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.

The steady-state and dynamic reliability of a tantalum capacitor are influenced by several factors under the control of the circuit design engineer. These factors are voltage derating, ripple current and voltage conditions, maximum operating temperature and circuit impedance. Tantalum capacitors possess very low electrical leakage (high leakage resistance), and will retain a charge for a long duration. They are tolerant of hot operating environments up to 125 °C, unlike standard aluminum electrolytic capacitors. Tantalum capacitors are relatively expensive, particularly the military grades. They are not particularly tolerant of heavy charge and discharge currents, particularly those of a repetitive nature, and their effective series resistance (ESR) can be high when compared to ceramics or aluminum electrolytics.

Zener diodes

26 Nov 2010

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.

Crystal Introduction

25 Nov 2010

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.

Function of diode

23 Nov 2010

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).

Our Diodes

22 Nov 2010

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.

What's the Quartz?

18 Nov 2010

Quartz  is the second most abundant mineral in the Earth's continental crust, after feldspar. It is made up of a continuous framework of SiO4 silicon–oxygen tetrahedra , with each oxygen being shared between two tetrahedra , giving an overall formula SiO2.

There are many different varieties of quartz, several of which are semi-precious gemstones. Especially in Europe and the Middle East, varieties of quartz have been since antiquity the most commonly used minerals in the making of jewelry and hardstone carvings.

Quartz can use in this luxury goods ,but also use in electrical products. If you can not believe , please visit our website www.kingtronics.com . You will find our Quartz Crystal is very popular in the market right now!

The 1N400X diodes are a popular 1.0 amp general purpose rectifier family, commonly used in AC adapters for common household appliances. Blocking voltage varies from 50-1000V. Comes in an axial-lead DO-41 plastic package.

Our Kingtronics has variety of Diodes & Rectifiers ,also IN4001-IN4007 are very popular in the word market ,we also sell well  M7 and other Diode & Rectifiers in our website www.kingtronics.com ,Welcome you to visit and give us your mind if you are interested in our Diode & Rectifiers.
