Trimmers come in a variety of sizes and levels of precision; for example, multi-turn trim potentiometers exist, in which it takes several turns of the adjustment screw to reach the end value, allowing for very high degrees of accuracy. Our Kingtronics has many types of Trimming Potentiometers ,for example RKT-3006  RKT-3296 and so on ,these products is for our KT mark ,you can set your heart at rest ,we can guarantee our quality .So if you are interested in our Trimming Potentionmeters, welcome to visit our website:  If you have any questions please contact us, we can try our best to meet your requirements.

A typical surge arrester consists of disks of zinc oxide material sized in cross-sectional area to provide desired energy discharge capability, and in axial length proportional to the voltage capability. The disks are then placed in porcelain enclosures to provide physical support and heat removal, and sealed for isolation from contamination in the electrical environment.

Kingtronics specialized in 2-Electrode Surge Arresters.We have many different types of Surge Arresters , please send your enquiry for our KT mark SKT-2R-230A2.

Kingtronics sales had sucessful exhibition at HK fair, our blue nice booth might leave you deeply impression, right? Please visit our blog to see our photos at HK fair:

Do you buy 3-Electrode Surge Arresters and 2-Electrode Surge Arresters . Kingtronics produce Surge Arrester in our factory, lead time is short, prices are as competitive as our diode rectifier M7, everybody know Kingtronics rectifier M7, hehe.. More important, this products we don't have much competitors. Please send us inquiry for diode and surge arresters.

Our surge arresters can cross to Nisshin Electric and Epcos:

  • SR3YP Series(ITU-T Standard): 3-Electrode Arresters
  • SRYH Series(ITU-T Standard): 2-Electrode Arresters

BTW, our website is updated, you can download part list of diode, cross reference of capacitors, Trimming Potentiometer, and SGS certifications from our website.

The largest application for tantalum is in the electronics capacitor industry, totaling approximately 68 percent of global demand, as its high melting point, strength, ductility, reliability, resistance to corrosion and thermal conductivity make the metal an efficient, reliable and environmentally versatile component for capacitors.  These tantalum capacitors are commonly found in such products as wireless devices, LCD monitors, DVD players, cell phones, personal computers, digital cameras, gaming platforms, telephone switch boards and computer networks because of unequaled capacity to store and release electrical charges.

Now, Kingtronics lead time are better than AVX, Kemet, Vishay...Welcome to send us inquiry!


Multilayer Ceramic Capacitor(MLCC) is an electronic part that temporarily stores an electrinical charge and the most prevalent type of capacitor today.New technologies have enabled the MLCC manufacturers to follow the trend dictated by smaller and smaller electronic devices such as Cellular telephone,Computers,DSC,DVC,GPS.

Besides chip mlcc capacitor, Kingtronics radial mlcc capacitor (mono capacitor) is unbeatable in the market - Good price, High quality and Short lead time.

From Oct 13th - 16th, Kingtronics had successful exhibition in HK ElectronicsAsia2010. We met many old customers and new customers.

Our tantalum capacitors,Trimming Potentiometer and diode rectifier have very good feedback.

Imagine a perfectly innocent quartz crystal that has grown to considerable size. It is lying there, at the bottom of a shallow sea, when a meterorite rudely invites itself to crash into the Earth's surface with considerable noise, pressure, heat.

There is so much pressure and heat, in fact, that only a meteorite or asteroid can cause what happens next: the quartz is shocked!

Shocked quartz is quartz that has been subjected to an event that cannot happen from normal Earthly causes and which has had its very planar structure changed. The only two known causes of shocked quartz are nuclear explosions such as the Alamo field and the incredible impact forces of meteorites or ancient asteroids. The Pleistocene/Holcene astroid impact is one of the biggest culprits. This impact occured in North America about 12,000 years ago, creating a type of brecciated rock called impact breccia.

One aspect of the impact that creates shocked quartz, however, is that high heat is not involved, or the quartz would revert to its original structure. In some shocked quartz samples, the quartz resumed its normal growth pattern within a section of planar deformities.

Brecciated rock is like gravel that is cemented together in a finely grained matrix that may or may not have the same composition as the gravel. Impact breccia is formed through extra terrestial or nuclear impact and is generally found in or around impact craters.

Quartz crystals are said to be the second most abundant substance in the Earth's crust. They are composed of silicon-oxygen tetrahedra where one oxygen molecule is shared between each two tetrahedron. The crystals grow perpetually in a six sided prism that terminates in a six sided pyramid.

Shocked quartz crystals contained shocked lamellae, or small fractures that create lines in the quartz that go along the planes of the crystal.  These planes can usually only be viewed under a microscope. \

But often, special microscope techniques, such as electron microscope, high resolution transmission electron microscopy (TEM), Focused Ion Beam (FIB) tomography, cross polarization, reflected light, thin slicing and polishing are required before the microscopic deformations can be seen.

Sometimes, the deformations actually can be examined as if they were "pressure gauges", with various deformities helping to identify the amount of pressure that it would have taken to create them. New methods of examining the samples are being used, with goals of gathering more information and images of smaller and younger samples.

The most famous sites for such impact craters include the Chicxulub structure on the Northern Yucatan Penninsula of Mexico, the Bavarian Town of NÖrdlingen, Arizona, India, and generally in the K-3 boundary between Cretaceous and Tertiary rocks.
