There are many factors that need to be considered when selecting capacitors. The following discusses the capacitor selection elements of MLCC.

MLCC selection: Just meeting the parameters is not enough.
The general decision-making logic for purchasing a product is: whether it can be used, whether it is easy to use, whether it is durable, and the price. In fact, this logic can also be applied to the selection process of MLCC: firstly, the MLCC parameters must meet the circuit requirements, and secondly, whether the parameters and media can make the system work in the optimal state; Besides, is there any defective product in the incoming MLCC and how reliable is it; Finally, is there an advantage in price and is the supplier's cooperation timely. Many design engineers do not attach importance to passive components, thinking that only theoretical calculation of parameters is sufficient. In fact, the selection of MLCC is a complex process, and it is not simply satisfying the parameters.

Selection Elements
-Parameters: capacitance value, tolerance, withstand voltage, operating temperature, size
-Material
-DC bias effect
-Failure
-Price and Supply

The performance of different media determines the different applications of MLCC
-C0G capacitors have high temperature compensation characteristics and are suitable for use as bypass capacitors and coupling capacitors
-The X7R capacitor is a temperature stable ceramic capacitor, suitable for industrial applications with low requirements
-The Z5U capacitor is characterized by its small size and low cost, making it particularly suitable for application in decoupling circuits
-Y5V capacitor has the worst temperature characteristic, but its capacity is large, which can replace the low capacitance Aluminum electrolytic capacitor

MLCC commonly uses different media specifications such as C0G (NP0), X7R, Z5U, Y5V, etc. Different specifications have different characteristics and applications. The main difference between C0G, X7R, Z5U, and Y5V is their different filling media. Under the same volume, the capacity of capacitors composed of different filling media varies, resulting in different dielectric losses and capacity stability. Therefore, when using capacitors, different capacitors should be selected based on their different functions in the circuit.

MLCC is an abbreviation for multilayer ceramic capacitor.

According to temperature characteristics, materials, and production processes, MLCC can be divided into the following categories: NPO, COG, Y5V, Z5U, X7R, X5R, and so on.
NPO and COG have stable temperature characteristics, small capacitance value, and high price;
Y5V and Z5U have large temperature characteristics, large capacitance values, and low prices;
X7R and X5R are between the above two types.

Classified by material SIZE. It can be roughly divided into 3225, 3216, 2012, 1608, 1005, 0603, 0402. The larger the value, the wider and thicker the SIZE. Currently, the most commonly used is 3225, and the minimum is 0402.

Currently, chip multilayer ceramic capacitor (MLCC) materials widely used in portable products can be divided into two major categories based on temperature characteristics: BME based C0G products and LOW ESR selected X7R (X5R) products.

The capacity of the C0G type MLCC is mostly below 1000pF, and the main performance index related to low power consumption of this type of capacitor is the loss angle tangent value tan δ (DF)。 The DF value range of C0G products for traditional noble metal electrodes (NME) is (2.0 to 8.0) × 10-4, while the DF value range of C0G products for innovative base metal electrodes (BMEs) is (1.0 to 2.5) × 10-4, about (31-50)% of the former. This type of product has significant low power consumption characteristics in GSM, CDMA, cordless phones, Bluetooth, and GPS systems with T/R module circuits.

The capacity of the X7R (X5R) type MLCC is mainly concentrated above 1000 pF, and the main performance index related to the low power consumption of this type of capacitor is the equivalent series resistance (ESR).

In the use of chip MLCC, many customers will encounter capacitor cracking, short circuit, burning and other phenomena, so how to deal with these phenomena?
First of all, we need to know the causes of these phenomena.

A. Crack (refers to the crack on the capacitor that causes the product to fail to work normally). This phenomenon is generally caused by low resistance.
The reasons are as follows.

1. PCB is mostly open circuit after external force.
2. If the non-capacitor body is impacted by external force, it may have short circuit or low resistance.
3. Too high applied stress voltage will lead to MLCC capacitor failure, generally short circuit or low resistance, but this kind of phenomenon should not be much in the case of sufficient allowance.

In this case, it is generally necessary to check whether the product will be vibrated or shaken when working, and then check whether the product capacity meets the requirements.
B. Short circuit burn out (refers to the damage of the capacitor in the PCB board, resulting in the failure of the product to continue to work).

The reasons for this phenomenon are as follows.
1. The model of capacitor package is not big enough;
2. Insufficient reserved allowance;
3. The voltage withstand is too low or the product current is too high.

If this happens, we need to replace the chip capacitor model and check the specific reason. Then choose to replace the chip capacitor capacity or model.
If you can't find a suitable model to replace, you can use the capacitors in parallel or series to solve the problem.
