Metallized film capacitors are commonly used in places where much capacity is required, such as power supply filtering, as well as the role of power storage functions. They also simulate signal connections and are widely used in noisy places, such as power supply noise. . Metallized film capacitors

Both film capacitors and metal foil capacitors are used in the market, but more are used in film capacitors. Why? According to the principle, the film capacitor generally does not have a short-circuit failure, and the metal foil capacitor often has a short-circuit failure phenomenon, so the film cap

The capacitor is an important electronic component in the circuit. When using it, be sure to pay attention to the protection and extend its service life as much as possible. Tests for withstand voltage and leakage current can be performed at the time of purchase, which can help detect the capacity o

The application of film capacitor is more and more extensive, function and quality are better and better. But we must pay attention to problems when we operate it. These are problems for film capacitors working, such as capacitor failure, problem with pitch, unclear printing, unsuitable size, etc. D

随着国家的经济越来越好，许多音乐爱好人士都会给自己配备一套大气上档次的个性音响设备，有的人甚至在装修的时候就会把音响都给安装到房间的每个角落里。也许许多音乐发烧友都没有留意到，好的音响不仅外观好，里面的音响薄膜电容也是真材实料的。 音响薄膜电容以金属化聚丙烯膜作电介质/电极绕制而成，引线则采用镀锡铜包钢线，侧面以聚酯胶带包裹，两端灌以环氧树脂，其体小质轻，稳定性十分超群，自愈性能出众，且高频损耗低。有的人可能会觉得音响这东西并不重要，能听就行了，可是他们并不知道音响可能因为电流变化的原因，因为电压、电阻影响等导致音质变差甚至音响损坏，那么不仅扫兴，而且也花钱。 但是如果音响里面有安装了品质的薄
