MOSFETs

Posted on: October 28th, 2011 by admin

surplus MOSFETs onlineIt is the fastest growing of any silicon-based transistor technology because of its use in computer microprocessors. MOSFETs (Metal Oxide Semiconductor Field-effect Transistor) are used for amplifying or switching electronic signals.

The principles behind the MOSFET transistors go back to the early 1920’s when it was first patented. By the 1950’s, Bell Telephone tried to patent a similar transistor and found a patent already belonged to Julius Edgar Lilienfeld, whose patent covered all types of transistors. A deal was reached where Bell Labs version was given the name, Bipolar Junction Transistor, or simply Junction Transistor, and Lilienfeld’s design took the name, Field Effect Transistor. MOSFETs are used in both digital and analog technologies.

The “metal” in the name is a bit misleading as these days, as the materials used in MOSFETs are no longer aluminum, as was used up until the 1970s, but silicon.

Today, the rapid growth of the technology has made it harder to find the MOSFET you might be in the market for because as soon as they come out, they can be as quickly rendered obsolete. Luckily, there are a number of place you can go to buy MOSFETs online. Vendors buy and sell used and surplus MOSFETs, that work just as well and are more affordable than buying MOSFETS straight from the manufacturer.

Varistors

Posted on: October 21st, 2011 by admin

Much like fuses, varistors are another electronic components used to protect circuits from excessively high voltage. Varistors, also known as Voltage Dependent Resistors or VDR, are incorporated in the circuit so that they can keep excessive current from high voltages away from sensitive parts of the components.

One of the most common types of varistors is the Metal Oxide Varistor (MOV). An everyday example of MOV technology is the surge protector features on a power strip. The surge protector works by protecting electronic devices from power surges. So, if there is a surge in the amount of voltage provided, average in the United States is 120 volts, the surge protector creates a barrier, with the help of the varistor, to stop it from destroying your computer.

Varistors are also used in communications technology, like telephone lines and radio communications equipment to suppress devices. There are some things that varistors will not do, like providing protection for equipment during start-up, when there is a short circuit, or from brownouts also called voltage sags.

Semiconductors and our everyday technology

Posted on: October 14th, 2011 by admin

You may not know it, but throughout an average day, you are likely to come in contact with hundreds of semiconductors. Semiconductors are the building blocks of a myriad of today’s technology. They reside in everything we use on a daily basis, from your computer, to your cell phone, to radios. Semiconductors conduct electricity due to electron flow and are made of a variety of materials including silicon, arsenic, selenium and tellurium. The majority of commercial semiconductors manufactured are made of silicon.

Semiconductor devices are electronic components that are manufactured as single discrete devices and as integrated circuits (ICs) which are made of devices manufactured and interconnected on a single semiconductor.  There are a number of semiconductor devices out there that are classified by number of terminal devices. Two-terminal semiconductor devices are diodes, solar cells and laser diodes. Three-terminal semiconductor devices include silicon controlled rectifiers, thyristors and bipolar transistors. There are also multi-terminal devices like microprocessors and integrated circuits.

Because semiconductors are used in almost every technology that consumers now own and use, it is easier than ever to buy or sell surplus semiconductors online. Today, you can find thousands of vendors that are buying and selling used and surplus semiconductors. The majority offer you warranties on the products they buy and sell.

If you are an electronics component company looking to buy semiconductors online, consider visiting IC Plus. IC Plus is the industry leader in selling semiconductors online.

Much Ado About Fuses

Posted on: October 7th, 2011 by admin

buying surplus fusesIn the world of electronic components, the fuse is kind of like the guardian angel.  Its job is to protect the power system by preventing too much current from flowing through a circuit, which can lead to overload or failure. Anyone who’s ever overloaded their home circuit before with a hairdryer or other powerful electronic device has probably “blown a fuse.” What’s happening in that case is the fuse has interrupted the overload of power current and prevented damage and possible fire, by shutting down the system.  The fuse dates back to the mid-1800s when it was first invented. It was later patented, with the help of Thomas Edison, as part of the electronic distribution system.

 

So how does a Fuse work?

A fuse is mounted between electrical terminals and carries the current of power through a protected circuit. If the current of power is too high, the element in the fuse rises in temperature and either melts or joins with the fuse, opening the circuit. When the metal conductor opens, an electric arc is formed between the un-melted ends of the element. The arc grows until the voltage required to sustain the arc is higher than the available voltage in the circuit. Fuse elements are made of alloys with predictable characteristics like aluminum, copper, silver or zinc.

Fuses come in different voltage ratings such as 120V or 230V. The voltage rating has to be the same or larger than the open circuit voltage to work correctly. The International Electrotechnical Commission creates standards that unify a number of national standards of fuses, which help improve the interchangeability, along with the buying and selling of fuses around the world.  In North America, low-voltage fuses to 1kV AC rating are made in accordance Underwriters Laboratories (UL).

Fuse Uses

There are a large array of fuses out there. Thermal fuses are the kind most often found in consumer products like hair dryers, electronic devices and even coffee makers. The thermal fuses are non-resettable devices that cannot be used again once they are “blown”.

Resettable fuses make use of a thermoplastic conductive element that is self-resetting. When the power current is removed, the device will cool and go back to low resistance. These types of resetting fuses are mostly used in computer components so that if a mouse or keyboard shorts, it doesn’t affect the motherboard. Resettable fuses are also often used in the nuclear and aerospace industry.
