In 1940, people discovered ceramic capacitors and began using BaTiO3 (barium titanate) as their main material. Ceramic capacitors have excellent insulation properties, making them widely used in the field of electronics. Due to their ability to operate within a wide temperature range, ceramic capacitors became an ideal choice for both start-up small businesses and military electronic devices.

Over time, ceramic capacitors evolved into a commercial product. Around the 1960s, multilayer ceramic capacitors emerged and quickly gained market recognition. These capacitors are made by stacking multiple ceramic layers and metal electrodes, providing higher capacitance density and stability. This structure allows multilayer ceramic capacitors to occupy less space in small electronic devices while offering larger capacitance values.

By the 1970s, with the emergence of hybrid integrated circuits and laptops, electronic devices progressed rapidly. Ceramic capacitors, as essential electrical and electronic components, also underwent further development and application. During this period, the precision requirements for ceramic capacitors continued to increase to meet the signal processing and data storage needs of electronic devices. At the same time, the size of ceramic capacitors gradually reduced to adapt to the shrinking size of electronic products.

Today, ceramic capacitors hold approximately 70% of the market share in the dielectric capacitor market. They are widely used in communication equipment, computers, automotive electronics, medical devices, and other fields. Ceramic capacitors are known for their high-temperature stability, low loss, long lifespan, and excellent electrical performance. Furthermore, with the emergence of new technologies such as multilayer ceramic capacitors and supercapacitors, the functionality and performance of ceramic capacitors continue to improve.

In terms of specialization, the manufacturing process of ceramic capacitors requires strict process control and quality testing. Firstly, the selection and proportioning of raw materials are crucial for the performance of capacitors. During the manufacturing process, steps such as powder mixing, forming, sintering, and metallization are involved. Each step requires precise control of parameters such as temperature, pressure, and time to ensure the quality and stability of the capacitors. Additionally, testing for capacitance value, voltage tolerance, temperature coefficient, and other aspects is necessary to verify whether the capacitors meet the specified standards.

In conclusion, ceramic capacitors are indispensable components in the field of electronics and hold significant application value. With technological advancements and increasing demands, ceramic capacitors will continue to evolve and demonstrate their specialization and diversification in various fields.
