  • Do you want to check the DC bias features (valid capacitance) of a product?


    If you are curious about the DC bias features (valid capacitance), S-parameters (frequency features) based on DC voltage and temperature, or other features, please use the component library.


    The component library provides a “simulation” on electrical properties of passive components necessary for product development by researchers of application manufacturers.


    One can select the appropriate passive component without testing on a real product.



    Component Library >>


    You can check dc bias data of CL10A475KL8NRN model in our component library.


    1) Pleas enter 'CL10A475KL8NRN' in black [Part Number]

    2) Double-click the row of the model you want to select.

    3) Click the 'DC Bias' button in 'Graph Type' menu on the left.

    4) DC Bias graph is created in the new window and data can be checked or downloaded.



    We are introducing how to use the component library through video.

  • MLCCs can be distinguished by part number. An MLCC part number is generally made up of 15 digits that indicate the part’s size, capacitance, and more.

    For example, if an MLCC’s part number is “CL10A106MP8NNNC,” its size is 1.6mm in length and 0.8mm in breadth (width) while its capacitance is 10000000pF=10㎌.

    How can we know that?

    The 15 digits of MLLC part numbers has the following principle.








    series code

     It is a code that means the type of a product. ex) CL: MLCC , TC: Tantalum, etc.


    size code

     It means the length and width of a product. ex) 10: 1608 (Length: 1.6 mm, Width: 0.8 mm)


    dielectric code

     It means the temperature characteristic classification of a dielectric material. ex) A: X5R (-55 ℃ ~ 85 ℃)


    capacitance code

    It means the nominal capacitance of a product. ex) 106= 10x10^6 pF = 10000000pF = 10uFF


    tolerance code

    It means the capacitance tolerance of a product. ex) M deviation of a 10 uF product : ±20 %(8uF~12uF) 


    rated voltage code

     It is a code that means the rated voltage applicable to a product. ex) P= 10 V


    thickness code

     It means the thickness of a product. ex) 8= 0.8 mm



    /plating code

     It means the shapes of the internal/external electrodes and plating of a product. ex) N: Internal electrode (Ni) / External electrode (Cu) / Plating (Ni/Sn)


    control code

     It is a code given based on the appearance and characteristics of a product. ex) NN: General form MLCC


    packaging code

     It means the packing method for a product. ex) C : Cardboard Tape(reel type), B: Bulk type



  • 1.Searches can be done through Samsung Electro-Mechanics’ website > Products 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.

  • Capacitance of High dielectric type MLCC gradually (logarithmic scale) decreses over time. It is a phenomenon that occurs to stabilize mechanically and electrically.




    MLCC using BaTiO3 as a dielectric with a Curie temperature(about 125℃) have Characteristics of decreasing capacitance as over time (Aging) and characteristics of recovering capacitance when it was heated above the Curie temperature These characteristics tend to have larger Aging constants for MLCCs using materials with higher relative dielectric constant.




    BaTiO3 with a polycrystalline structure forms domains in a direction that stabilizes electrically and mechanically over time. Through the heat treatment or soldering process, the dielectric grains are in high energy state. (Electrical energy due to polarization, mechanical energy (stress) due to lattice distortion) This indicates an increase(recover) in capacitance. On the other hand, a dipole rearrangement occurs to form domain structure in order to reduce(stabilize) the mechanical energy (stress) over time. the response to external AC electric field weakens and the capacitance decreases gradually.

    ※ Class I type MLCCs such as C0G do not have aging characteristics.

  • The lifetime of MLCCs is affected by temperature condition and the applied DC voltage condition, It can be expressed by the following acceleration equation.




    For example, the endurance test performed under 85ºC, 16V environment is an accelerated test equivalent to 2,374.16 times under 65ºC, 4V environment. MTTF (40pcs of test sample, 60% confidence level by MIL-STD-690, JIS C 5003) is 103,562,200h, FIT is estimated to be 9.656.

    Voltage acceleration factor (‘n’) and Temperature acceleration factor (‘Ea’) used in the equation differ by the type and structure of the ceramic material.




  • The MSL is applied to plastic and IC components, not to the MLCC. Refer to the relevant international standard (J-STD-020B). 

  • Unlike MLCC, Polymer Tantalum products have no changes in capacity based on DC-Bias or high temperature environments, and are outstanding at reducing acoustic noise.
