This document specifies the Multilayer Chip Ceramic Capacitors, general series. It details the classification of capacitors and dielectric materials, product structure, naming conventions, capacitance ranges for various sizes (0402, 0603, 0805, 1206, 1210, 1808-1812, 2220-2225), product dimensions, technical requirements and test conditions, product packaging, and usage precautions for MLCCs.
1. Capacitor and Dielectric Material Classification
COG (Class I): Stable electrical properties, minimal change with temperature, voltage, and time. Suitable for low-loss, high-stability circuits (filters, resonators, timing circuits).
X7R, X5R (Class II): High dielectric constant, higher capacitance than Class I. Stable temperature characteristics. Suitable for wide capacitance ranges where high stability is not critical (DC-blocking, coupling, bypassing, frequency discriminating).
Y5V (Class II): Highest dielectric constant, but poor capacitance stability. Sensitive to temperature and voltage. Suitable for applications requiring large capacitance where moderate losses and capacitance changes are acceptable.

1. Ceramic Dielectric
2. Inner Electrode
3. Outer Electrode
4. Nickel Layer
5. Tin Layer
3. Product Specification Naming Rule
TCC (Code of Ceramic Capacitor) + Chip Size (e.g., 0805) + Type (COG, X7R, X5R, Y5V) + Capacitance (e.g., 105 = 10 x 10^5 pF) + Capacitance Tolerance (A, B, C, D, F, G, J, K, M, Z) + Rated Voltage (e.g., 500 = 50VDC) + Thickness (A, B, C, D, E, F, G, H, M) + Packing (B: bulk, T: tape)
