FAQ

MLCC (Class II) product has the characteristic that capacitance is decreased when DC voltage is applied, This could be measured using the typical LCR meter.
- Measurement equipment : LCR meter E4980A + Test Fixture 16034G/E (Keysight Technologies Corp.)
- Test conditions
1) Frequency : refer to SPEC sheet for each product (e.g., 1kHz, 120Hz)
2) AC voltage: refer to SPEC sheet for each product (e.g., 1Vrms, 0.5Vrms)
3) DC voltage : from 0Vdc to Rated voltage, keep time(60sec) by each point
4) ambient temperature : 25℃ ± 3 ℃
※ Caution
1) Measurement should be proceeded after ‘pre-treatment at 150℃ for 1hour and keep at room temperature for 24hour’
*refer to FAQ “MLCC Aging phenomenon”
2) Because the voltage source of LCR meter has internal resistor, the voltage between DUT terminals may differ from setting voltage. This equipment(E4980A) provides ALC(Auto level control) function to control DUT voltage. Therefore, capacitance should be measured while ALC function is activated. If ALC function is not activated, the capacitance value may be a little low. (Figure a, b, c, d)
3) Since parasitic of the test fixture can affect on capacitance value, Short status and Open status of fixture and cable length must be properly corrected. (figure e, f)
Please refer to the user guide of the equipment for detailed measurement setting methods.

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.
