2.2uf 185K 225VAC Metallized Polypropylene Film Capacitor 2.2 Uf

Long Stability Of Capacifance 2.2uf 185K 225VAC X2 Safety Metallized Polypropylene Film​

Safety X2 capacitors are a type of safety capacitors. Safety capacitors are used in such occasions, that is, after the capacitor fails, it will not cause electric shock and will not endanger personal safety.
1. The main structure of the X2 safety capacitor.
It is made of metallized polypropylene film non-inductive structure winding, using tinned copper clad steel wire, plastic shell and flame retardant epoxy resin package.
Polypropylene film is used as the dielectric, and the zinc-aluminum metal layer on the surface is vacuum-evaporated as the electrode. It is manufactured by winding and other processes. The exterior is packaged with (PBT) flame-retardant plastic shell and potted with epoxy resin. The appearance design is compact and suitable for high density occasion installation.

The X2 series of film capacitors are mainly used for EMI suppression by connecting the L/N of the power input, and used in parallel with the input port. The advantages are as follows:
1. This capacitor is very stable, with little change over time and stability, so the input is not easily affected by environmental factors.
2. Unlike other types of ceramic capacitors, the capacitance of film capacitors is less affected by voltage. An X7R ceramic capacitor has a capacitance change of 40% between 0V and 50% of the applied voltage.
3. Unlike most types of capacitors, film capacitors have a very low dissipation factor. This means that very little heat is generated when AC current flows through the film capacitor. The X7R capacitor converts 10% of the current flowing through it into heat, while the film capacitor is less than 0.1%.

Product structure​


Safety capacitors are used in such occasions, that is, after the capacitor fails, it will not cause electric shock and will not endanger personal safety.
It includes two types of X capacitors and Y capacitors. X capacitors are capacitors connected between the two lines of the power line (L-N). Generally, metal film capacitors are used, because metallized film capacitors are large in size, but they allow instantaneous charging and discharging. The current is also very large, and its internal resistance is correspondingly small. Ordinary capacitors have very low ripple current indicators and high dynamic internal resistance. Replacing the X capacitor with an ordinary capacitor, in addition to the capacitor withstand voltage cannot meet the standard, the ripple current index is also difficult to meet the requirements. The films used in metallized film capacitors include polyethylene, polypropylene, polycarbonate, etc., and there are also laminated types in addition to wound types. This type of metallized film capacitor has a so-called Self Healing Action, that is, if a tiny part of the electrode is short-circuited due to the fragility of the electrical interface, the electrode metal around the short-circuited part will Due to the electrostatic energy or short-circuit current carried by the capacitor at that time, it will cause a larger area of ​​melting and evaporation to restore the insulation, so that the capacitor will return to the role of the capacitor again; the Y capacitor is respectively connected between the two lines of the power line and the ground (L-E , N-E) capacitance, generally appear in pairs. Based on the limitation of the leakage current, the value of the Y capacitor should not be too large. Generally, the X capacitor is uF level, and the Y capacitor is nF level. The X capacitor suppresses differential mode interference, and the Y capacitor suppresses common mode interference.
