in fact, since 2017, aluminum electrolytic capacitors have been in short supply. fortunately, the factory can adjust production plans to meet the needs of large enterprises. but with the outbreak of covid-19, a series of problems, such as factory shutdown, have appeared. three and electrolytic capacitors have been in short supply.
according to statistics, the application fields of aluminum electrolytic capacitors in the world are consumer electronic products accounting for 45%, industry accounting for 23%, information 13%, communication 7%, automobile 5% and others 7%. consumer aluminum electrolytic capacitors are mainly used in consumer markets such as energy-saving lighting, television, display, computer and air conditioning; industrial aluminum electrolytic capacitors are mainly used in industrial and communication power supply, professional frequency converter, numerical control and servo system, wind power generation, automobile and other industrial fields.
from the application of aluminum electrolytic capacitor, it can be seen that due to the limitation of volume, aluminum electrolytic capacitor will not appear in portable fmcg products, but more in industries, automobiles, household appliances, lighting and other fields. the demand in these application fields basically will not appear in super large-scale applications such as smart phones. even in the rapidly growing application demand such as charging piles in the past two years, the capacity expansion of aluminum electrolytic capacitors can basically keep up.
the rapid popularization of led lighting, the rapidly expanding new energy vehicle charging pile market and the use of variable frequency air conditioning are the main reasons for the increase in the demand for aluminum electrolytic capacitors in the past two years. in addition, automotive led lighting, frequency converter and cnc servo system are also the needs of national energy conservation and emission reduction and intelligent manufacturing policy support, which also greatly promotes the market growth of aluminum electrolytic capacitor. over the past years, the situation of oversupply of aluminum electrolytic capacitors has been changed.
however, the most fundamental reason is that the environmental storm has led to the rectification or closure of most small processing plants, resulting in a sudden sharp reduction in production capacity within a year. subsequently, large factories are also facing tight production capacity. aluminum foil is an important raw material for aluminum electrolytic capacitors. in the past year, the price has increased by nearly 30%. not only the price of aluminum foil, guide pin, aluminum shell, cover plate and electrolyte are also rising, and the price of electrolytic paper is also rising, which may be that the price of packaging film has not increased.
the price of raw materials for aluminum electrolytic capacitors has been rising. in addition, affected by the epidemic in recent years, the work of the factory has also been affected to a certain extent. therefore, the price of aluminum electrolytic capacitors has also increased. coupled with the rapid development of various industries and the surge in demand, the delivery time of sanhe electrolytic capacitors has also been slightly extended. here, shandong hongbao electronics reminds our customers, if it is necessary to purchase sanhe electrolytic capacitors, it is recommended to prepare the goods in advance to avoid delaying production due to delivery time.
