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.

Kingtronics can support you with qualified chip MLCC.
Welcome to share us your demand !

Murata is the leader of global MLCC. In end of 2020, Japanese employees of Murata Manufacturing Co., Ltd. successively diagnosed the corona virus, production lines have to be stopped.
It resulted in tight production capacity and high supply pressure, and the delivery period of some goods was extended.

Kingtronics can support MLCC with lead time around 3-5 weeks can help you alleviate this problem.

It can be speculated that the shortage of MLCC will relatively increase the demand for tantalum capacitors, such as price changes due to insufficient supply.

* Mainly due to the increasing use of MLCCs in smartphones, cameras, and automobile manufacturing, demand has been gradually increased, and supply has fallen short of demand.
Current delivery period of other manufacturers is at least 40 weeks (MLCC shortage is expected to continue till 2020).

* The market is looking for alternatives to solve the shortage of multilayer ceramic capacitors MLCC, some can be replaced by capacitors with equal ratings (such as tantalum capacitors).
The main difference between tantalum capacitors and ceramic capacitors is their performance at a certain temperature and voltage difference. In many applications, tantalum capacitors can be used to replace MLCCs, but tantalum may increase the cost of the assembly.

* Reasons affecting the price and delivery of tantalum capacitors: increased demand for national defense and aviation, fires in the tantalum mine in Brazil (occurred in March 2019), and the weakening of US dollar against CNY due to international exchange rate factors).

At present, it has been confirmed that MLCC is in short supply and some tantalum capacitors can be replaced. Therefore, the demand for tantalum capacitors has increased. If the supply is insufficient, it will cause market price changes and market supply shortages.

Ceramic capacitors are used as the dielectric ceramic, the ceramic coating on both sides of the silver layer, through low-temperature firing silver film as plates percent. 
Its shape has a chip, tube-shaped, round, etc.

The Ceramic Capacitors, as shown in below Picture, has a structure in which many dielectric layers and internal electrodes are alternately stacked and the internal electrodes are connected in parallel. 

Kingtroncis product  included surface mount capacitors from the 0402 case size to larger high voltage units (up to 4KV) for commercial and high reliability applications.

Kingtronics specializes in manufacturing MLCC multilayer ceramic capacitors. Our  LKT Series Chip MLCC Capacitors(Multilayer Ceramic Capacitors) ranges from 6.3V to 50V.

The fundamental electrical properties of multilayer ceramic capacitors are as follows:

Polarity: Multilayer ceramic capacitors are not polar, and may be used with DC voltage applied in either direction.

Rated Voltage: This term refers to the maximum con tinuous DC working voltage permissible across the entire operating temperature range. Multilayer ceramic capacitors are not extremely sensitive to voltage, and brief applications of voltage above rated will not result in immediate failure. However, reliability will be reduced by exposure to sustained voltages above rated.

Like all other practical capacitors, multilayer ceramic capacitors also have resistance and inductance. A simplified schematic for the equivalent circuit is shown in Figure 1. Other significant electrical characteristics resulting from these additional properties are as follows：

Impedance: Since the parallel resistance (Rp) normally very high, the total impedance of the capacitor is ：

The variation of a capacitor’s impedance with frequency determines its effectiveness in many applications.
