CL21A106KQFNNN Multilayer Ceramic Capacitor Model Information

1. Product Series: CL Series (Multilayer Ceramic Capacitors)
2. Size Code: Corresponding to 0805/2012 (2.00mm x 1.25mm in metric dimensions). This size code indicates the physical dimensions of the capacitor, which are important for PCB (Printed Circuit Board) layout and component placement.
3. Dielectric Material: X5R. X5R is a high - dielectric - constant material. It has a capacitance change within ±15% over a temperature range of -55°C to +85°C, making it suitable for applications where capacitance stability over a moderate temperature range is required, such as in power supply filtering circuits in various electronic devices.
4. Capacitance: 10μF. The capacitance value is specified as 10 microfarads. This indicates the ability of the capacitor to store electrical charge. In electronic circuits, different capacitance values are used depending on the requirements of the circuit, such as coupling, decoupling, or filtering applications.
5. Capacitance Tolerance: ±10%. The tolerance of ±10% means that the actual capacitance of the capacitor can vary within 10% of the nominal value (10μF in this case). For example, the actual capacitance could range from 9μF to 11μF.
6. Rated Voltage: 6.3Vdc. This is the maximum voltage that the capacitor can withstand continuously without significant degradation or failure. It is crucial to ensure that the operating voltage in the circuit does not exceed this value to avoid damage to the capacitor.
7. Thickness: Not explicitly given in the provided data for this specific part number in a dedicated thickness field, but for the 0805/2012 size, common thickness values might be considered (e.g., 0.65mm, 0.85mm, etc., depending on the product variation).
8. Inner Electrode/Termination/Plating: Inner electrode and termination materials are standard (Ni - Cu in many cases for normal - type capacitors), and the plating material is Ni/Sn 100%. These materials are chosen for their good electrical conductivity and soldering properties, ensuring reliable electrical connections in the circuit.
9. Product Code or Size Control: Normal (as inferred from the lack of special indication otherwise). This likely indicates a standard - type capacitor without any special array or low - inductance features.
10. Packaging: Not specified in the given data. However, common packaging types for MLCCs include cardboard tape (paper) and embossed tape (plastic), with various taping types like normal 7" reel, 1mm pitch 7" reel, etc.
11. Reliability Level: Not provided in the given data. But generally, reliability levels are tested based on conditions such as humidity tests (e.g., 40°C, 95%RH, 1Vr, 500h for standard level), high - temp load tests, board flex tests, and temp. cycling tests. These tests ensure the long - term performance and stability of the capacitor under different environmental and operational conditions.
