LED lighting requirements for film capacitors

1. Pay attention to the temperature characteristics of the capacitor

LED lighting products include bulbs, fluorescent lamps, street lamps, industrial and mining lamps, etc. After the lamps are lit, the heating temperature of the lamp beads will rise to 80 degrees or more. If the low-temperature film capacitors of the highest recognition on the market are 85 degrees, it is easy. The explosion occurred due to excessive temperature. Our company is doing high temperature film capacitors above 105 degrees, which can definitely meet the high temperature requirements.

2. High stability and long life

Because LED lighting products have a long working time, some even work continuously, so there are certain requirements for the stability and life of the capacitor. After years of research, our company produces film capacitors regardless of stability or life. All of them can meet the requirements of customers, but customers should also pay attention to the correct specifications according to their own circuit design and use occasions.

3. Resistor-capacitor step-down capacitors must not have significant capacity attenuation

The power supply with the RC solution is a relatively low-end product. The purpose is to save the transformer and save costs. However, this solution has a very high requirement for the capacitor used to resist the buck. Resistor-capacitance step-down is the need to charge and discharge the capacitor continuously. The probability of capacity decay of the capacitor for such a long time operation will be large. Our current LED-specific products are very mature in LED applications and can fully meet customer requirements.
