Thyristors – the choice electronic component for supplying power to circuits.

Posted on: September 23rd, 2011 by admin

buy surplus thyristors

If your electronic component needs include dealing with large sources of power, you may be in the market for thyristors. Also known as silicon controlled rectifiers (SCR), a thyristor is a four-layer semiconductor that is built to handle large amounts of power. The thyristor’s specialty is controlling power circuits. The thryristor electronic parts can be turned off or on, but typically can only be turned off by switching the direction of the current.  In addition to being turned off and on, thyristors can allow the amount of power to be controlled by adjusting the angle of the current. A simple example of this type of use is the dimmer on a light switch.

The idea for the thyristor was conceived in the 1950’s, by one of the creators of the transistor, but it didn’t gain popularity until a decade later when it was brought to the general consumer market by General Electric.  Thyristors soon became the choice electronic components to buy for supplying power circuits.

In the early 1970’s the electronic parts were even being used in color televisions to help stabilize power their supplies. Thyristors also have a long history of use in the motion picture industry and theaters where they replaced older technology.

Thyristors work differently from other electronic components as no current actually flows across the device. When a power supply is connected to the device a small amount flows into the gate and the thyristor fires and conducts. The thyristor then remains conducting until the power supply is removed. .

The electronic components are generally made from silicon because it can handle high voltage and power currents. Silicon is also known for its thermal properties. Silicon is also affordable and can be bought and sold cheaply for manufacturing use.

Analogue electronics often make use of thyristor technology. Thyristor circuits are widely used and available at affordable prices. IC Plus is a certified electronic component distributor and has access to stocks of newer and obsolete surplus thyristor components. The company sells surplus thyristors made from all kinds of manufacturers.

Whether you are looking for a Gate Turn-Off Thyristors (GTO), Reverse Conducting Thyristors (RCT), a Base Resistance Controlled Thyristor or a Static Induction Thyristor (SITh), chances are, IC Plus has the surplus thyristors components you are searching for at an affordable price.

Resistors and Capacitors, Electrical Component

Posted on: July 26th, 2011 by admin

A resistor is a passive two-terminal electronic component which is used to control voltage by restricting the flow of current in a circuit. Resistors may also protect sensitive electrical components from exploding or blowing due to excessive voltage. Higher resistance means that there will be less current in a circuit. Resistors may either look microchips, or they may be a wire with a small, bead-like colored cylinder of resisting material around it. They are common elements of electronic circuits and electrical networks and are found in almost all electronic equipment. They can be implemented within integrated circuits (microchips), especially in analog devices, and also may be integrated into printed and hybrid circuits.

Resistors can be joined in different combinations in order to complete a circuit. They may be linked in a series, where the resistors are connected on after the other, or that may be parallel, where the resistors are connected over one another. When linked in a series, the current through all of the resistors will be the same, but the voltage across each one will be in proportion to its resistance. When in a parallel configuration, resistors are all subject to the same voltage, but the currents through each one will increase.

There are many varieties of resistors available. Each has a different rating to indicate its resistance to electricity. If a resistor is met with too much power, it may break or its function may become erratic. The bead-like style of resistor has a series of colored bands around it to indicate its rating. Other types of larger resistors are marked numerically, however most modern resistors are so small that marking them is impractical. A resistor’s color may also indicate its rating.

Resistors may be made out of many different materials. In the past, resistors were made from solid carbon, but this type is rare now because it did not fare well with air moisture and can be too expensive to make. Many modern resistors do still utilize carbon as a film. Other modern resistors are made from metal or wire. Newer resistors are also much better at handling air moisture and high heat from electricity. In a properly designed circuit, the failure rate of resistors is much lower than that of other electronic components like electrolyte capacitors and semiconductors. Resistors most often become damaged due to overheating when they receive too much power. This problem can be avoided by ensuring that the resistor is chosen and installed properly.
