Kingtronics Blog

Kt Kingtronics established in 1995, we are a professional manufacturer, producing Trimming Potentiometers, Aluminum Electrolytic Capacitors(Snap-in, SMD, Radial Type), Dipped and SMD Tantalum Capacitors, Radial and Axial Multilayer Ceramic Capacitors, Diodes & Transistors, Bridge Rectifiers and so on.

Here, we would like to share you some knowledge of Electrical Parameters:
C, the capacitance of the capacitor;
DF, the dissipation factor, is a measure of the losses in the capacitor.
RESR, the equivalent series resistance, which summarizes all ohmic losses of the capacitor, usually abbreviated as "ESR".
LESL, the equivalent series inductance, which is the effective self-inductance of the capacitor, usually abbreviated as "ESL".
Rleakage, the resistance that represents the leakage current.

Kt Kingtronics can supply you high quality products on favorable terms and conditions. Warmly welcome to get further information about us.

Chinese Spring Festival is coming, but there will be our exciting company annual symposium before that.

It would be a great gathering of dancing, singing, short sketch, good food and so on. The best programs will be encouraged with award.

The annual symposium is a time for relaxing, preforming more talent except for work, enhancing the team spirit...

Let's look forward to the big party !  ~O(∩_∩)O~ 

A potentiometer is an adjustable resistor, and it is constructed using resistive element comprising an arc of a circle and a sliding contact (wiper) travelling over that arc. Trimming potentiometers are Kingtronics' first products. Good quality and free samples are available for quality test.

Kingtronics trimming potentiometers perform a variety of circuit adjustments in all types of electronic equipment. Below are some Kt Kingtronics products of Trimming Potentiometers.

RKT-3006 3/4" (19 mm) Rectangular Trimming Potentiometer
RKT-3266 1/4" (6 mm) Square Trimming Potentiometer
RKT-3269 SMD Square Trimming Potentiometer
RKT-3329 1/4" (6 mm) Round Trimming Potentiometer
RKT-3309 9 mm Through-Hole Cermet Consumer Trimming Potentiometer
RKT-3540S Precision Potentiometer (Multiturn)

Welcome to check our full trimming potentiometers products and please let us know your demands, we will give our best offer to you.

"1" first, of course, is will be in good spirits
Open my eyes at that moment, clear day. Insist on getting up early will go to bed early, sleep sleep 11 points to 6 points with 1 o'clock to 8 points, felt totally different, tired during the day to sleep late recovery, you should try or not.

"2" time really is more
Insist on getting up early feeling is, is available every day seem longer than those who don't get up early, because early in the morning can be many things, higher efficiency. Working days can go swimming, rest day reading shopping dog cooking, and then look at my watch, was less than 9 points.
Early every day 12 benefits
Have time to read is important, want to know something, reading in the morning, a new year n skills, life is not virtual wood.

"3" have yourself breakfast
Do whatever I wanted to eat, Instagram inside on the big breakfast, you can do it yourself, there is time. Even if he does not do, just opened the breakfast ingredients fresh, love eat slowly without worry, aunt can't wait, feel good buns stuffed a little bit more.

"4" no crowded bus
Go by the first train early, no one with your seat, and no traffic jams.

"5" enjoy the beauty of others fail to see
At 6 o'clock in the morning and 8, are two of the world. You'll see the Sun, the sun shines on you, full of positive energy. You will see how the vendors set up their stalls, heard sanitation Boyle sing ... ...

"6" relieve anxiety
"The day" time stretch, feeling better than others for 2 hours, is not the time to catching up with you, but you're directing your time, not anxiety right away. Schedule normal, time went to sleep, had time to work tomorrow morning.

We can not control life, but can control our step, enjoy your morning.

All of them do a great job, increasing business and helping us promote, thanks a lot for all of your great business support on us !

Dear clients, it is the last week for September, 2016. Wish you all good luck and happiness in the coming October! O(∩_∩)O~

We are wondering if you have new order plans for Kingtronics before our National Day(1st Oct). Although we sales only rest on 1st-2nd Oct., our production department will have one week (1st-7th Oct) holiday for National Day! Kindly remind that they will be extremely busy after holiday and the lead time for the orders which confirmed after 1st Oct may be longer than before. Thus, I strongly suggest you can confirm order within this week, so that we can help arrange the production before holiday and proceed lead time for you. 

Welcome to share us your order request early! Thanks! 

Kt Kingtronics has been keen to some charity social activities. In 2016 Autumn, we will keep to organize an Angel Charity Social Activity, donating a part of funds to help some children in school at Guilin province. 

The funds are collected from each of Kingtronics team members. As the saying goes “You may be more happy than princes, if you will be more virtuous.” We help them at much as we can, even a small help, children will feel our love.

If you want to join our meaningful activity, welcome to send email to us at info@kingtronics.com. We believe your participation will make this activity be more better!

Selection Criteria
The initial considerations for trimmer type selection are:
A. Resolution of adjustment
B. Setability and time to set
C. Physical and environmental conditions
D. Stability of setting required
E. Circuit packaging requirements

D. Stability of Setting
It is highly desirable that once the trimmer has been set, it should remain at that setting independent of time, operating temperature changes, vibration, shock and humidity. This property of stability is largely a factor of the compatibility of the materials at the moving contact interface and the thermal matching of the elements of the trimmer structure. BI uses noble metals in both the wire brush contact and the cermet element. These materials are relatively soft, highly compatible and provide an excellent, low resistance, non-corroding interface. The contact drive structure and materials are chosen for their stability and compatibility. The high contact forces utilized at the brush/element interface reduce susceptibility to shock and vibration.

The circuit designer can contribute significantly to short term operating and long term stability by mounting the trimmer away from high thermal gradients, hot spots and sources of excessive vibration.

E. Circuit Packaging
BI manufactures trimmers in a variety of package styles and sizes. The chances are excellent that stock models are locally available that will fit your requirements. Models include both pin style and surface mount single and multiturn configurations. Special electrical and mechanical features are available for specific customer applications. Call your local representative or the factory direct for information on special packaging.

C. Physical and Environmental Issues

1. Physical considerations in trimmer selection
• Case style desired
• Top or side adjust
• Pin style required
• Mechanical support required
• Board height requirements

2. Assembly process considerations
BI offers a variety of trimmer models that are sealed to help protect against moisture and board washing processes.
•Open vs. Sealed
• Max time/temperature exposure 

3. Environmental operating considerations
• Operating temperature range
• Resistance temperature coefficient
• Vibration and shock tolerance 

4. Human operating conditions When you complete your design, be careful to consider the tortures that clever human beings with a screwdriver in hand can impose on trimmers. For example, while a trimmer configuration mounted on edge might be a board space saver, a trimmer that mounts flat on the board may be more resistant to abuse by a heavy handed technician making adjustments through a hole in the chassis.

D. Stability of setting required
E. Circuit packaging requirements

B. Setability and Time to Set
The enemies of setability are poor resolution, mechanical backlash and high CRV. BI has addressed these problems in the design of trimmer models. BI’s smooth cermet materials, precious metal split brush contacts and teflon rotors work together to provide outstanding setability.

“Time to set” tests show the following:
