   As a company committed to corporate social responsibility, Kingtronics International is always eager to hear the stories of those we support through our sponsorship programs. Recently, we received a heartfelt letter from one of the students we sponsor in the Guangxi Zhuang Autonomous Region in China, and his words truly resonated with us.

In his letter, a senior high student expressed his sincere gratitude for the financial support provided by Kingtronics International. He shared how, during the winter break, he was finally able to experience a sense of relaxation and relief from the pressures of his studies. Instead of spending his days solely focused on academic pursuits, he had the opportunity to spend quality time with his family, particularly his beloved grandmother.

Despite the sweltering heat of the midday sun, this young student found immense joy in simple activities like digging sweet potatoes with his grandmother and cooking home-cooked meals together. It was a chance to connect with his roots, embrace his cultural heritage, and strengthen the bonds of family love.

Reading his words, we were deeply moved by the profound impact that our sponsorship had on his life. Beyond just providing financial assistance, we had helped create moments of happiness, warmth, and togetherness that would be cherished for a lifetime. As we reflect on his story, we are inspired to redouble our efforts in our corporate social responsibility initiatives, fueled by the belief that together, we can create a brighter, more compassionate world for all.

Sincerely,
The Kingtronics International Team

Kingtronics Angel Charity Social Activity in 2024 Spring

Welcome to send email to us at info@kingtronics.com We believe your participation will make this activity be more better!

 

With more than 30 years experience as leading manufacturer, Kingtronics has been always committed ourselves to improve our technique and revolutionizing our products to satisfy the market’s rapid changing demand.

With development of the surface mount welding technology, Kingtronics has developed reflow soldering newly to replace traditional wave soldering to fit small size trimpot like RKT-3269 and RKT-3361.The reflow soldering is more environmental friendly due to the soldering material not including lead. Additionally, it has more accurate control in the soldering process to increase the quality of trimpot.


Here are the product features for RKT-3269 and RKT-3361.

Kingtronics new technique “Reflow Soldering” for SMD Trimming Potentiometer (Trimpot)

Diode is a dual electrode electronic component with asymmetric conductivity. When conducting forward, there is an infinitesimal resistance between its two electrodes (anode and cathode), while in reverse, there is an infinitesimal resistance, meaning that current is only allowed to flow through the diode in a single direction.
In 1874, German physicist Karl Braun discovered the rectification ability of crystals. Therefore, the first generation diode developed in 1906, the "cat whisker diode," was made from mineral crystals such as galena. Early diodes also included vacuum tubes, which had two electrodes, an anode, and a thermal cathode. After the discovery of semiconductor performance, diodes became the world's first semiconductor device. Nowadays, most diodes are produced using silicon, and other semiconductor materials such as selenium or germanium are sometimes also used. The most common structure currently is a semiconductor performance junction chip connected to two electrical terminals through a PN junction.

Function
A diode has two terminals, anode and cathode, and current can only flow in a single direction. That is to say, current can flow from the anode to the cathode, but not from the cathode to the anode. The application of the unidirectional characteristic possessed by diodes is commonly referred to as the "rectification" function. In a vacuum tube, the voltage applied between the electrodes can allow hot electrons to travel from the cathode to the anode, thus having a rectifying effect. The conversion of alternating current to direct current, including the modulation of radio signals by radio receivers, is achieved through rectification.

Due to its characteristic of blocking forward and reverse flow, diodes can be thought of as electronic versions of check valves. However, in reality, diodes do not exhibit such perfect switching performance, but rather exhibit complex nonlinear electronic characteristics determined by specific types of diode technology. Generally speaking, the diode will only start working when the threshold voltage is reached in the forward direction (this state is called forward bias). The voltage drop at both ends of a forward biased diode is only slightly related to the current and is a function of temperature. Therefore, this feature can be used for temperature sensors or reference voltages.

The nonlinear current voltage characteristics of semiconductor diodes can be changed by selecting different semiconductor materials and doping different impurities to form impurity semiconductors. In addition to being used as a switch, diodes with changed characteristics also have many other functions, such as adjusting voltage (Zener diodes), limiting high voltage to protect circuits (avalanche diodes), radio tuning (varactor diodes), generating radio frequency oscillations (tunnel diodes, Gunn diodes, IMPATT diodes), and generating light (light-emitting diodes).

In semiconductor diodes, there are types that utilize the PN junction effect of P-type and N-type semiconductor interfaces, as well as the Schottky effect generated by metal semiconductor bonding to achieve rectification. If it is a PN junction diode, it is the anode on the P-type side and the cathode on the N-type side.

 Kingtronics Introduction of Diodes

 Aluminum electrolytic and solid polymers, both have advantages and disadvantages when comparing to one another. Designers need to be aware of these differences when determining which capacitor type is best suited for use in their application.

The most notable difference between aluminum electrolytics and polymers is their electrolyte. Aluminum electrolytics have a liquid electrolyte while polymers have a solid electrolyte. These differences play a major role in the characteristics of each type of capacitor.

The solid polymer electrolyte gives the polymer capacitors advantageous characteristics over liquid aluminum electrolytic capacitors.

The advantages are as follows:
o Lower ESR at high frequency
o Lower D.F. / tan δ
o Higher ripple current ratings
o Stability over temperature
o Wider operating frequency range
o Long life
