  • When you go to the Contact us on the main page or the Product page, you can ask questions about technologies and purchases by each region.  

  • 1) Searches can be done through Samsung Electro-Mechanics’ website > Product Search.

    2) Product searches can also be done through the Google search window. Input passive component P/N in the search window > Click on the ‘Samsung Electro-Mechanics : Product Information’ from among the search results > Relevant product page opened 

  • If the product you want has been discontinued, our website allows you to search for substitute products. For example, if you’re looking for a substitute for CL10A106MP8NNNC with the same size and capacity, you can follow these steps.


    1)First, you need to understand the Part Numbering System rules. If you don’t remember, click the question mark icon on the Product Search menu, and an information window about the Part Numbering System will pop up.

    2)The numeric values included in a Part Number indicate certain attributes.




    Size is indicated by the third and fourth digits in the number. '10' corresponds to 0603(1608), which means 1.6 mm × 0.8 mm. Capacity is indicated by the sixth through eighth digits. '106' means 6th power of 10×10; that is, 10,000,000 pF = 10.㎌.



    With the spec. information you gave, it is difficult to share the exact part.(need size tol and additional info.)

    I recommend you to use our web library.

    If you use our library below, you can select the model you want to check the electrical performance.



  • 1) Go to “Product Search,” and click on the tab for the product you want.

    2) Enter the Part Number (e.g., CLL5Z105MS3NLNH) to begin the search.

    3) When the search results are displayed, check the “Status” section to see if the product is in “Mass Production” or “Under Development.” In most cases, products not included in the search results are “Discontinued Products.” However, there are some products that are not displayed for other reasons. It would be a good idea to contact our staff to see if it has been discontinued.

  • There is no specification for allowable current of MLCC.
    When DC voltage is applied into MLCC, there is no issue since almost no current flows through the MLCC, however, when the AC voltage or pulse voltage is applied, the current flows through the electrode which leads to generate heat. Therefore, check the self-heating temperature by input AC or pulse voltage when the capacitor is used.


    2-6. Self-heating Temperature ( in Datasheet)
    It is necessary to design the system, with considering self-heating generated by the ESR (Equivalent Series Resistance) of MLCC when AC voltage or pulse voltage is applied to MLCC.
    2-6-1. When MLCC is used in an AC voltage or pulse voltage circuit, self-heating is generated when AC or pulse current flows through MLCC. Short-circuit may be occurred by the degradation of MLCC’s insulating properties.
    2-6-2. The reliability of MLCC may be affected by MLCC being used in an AC voltage or pulse voltage circuit, even the AC voltage or the pulse voltage is within the range of rated voltage.
      Therefore, make sure to check the following conditions.
    1) The surface temperature of MLCC must stay within the maximum operating temperature after AC or Pulse voltage is applied.
    2) The rise in increase by self-heating of MLCC must not exceed 20℃


  • The insulation resistance is the resistance of dielectric material of MLCC. The insulation resistance value is calculated by dividing the rated voltage by the leakage current, and the leakage current is the current flows both electrodes when the rated voltage is applied. Insulation resistance is generally MΩ values, and when the voltage is applied., as shown in the picture, First, current is charged both electrode of MLCC, and therefore, insulation resistance is measured 60 seconds after the voltage is applied.


  • The capacitance value of MLCC is determined by the number of dipoles in the dielectric that are aligned at both ends of the electrode when voltage is applied as shown in the figure below. When AC voltage is applied, the capacitance value increases in proportion to the number of dipoles that move (align) according to the AC voltage. the meaning of capacitance is C=Q/V, which represents the amount of electric charge accumulated on the electrode when a voltage is applied to the MLCC.


    In the case of C0G, a Class 1 type, there is no change in capacitance even when DC voltage is applied.
    However, in the case of Class 2 (X5R, X7R, etc.) type, the capacitance gradually decreases as the DC voltage increases as shown below.
    The reason is that when a DC voltage is applied, the dipoles in the dielectric are aligned and fixed according to the direction in which the voltage is applied, thereby reducing the number of dipoles that move to voltage changes (AC voltage) It is proportional to the number of dipoles reacting to AC voltage.) As the applied DC voltage increases, the number of dipoles aligned and fixed increases.
    As a result, as the number of dipoles for implementation of capacitance decreases, the capacitance value gradually decreases.


  • The Capacitance value of MLCC gradually decreases over time, but it does not decrease in proportion to normal time but decreases in proportion to logarithm time as shown in the diagram.



    This is a part of the process in which mechanical stress is diminished within the MLCC molecular structure, forming a 90˚ dipole. In accordance, the degree of freedom of the dipole of dielectric within the MLCC gradually decreases, and even if the AC voltage for capacitance measurement is applied. the dipole gradually fails to move, resulting in a decrease in of capacitance value.
