1. In the ultra-small size, high-capacity and high-voltage series of chip capacitors, the advantages of Japanese manufacturers are more obvious. For example, the number of ceramic laminates of chip capacitors can be 1,000 layers by Japanese manufacturers, while domestic chip capacitors can only achieve about 300 layers. Although the gap is not visible in the medium voltage conventional series, there is a significant gap in high capacity, high pressure and stability.
2. The consistency of large quantities of chip capacitors. The production of basic components such as chip capacitors and chip resistors in the same batch is more than one million. The most difficult to ensure such a huge number is consistency. Japanese chip capacitors are more perfect in details such as raw materials, process and quality control.
3. In terms of raw materials, the domestic entry into the electronics industry is relatively late, and materials are the shortcomings of Chinese electronic component companies: ceramic slurry involves many ceramic materials such as barium titanate and titanium oxide, and is also mixed with organic glue, etc., electrode slurry is mixed with nickel Powder, copper powder, resin, etc., all formulations need to be studied. Japan focused on consumer electronics after World War II. Japanese chip capacitor manufacturers Murata and Kyocera started with materials and did not start manufacturing chip capacitors until they made the highest quality ceramic paste and electrode paste.
Japanese chip capacitors are the leader in the entire chip capacitor market, accounting for more than 50% of the total market share, and are positioned in the high-end market. South Korea and Taiwan chip capacitors are second, mainly in the mid-end market; while domestic chip capacitors are Can only go to the low-end market with a price advantage.
Japanese chip capacitor manufacturers that have adhered to basic research and development for decades have always set their sights on the high-end market. From the end of last year to now, the price of chip capacitor resistors has skyrocketed because several Japanese chip capacitor manufacturers abandoned conventional products with lower profit margins. , Put the production capacity on ultra-small size chip capacitors for mobile phones and car-grade chip capacitors for automobiles. These two categories have huge market potential but higher technical thresholds. Based on the analysis of the current situation, the basic components of these two major industries may continue to be controlled by Japanese SMD capacitor brands in the future.
