Requirements for selection of film capacitors used in LED lighting products
There are many kinds of LED lighting products, such as bulb, fluorescent lamp, industrial lamp, street lamp, etc. Some products have small space and high temperature, so the required capacitors should also have small volume, high temperature resistance and good current and voltage resistance.


LED products inside the space is little, slow cooling, use for a long time will cause temperature backlog, need small volume, high temperature resistant film capacitor, but ordinary film capacitor heat resistance at 85 ℃ on the market, may can't stand high temperature making internal dielectric film contraction deformation, cause the loss of capacitor capacity and voltage current resistance. So choose 110 ℃ material film capacitor, the film capacitance extreme heat resistance up to 120 ℃.


Generally like the roadside LED lights, factory lights, etc., in 24 hours long power, and thin film capacitors because of the structure of the reason, the long time will make the capacity has a certain degree of attenuation, especially in the occasion of resistance and capacitance voltage reduction. The main reason is that when the film is wound, the gap between the film and the film will generate ozone when the film is electrized for a long time. After accumulation, the metal layer will be oxidized and the capacity will decrease. So capacitance during production by high temperature hot pressing to reduce internal space, improve the sealing performance of capacitance, choose plastic coating products.


Common on the market of polyester film capacitor loss is high, temperature can reach more than 10 ℃, if long time used for communication breakdown, easy to heat the wastage of the capacitance than polyester and polypropylene film capacitor is 10 times smaller, low temperature rise, high resistance to impact strength, under the condition of high frequency ac has a good compression performance, so try to use polypropylene capacitor.
