Wholesale electronic resistor supplier providing high end electronic components

Wholesale Electronic Resistor Supplier Providing High-end Electronic Components A resistor is a small or passive electronic component which is designed to provide a specific amount of resistance in the electronic circuit either to limit current through an active component or to decrease voltage in the circuit.

Resistors come in a variety of sizes, shapes, types and capacities. All resistors are not made equal. Each type of resistor has differences in typical values for resistor wattage rating, noise, tolerances, temperature coefficient, voltage coefficient, size, frequency response and reliability.

Electronic components store provide high-end quality resistors. You may purchase best electronic components as per your business requirements.

Types of resistors Resistor is the most widely used component in electronic circuits. There are different kinds of resistors available with distinct properties; some of them are mentioned in brief here.

Wire wound resistor Wire wound resistor is constructed by winding a thin metal alloy wire or wrapped around an insulting core like porcelain, cement and pressed paper. It is usually used for high current applications with low resistance and appreciable power. The wire wound resistor is commonly

used for various applications such as computers, telecommunication, audio and video equipment, current and voltage balancing.

Carbon composition resistors Carbon composition resistors are made of carbon and graphite mixed with a powdered insulting material. Metal caps with tinned copper wire which is known as axial leads are attached to each end of the carbon resistance element. These are used in many applications which include current limiting, surge or discharge protection, high voltage power supplies, high power or strobe lighting and welding. These resistors are reliable and cost-effective compared to other resistors.

Carbon film resistors Carbon-film resistors are less sensitive to temperature changes, create less noise and have tighter tolerances as compared to carbon composition resistors. They are made by depositing a very thin layer of carbon on the ceramic rod and protected by a flameproof jacket as this kind of resistor will burn if overloaded sufficiently. It is typically used in high voltage and temperature applications.

Metal film resistors Metal film resistors are less sensitive to temperature changes, create less noise and have tight tolerances. It is made by placing a film of metal like nickel alloy onto a ceramic rod. They are used in active filters and bridge circuits.

Thermistors A thermistor is a temperature sensitive resistor which is often used as a temperature senor. It is a kind of resistor whose resistance changes significantly with change in temperature.

Thermistors are commonly used in electronic circuits where temperature measurement, control and compensation are needed.

Fusible resistors Fusible resistors consist of both functions – as being resistor in normal condition and changed into fuse when abnormal current flows to protect machines and equipment. They are small in size and apt for protecting circuit boards. They have low temperature coefficient and excellent stability.
