According to IEC 60384-14, capacitors are divided into X capacitors and Y capacitors
1. X capacitance refers to the capacitor between L and N
2. Y capacitance refers to the capacitor between L-G/N-G. (L=Line, N=Neutral, G=Ground)

The capacitance of X is divided into X1, X2 and X3. The main differences are as follows:
1. X1 high voltage resistance is greater than 2.5kV, less than or equal to 4kV
2. High voltage resistance of X2 is less than or equal to 2.5kV
3. High voltage resistance of X3 is less than or equal to 1.2kV

The capacitance of Y is further divided into Y1, Y2, Y3 and Y4. The main differences are as follows:
1. Y1 high voltage resistance is greater than 8 kV;
2. Y2 resistance to high voltage greater than 5 kV;
3. Y3 resistant to high pressure N/A;
4. Y4 high voltage resistance is greater than 2.5kV

These capacitors are based around the use of a polyester dielectric. As with any capacitor, polyester capacitors have their own characteristics. This means that they are suited to some applications more than others. Mylar capacitors have low levels of moisture absorption.

Mylar is an excellent electrical insulating material, with a high breakdown voltage, very high DC resistance, DC blocking and  Ultra-low ESR.

It is estimated that the output value of quartz components in 2019 and 2020 will be 34.0 and 3.52 billion US dollars, respectively.
It continues to grow steadily, and since it is mostly a customized product, there are no supply and demand gaps and significant price increases; quartz components continue to benefit from the trend of miniaturization, and most of the components are customized products, and customer demand is stable.

In 2020, it is estimated that due to the increase in demand for 5G mobile phones and Netcom equipment, the industry trend is expected to continue to grow steadily.
The production of quartz components was reduced in 1H19 due to Japanese manufacturers, and the market supply decreased.
What's more, it is estimated that some components will be tight in 2H20, which will cause a new wave of component price increases.

How about turning to Kingtronics, our Quartz Crystals can support you favorable price and stable L/T 3-5 weeks with RoHS certified.  Remain at your service!

Principle of Trimmer Potentiomerets

A fixed resistor with a mechanism to change resistance construct a trimmer potentiometers. The principle is with the changing of resistive element length according a wiper sliding, the resistance will be changed. Use this method, with same sectional area, the resistance can be changed relative to resistive element length, and products can be manufactured in low cost.

            R: Resistance [Ω] 
            ρ: Resistivity [Ω/m] 
            L: Resistive element length [m] 
            S: Resistive element sectional area [m2]

• The position of contact point decide the length of resistive element.
  Resistance between No.1 and No.2 (R12) will become higher if contact point become closer to No.3.
• For easy introduction, we drew the resistive element like a rectangular solid. Actually, almost resistive element is round shape 
  (U - shaped) .So the track of wiper is circle, and resistance is decide by the angle of wiper. 

Change in resistance of Trimmer Potentiometers

There is the relationship between wiper position (angle) and resistance in below figure.

The output wave is besed on below conditions.
Resistive element is round shape (U - shaped) /Single - turn/No whirl - stop.

Feature of Trimmer Potentiometers

By using trimmer potentiometers, it is no problem to set surrounding circuit constant roughly.
Would you please use trimmer potentiometers if it is difficult to decided on a resistance value in your circuit. You can design your circuit roughly and quickly as the result.
