SAMSUNG ELECTRO-MECHANICS

First, let's briefly introduce the ideal frequency characteristics of the passive elements (R, L, and C).

Resistance (R) has the property of impeding the flow of current, causing a voltage drop proportional to the magnitude of its impedance.

The impedance value is the same regardless of the frequency.

 Inductance (L) has the characteristic that the current gradually increases when a voltage is applied, and the impedance increases as the frequency of the applied electrical signal increases.

In a real MLCC, there are parasitic components (resistance and inductance) as well as capacitance. 

Here, the resistive component of the dielectric or electrode is called the equivalent series resistance (ESR), and the inductive component of the electrode or lead wire is called the equivalent series inductance (ESL).

An equivalent model of these components can be constructed as a circuit with C, ESR, and ESL in series, as shown below.

A graphical representation of the MLCC's impedance (Z) as a function of frequency shows two distinct regions centered on the self-resonant frequency (SRF) as shown below.

In the low frequency region, capacitive reactance dominates, and dielectric loss is also observed. 

The impedance of parasitic components such as ESL is small enough and can be neglected.

However, in the high frequency region, the parasitic inductance can no longer be neglected, and resistive losses due to the skin effect and proximity effect of the current also start to appear. 

The frequency at which the capacitive and inductive reactance components cancel out is called the self-resonant frequency (SRF).

Capacitors whose function is to remove noise from the power line and suppress voltage fluctuations are often required to have a specific target impedance in high frequency noise sensitive applications such as PDN.

In general, MLCCs have lower ESL and ESR characteristics than electrolytic capacitors and film capacitors, allowing for more efficient noise cancellation by using MLCCs in these locations.

As the performance requirements of the APs increase, MLCCs are often used in parallel or placed as close to the AP as possible to achieve smaller ESL and ESR characteristics. 

In addition, Samsung Electro-Mechanics has 3-terminal MLCCs and Reverse type MLCCs in the Low ESL product family, which provide a solution that saves space with a smaller mounting area than typical MLCCs, and reduces the number of components to be placed.

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.

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.

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℃
