Quartz crystals have piezoelectric properties; they develop an electric potential upon the application of mechanical stress. An early use of this property of quartz crystals was in phonograph pickups. One of the most common piezoelectric uses of quartz today is as a crystal oscillator. The quartz clock is a familiar device using the mineral. The resonant frequency of a quartz crystal oscillator is changed by mechanically loading it, and this principle is used for very accurate measurements of very small mass changes in the quartz crystal microbalance and in thin-film thickness monitors.Our Kingtronics short for Kt (logo) crystals are widely used in the oversea market.

Kingtronics offers leaded quartz crystal HC49U, HC49S and SMD quartz crystal HC49SMD.

Quartz Crystals General Information

Variable resistors used as potentiometers have all three terminals connected. This arrangement is normally used to vary voltage, for example to set the switching point of a circuit with a sensor, or control the volume (loudness) in an amplifier circuit. If the terminals at the ends of the track are connected across the power supply then the wiper terminal will provide a voltage which can be varied from zero up to the maximum of the supply.

Kingtronics are potentiometers manufacturer since 1990. Trimming potentiometers are Kingtronics' first products. RKT-3006 is one of the Trimming potentiometers,It is used where very precise adjustments must be made.RKT-3006 has 3 terminal styles:3006W, 3006P, 3006Y. The screw must be turned many times (10+) to move the slider from one end of the track to the other, giving very fine control.

Tantalum electrolytic capacitors exploit the tendency of tantalum to form a protective oxide surface layer, using tantalum powder, pressed into a pellet shape, as one "plate" of the capacitor, the oxide as the dielectric, and an electrolytic solution or conductive solid as the other "plate". Because the dielectric layer can be very thin (thinner than the similar layer in, for instance, an aluminium electrolytic capacitor), a high capacitance can be achieved in a small volume. Because of the size and weight advantages, tantalum capacitors are attractive for portable telephones, personal computers, and automotive electronics.

Kingtronics short for Kt (logo) produce tantalum capacitors since 1997, include dipped tantalum capacitors (through hole capacitors), general purpose chip tantalum capacitors (surface mount) and Low-ESR chip tantalum capacitors (surface mount).We have a full instruction about Tantalum Capacitors in our website www.kingtronics.com  each series of Tantalum Capacitors have detailed PDF and other information.

Rectifiers find a use in detection of amplitude modulated radio signals. The signal may be amplified before detection, but if un-amplified, a very low voltage drop diode must be used. When using a rectifier for demodulation the capacitor and load resistance must be carefully matched. Too low a capacitance will result in the high frequency carrier passing to the output and too high will result in the capacitor just charging and staying charged.

Kingtronics’s fast recovery rectifier diodes are very popular in the overseas market, According to the rectifier’ s application , Our Kingtronics managing ordinary rectifier diodes, ultra-fast rectifier diodes. In our Kingtronics website www.kingtronics.com ,we have detailed PDF about all kinds of diodes & rectifiers.

Zener diodes are used to maintain a fixed voltage. They are designed to 'breakdown' in a reliable and non-destructive way so that they can be used in reverse to maintain a fixed voltage across their terminals.

Zener diodes can be distinguished from ordinary diodes by their code and breakdown voltage which are printed on them. Zener diode codes begin BZX... or BZY... Their breakdown voltage is printed with V in place of a decimal point, so 4V7 means 4.7V for example.

Kingtronics supplies BZV55C/ZMM55C-SERIES with Low zener impedance,Low regulation factor,Glass passivated junction,High temperature soldering guaranteed:260 C/10S at terminals. Please link http://www.kingtronics.com/pdf/BZV55C.pdf ,you will see all series of our Zener diodes.

A crystal or crystalline solid is a solid material whose constituent atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word crystal is derived from the Ancient Greek word κρύσταλλος (krustallos), meaning "rock-crystal" but also "ice", from κρύος (kruos), "icy cold, frost". The word once referred particularly to quartz, or "rock crystal".

Electronic-grade quartz crystal is single-crystal silica which has properties that make it uniquely useful for accurate frequency controls, timers, and filters in electronic circuits. These devices are utilized for a wide variety of electronic applications in communications equipment, computers, aerospace hardware, instruments for commercial use.

The most common function of a diode is to allow an electric current to pass in one direction (called the diode's forward direction) while blocking current in the opposite direction (the reverse direction). Thus, the diode can be thought of as an electronic version of a check valve. This unidirectional behavior is called rectification, and is used to convert alternating current to direct current, and to extract modulation from radio signals in radio receivers.

Different types of diode will have different function, this is depends on their voltage, temperature, and other factor. So it is very important when you check your diode, Our Kingtronics provide diode's detailed function. If you have any problems, please look for some suggestions in www.kingtronics.com.

"Mono" refers to a "monolithic" or "multilayer" capacitor. This just refers to the manufacturing process whereby the capacitor is formed by binding multiple, thin sheets of ceramic on which electrodes have been painted.

As the ceramic material technology continues to advance, more and more capacitance is realized in the same case sizes compared to previous years. Kingtronics produce and sell ceramic capacitors all types. Multilayer ceramic capacitors are available in four series in Kingtronics: AKT Series Axial Lead, Axial MLCC Capacitors(Multilayer Ceramic Capacitors), MKT Series Radial MLCC Capacitors(Multilayer Ceramic Capacitors), LKT Series Chip MLCC Capacitors(Multilayer Ceramic Capacitors) (6.3V to 50V), and HKT Series High Voltage MLCC Capacitors(Multilayer Ceramic Capacitors) (63VDC to 4000VDC).

In electronics, a diode is a two-terminal electronic component that conducts electric current in only one direction. The term usually refers to a semiconductor diode, the most common type today. This is a crystalline piece of semiconductor material connected to two electrical terminals.A vacuum tube diode (now little used except in some high-power technologies) is a vacuum tube with two electrodes: a plate and a cathode.

Kingtronics produce and sell many different kinds of diodes, general purpose diode M7, switching diodes LL4148 etc.They are widely used in LCD,TV and other fields, If you would like to check our full products list,please link here: http://www.kingtronics.com/products.html ,you can see all kinds of diode from our Kingtronics.
