Trends in Cbb20 Polypropylene Safety Capacitor


フィルムコンデンサは、アルミなどの金属箔を電極に、プラスチックフィルムを重ねて巻く方法が一般的です。 プラスチック フィルム コンデンサの中で最も優れた特性を持っているのはポリプロピレン コンデンサであり、当然価格も比較的高くなります。 しかし、近年、品質を向上させるために、使用される部品と材料はますます高度になり、価格は考慮すべき最も重要な要素ではないため、近年、PPコンデンサの頻度と量が減少しています。ますます高くなる。

Due to the electrical impedance of a capacitor decreasing with frequency, they are an efficient component for reducing interference because at higher frequencies, they short circuit electrical noise and transients between the lines or to ground. As a result, they shield machinery and equipment from electromagnetic and radio frequency interference as well as transients in across-the-line (X capacitors) and line-to-ground (Y capacitors) connections. This includes motors, inverters, electronic ballasts, solid-state relay snubbers, and spark quenchers. Interference that is symmetrical, balanced, or differential can be successfully absorbed by X capacitors. To counteract asymmetrical, unbalanced, or common-mode interference, Y capacitors are linked in a line bypass between the line phase and a point of zero potential.

We know that Cbb20 polypropylene safety capacitor have a great advantage, that is, they have self-healing properties, that is, if there is a problem inside the capacitor, it can achieve self-healing and can be used normally, but film capacitors also have a disadvantage, that is, film capacitors The capacity will be reduced, especially for the resistance-capacitance step-down circuit. If the quality of the film capacitor is not good, the capacity attenuation will be very serious.
