SMD resistor

Friday, 28. January 2011 9:29

Chip resistors are constructed with use of the thick film technique on a ceramic substrate.They have metallic areas on the narrow ends of the chip, which allows soldering. The resistive path is covered with a protective glaze. Chip resistors could be soldered with all common soldering techniques: reflow, wave and solder iron.SMD resistors are available as a chip or as a MELF.The most popular resistors case forms are 1206 and 0805.The rectangular chip forms are the same as for capacitors and could be processed by layout design, assembling and repair with the same rules.

Toggle switch

Wednesday, 26. January 2011 9:12

A switch is an electrical component that can break an electrical circuit,interrupting the current or diverting it from one conductor to another.A toggle switch is a class of electrical switches that are manually actuated by a mechanical lever, handle, or rocking mechanism.Toggle switches are available in many different styles and sizes,and are used in countless applications.Many are designed to provide, e.g.,the simultaneous actuation of multiple sets of electrical contacts,or the control of large amounts of electric current or mains voltages.

double-sided PCB

Monday, 24. January 2011 8:55

Double sided boards are made with a substrate of non conductive material, over which a layer of copper is placed on top of it, and in the case of double sided boards, the copper is also layered on the bottom side of the substrate.Double sided pcb boards are a common tool in both production and prototype circuits. They allow a higher density in components and make laying of tracks an easier process, this is because you have a whole extra layer where you can add tracks to connect the components, freeing space on the other to place the components closer together or add extra connections for IC with high pin counts.

10mm zinc oxide varistor

Thursday, 20. January 2011 9:06

For 10mm zinc oxide varistor,it has wide operating voltage which is from 18V~1800V and the withstanding surge current is 500~3500A.Zinc oxide varistors are a polycrystalline structured material consisting of semiconducting zinc oxide crystals and a second phase located at the boundaries of the crystals.Zinc oxide varistor consists of a large number of boundaries (several millions) forming a series-parallel network of resistors and capacitors, appearing somewhat like a multijunction semiconductor.Zinc oxide varistor is used for transistor,Diode, IC, Thyristor or diac semiconductor protection.

FET

Friday, 14. January 2011 5:47

The field-effect transistor (FET) relies on an electric field to control the shape and hence the conductivity of a channel of one type of charge carrier in a semiconductor material. FETs are sometimes called unipolar transistors to contrast their single-carrier-type operation with the dual-carrier-type operation of bipolar (junction) transistors (BJT). all FETs also have a fourth terminal called the body, base, bulk, or substrate. The FET can be constructed from a number of semiconductors, silicon being by far the most common. Most FETs are made with conventional bulk semiconductor processing techniques, using the single crystal semiconductor wafer as the active region, or channel.

Diode

Thursday, 13. January 2011 7:53

In electronics, a diode is a two-terminal electronic component that conducts electric current in only one direction.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. Thus, the diode can be thought of as an electronic version of a check valve. Ordinary diodes can be split into two types: Signal diodes which pass small currents of 100mA or less and Rectifier diodes which can pass large currents. In addition there are LEDs and Zener diodes.
