Every country has its own national day which stands for the beginning of nation, so the National Day is very important for a country to celebrate.

The National Day of the People's Republic of China is celebrated every year on October 1. It is a public holiday in China and normally we have holidays from Oct 1st to Oct 7th. 
During this period, a variety of government-organized festivities such as fireworks and concerts are in full swing. We will also visit families and friends for holiday gathering.
Public places, such as Tiananmen Square in Beijing, are decorated in a festive theme. Portraits of revered leaders, such as Mao Zedong, are publicly displayed.
What a great day for all Chinese people around the world.  

Trimmer potentiometers and preset resistors are small variable resistors which are used in circuits for tuning and (re)calibration.

Types of Trimming Potentiometer

Several different versions of trimmer are available, using different mounting methods (through hole, smd) and adjusting orientations (top, side) as well as single and multi-turn variation.

1》Open, carbon track
2》Enclosed, side adjust
3》Enclosed, SMD

Single turn

Single turn trimmers/presets are very common and used where a resolution of one turn is sufficient. They are the most cost effective variable resistors available.

Multi turn

For higher adjustment resolutions, multi-turn Trimming Potentiometers are used. The amount of turns varies between roughly 5-25, but 5, 12 or 25 turns are quite common. They are often constructed using a worm-gear (rotary track) or (linear track) mechanism to achieve the high resolution. Because of their more complex construction and manufacturing, they are more costly than single turn preset resistors. The lead screw packages can have a higher power rating because of their increased surface area.

Trimming potentiometer symbols

The following IEC symbols are used for trimmers and preset resistors. Although this are the official symbols for occasionally adjusted resistors, the standard symbols for a potentiometer or rheostat are often used.

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval. Please visit our Products page, you could please download all our PDF datasheet and find cross reference for our Trimming Potentiometer and capacitors.
