Film capacitors are capacitors in which metal foil is used as electrodes, and plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate are covered from both ends and then wound into a cylindrical structure. Based on the type of plastic film, film capacitors can be divided in to polyethylene capacitors (also known as Mylar capacitors), polypropylene capacitors (also known as PP capacitors), polystyrene capacitors (also known as PS capacitors) and polycarbonate capacitors.
With the development of automobile electrification, the voltage and output power of automobile circuit systems have been significantly improved, and key components become stricter with voltage and impact resistance of electronic components. Change in working conditions put forward new requirements on the performance of the capacitor components in the electronic system, thereby stimulating the demand for metal film capacitors in the automotive industry.
Some automotive products have replaced the aluminum electrolytic capacitors with film capacitors. On one side, the film capacitor's withstand voltage and impact resistance characteristics make it suitable for use in the electrical environment of new energy vehicles. On the other side, the size and weight of film capacitors have been reduced by 3 to 4 times compared to original models, and the metallization segmentation technology has been improved at the same time, which has greatly promoted the development of film capacitors. Nowadays, film capacitors can cover the voltage range between 600VDC-1200VDC more economically than electrolytic capacitors.
Therefore, it can be predicted that the prospects of film capacitors is quite promising since their performance and size can meet the needs of many industries. It would be much recommended that you should choose a qualified manufacturer to purchase film capacitors because in this way the quality of film capacitors can be guaranteed.
Dongguan Zhixu Electronic Co., Ltd. (JEC) would be a foolproof choice if you don't know which manufacturer to choose. JEC has passed ISO9001:2015 quality management system certification. Its safety capacitors (X and Y series) and varistors have passed authoritative certifications of many countries and its ceramic capacitors and film capacitors are in line with environmental protection directives.
We are often imitated but never surpassed. JEC has over 30 years experience of manufacturing ceramic capacitors. You wouldn't regret if you choose us. If you have technical questions or need samples, please contact us.
