FAQ

  • 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.

  • As the resistance value formed during DC current applied, it is indicated as a DCR or Rdc value. The DCR is the resistance value that occurs due to the coil of the inductor. In the device, losses occur due to the resistance value during DC applied(=efficiency decrease), And it affects operation loss as heat source, so when applying to the device, you must take into consideration the loss value and heat capacity by DC resistance.
  • - Isat saturation current

    : When the DC current is applied to the inductor, the permeability of the material decreases, resulting in the decrease in inductance. Here, the DC current value at which inductance decreases by 30% compared to its default value (or nominal value) is called the Isat. Should the last value be too low, the effective inductance at the DC current is low, which may have an impact on the circuit’s operation, and therefore, it is important to select an inductor by taking into consideration the Isat margin.

     

    - Itemp temperature characteristics

    : When DC current is applied to the inductor, because of the coil’s resistance, that is, DCR, the heat and temperature of the inductor increases. Here, Itemp is the DC current value at which the temperature of the inductor increases by 40 ℃ compared to the initial value (DC 0A). If the Itemp value is too low, the component temperature of the DC current is high, and therefore, you must select the inductor taking into consideration the Itemp margin.

  • Tape or packaging materials are designed to withstand long-term storage, but it must be stored in temperature of 0~40°C and RH 0~70%. Due to excessively high temperature or humidity, product quality may drastically decrease.
    Should the relative humidity be 80% RH or higher, oxidation is accelerated, and solderability is improved as humidity decreases. Condensation may occur due to temperature differences during product storage, and therefore, you must be cautious of temperature control. 

  • The operation temperature range is -40~125°C (including self-occurrence temperature increase). You should not use it beyond the maximum operation temperature and should be careful of equipment temperature distribution and seasonal fluctuations.
