industrial and commercial applications. Its self-healing properties make it ideal for many situations where changing load conditions could potentially lead to failure, and its low electrical noise generation ensures that the system runs smoothly and quietly. Finally, its long lifespan and low failure rate make it an excellent choice for any electrical system where downtime and maintenance costs need to be kept to a minimum.
