8532.24.0020

8532.24.0020（https://www.sic-components.com/product/search?search=GRM1555C1H2R6WA01D+） is a commodity code belonging to the HS Code (Harmonized System Code) system.
The HS Code is an internationally - recognized commodity classification system maintained and managed by the World Customs Organization (WCO). It is used to uniformly identify and classify commodities in international trade. It consists of a six - digit basic code, and countries can add additional digits after the six - digit code for more detailed classification according to their own circumstances.
In China, the import and export tariff regulations adopt a ten - digit code. The first eight digits are equivalent to the HS Code, and the last two digits are China's sub - headings. The first six digits "853224" in 8532.24.0020 represent multilayer ceramic capacitors, which is the international standard part of the HS Code. According to relevant information, 8532.24.0020 specifically corresponds to the multilayer ceramic capacitor model GRM1555C1H2R6WA01D （https://www.sic-components.com/product/search?search=GRM1555C1H2R6WA01D+）produced by Murata. This capacitor has a capacitance value of 2.6pF, a voltage rating of 50VDC, and a dielectric of C0G (NP0).

GRM1555C1H2R6WA01D Structure and Principle https://www.sic-components.com/product/search?search=GRM1555C1H2R6WA01D+
Structure: Multilayer ceramic chip fixed capacitors are formed by laminating ceramic dielectric diaphragms printed with electrodes (inner electrodes) in a staggered manner. After a high - temperature sintering, a ceramic chip is formed, and metal layers (outer electrodes) are encapsulated at both ends to form a monolithic - like structure, so it is also called a monolithic capacitor. Its internal structure is a multi - layer structure composed of multiple simple parallel - plate capacitors connected in parallel. The capacitance is increased by increasing the number of laminated layers to achieve miniaturization.
Principle: Based on the basic principle of capacitors, that is, a capacitor is formed when an insulating medium is sandwiched between two closely - spaced conductors. When a voltage is applied across the capacitor, charges accumulate on the electrodes, thereby storing electrical energy. Multilayer ceramic chip fixed capacitors utilize the high dielectric constant of the ceramic medium and the multi - layer structure to increase the electrode area, achieving a large capacitance with a small volume.

GRM1555C1H2R6WA01D Characteristics and Advantages https://www.sic-components.com/product/search?search=GRM1555C1H2R6WA01D+
Small size and high specific capacitance: With the development of electronic devices towards miniaturization and high - performance, the requirements for the size of electronic components are becoming more and more stringent. Multilayer ceramic chip fixed capacitors can achieve a large capacitance in a very small volume through multi - layer stacking technology, meeting the miniaturization requirements of electronic devices. For example, each smartphone typically uses about 1000 such capacitors.
Good high - frequency characteristics: They have low high - frequency impedance and low equivalent series resistance (ESR), can maintain good performance in high - frequency circuits, reduce signal distortion and energy loss, and are suitable for high - frequency, radio - frequency, and precision measurement applications.
High reliability: The ceramic medium is sintered at high temperature, with a dense structure, good stability, and corrosion resistance. It can maintain stable electrical performance in different working environments and has a long lifespan, meeting the reliability requirements of various military and civilian electronic devices.
Excellent temperature characteristics: According to different ceramic dielectric materials, products with various temperature characteristics are available. For example, capacitors with NPO (COG) dielectric materials have a very small and linear change in capacitance with temperature, and are suitable for oscillator circuits and time - constant circuits with high requirements for capacitance stability. Capacitors with X7R dielectric materials have a capacitance change of only 15% in the temperature range from - 55°C to 125°C, with good temperature stability, and can be used in general electronic circuits.
