Development status of film capacitors in the home appliance industry

Film capacitors have the advantages of self-healing, non-polar, and strong insulation. In the home appliance industry, what is the data status of film capacitors in 2018?

Demand for home appliances in China has steadily increased. Such as conditioners, film capacitors are mainly used in motor startup and other circuit control parts. According to national statistics, China's air-conditioning output in 2018 was 205 million units, a year-on-year increase of 1.356%. On the one hand, the consumption upgrade drives the demand for air conditioners and the frequency conversion air conditioner rate to increase simultaneously. On the other hand, fixed frequency to frequency conversion, air-conditioning circuit board control increased, and the use of film capacitors increased. Downstream demand The steady growth of traditional applications in the field of home appliances has ensured stable demand for film capacitors.

China's LED lighting output in 2018 was 76.92 million. With reference to the "firefly" energy-saving lamp usage, 5 film capacitors are required in a single energy-saving lamp. In LED lighting, film capacitors will only be used for lamps above 8w, and the required amount is less than energy-saving lamps. Therefore, the rising LED rate will bring down the demand for lighting. However, the LED rate continues to rise, and the demand for lighting film capacitors in the future will slow down.

According to data from the China Automobile Industry Association, in 2018, the production and sales of new energy vehicles in China completed 1.27 million and 1.256 million units, respectively, an increase of 59.9% and 61.7% year on year. The trend of continuous improvement has put forward higher requirements on the performance of DC supporting capacitors. Film capacitors have better performance than aluminum electrolytic capacitors, and film capacitors have replaced aluminum electrolytic capacitors as the preferred DC support capacitor for new energy vehicles. In summary, the rapid development of the new energy automobile industry has provided new development momentum for film capacitors.

From the data of these three industries, we see that the number of film capacitors we use is increasing. As a manufacturer, we need to pay attention to the quality of film capacitors.
