Hello my dear friend,
 
Wish you enjoy a nice weekend. :-)
 
This time our starring role is Trimming potentiometer, which is a kind of variable resistor and called trimmer and preset. It's meant to be set correctly when installed in some device, and never seen or adjusted by the device's user. It can be used in many fields such as inspection machine, remote control, amplifier, controler, smoke detector...
 
Are you manufacturer in these fields or distributor for electronic components? Do you have demand for trimming potentiometer? Could you pls send me your request and I will reply you soon.
 
We Kingtronics is one of the oldest factories for trimming potentiometers in China. Our Trimming Potentiometer is ISO &SGS certified. With more than 20 years' development, our trimmer sell to many famous distributors, and can cross to many famous brands like Bourns, Murata and Vishay. We can offer you very good price and 3-4 weeks delivery. 
 
Trimming potentiometer: 3006 3386 3266 3296 3329 C3305 065
 
Could you pls help us promote to your clients or friends who use or buy them? Sending me your inquiry and let me quote best price for you, ok?
 
Look forward to your response and pls email to info@kingtronics.com

I would be very appreciated to receive your capacitors inquiry. Thanks for your time on this email.

Also please visit our website and help us promote our most strong diode M7, LL4148, SM4007, BZV55C.

This week our topic is Zener Diode. Do you know what is zener diode? What's the application? Here I will have a detailed explanation for you.

Zener diodes are a special type of semiconductor diode--devices that allow current to flow in one direction only, which also allow current to flow in the opposite direction, but only when exposed to enough voltage. And while that sounds a bit esoteric, they're actually among the handiest components ever to cross an engineer's bench, providing great solutions to a number of common needs in circuit design.

It can be widely used on protector and receiver. Do you need them in your production? or do you have any friends or customers who use/buy them? Kindly pls note and help to promote.

We can offer you very good prices and fast delivery once you have inquiry for us.

Look forward to hearing from you and pls email to info@kingtronics.com.
