Most people know BOURNS can produce 3540S, 3590 Multiturn Precision Potentiometer,but you also know they are with very high the price tag. Shrug !

Well, Kingtronics produce full range of trimming potentiometers under our company brand name " Kt" .
We are glad that 3540S, 3590 are our strong products among them with reasonable price and superior quality.
Free samples are on hand now, please contact with us for sample evaluation.

Usually we know crystals are referring to Quartz Crystal Resonator and Crystal Oscillator , so what is the basic difference of these two types of crystals?
Today, we would like to distinguish them from their structure. Please follow us with below blog.

Active Crystal Oscillator : Metal Lid, Quartz Blank, Coated Electrode, IC, Ceramic Base, Solder Pads.
Passive Quartz Crystal Resonator : Metal Lid, Quartz Blank, Coated Electrode, Ceramic Base, Solder Pads.

So do you find the difference ? The main point is that Crystal Oscillator is with an IC part . We are sure that you will have a better idea after you read below picture.

When you order Crystal Oscillator, you have to at least keep 5 essential aspects.
Package Type,  Frequency, Suply Voltage, Frequency Tolerance,Operating Temperature

Examples : 
QKT-OSC3225, 32.768KHz,  1.8V, +/-10ppm, -10~+60
QKT-OSC5032, 32.768KHz,  3.3V, +/-20ppm, -20~+70
QKT-OSC7050, 32.768KHz,  5.0V, +/-20ppm, -40~+85

Free samples are available and welcome your enquiry and test our samples.

About

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.
