3. Electrolytic capacitor and multi-layer ceramic capacitorWe all know the requirements for quality and product life of input electrolytic capacitor, but sometimes we tend to neglect the actual quality requirements. Actually the quality of capacitor is quite influential to the lifetime of power source. Output terminal has a switching frequency as high as 60,000 times per second, which would enlarge the parasitic resistance due to heating and generate material like scale deposit, and may lead to heating temperature and explosion of electrolyte. The recommended output electrolytic capacitor is LED Lights specialized capacitor, which usually starts with the type number of L.
