Electrical Components Manufacturers and Companies

Electrical components, also commonly referred to as electronic components, are parts that are capable of controlling or modifying voltages or currents without mechanical or other non-electrical means. The two main categories of electrical components are active components, such as transistors and integrated circuits, and passive components, such as resistors and capacitors. The main difference between the two types of electric components is that while active electrical components require electricity to enable operation, passive electrical components do not. Since both types are used in such a wide range of applications, electronic component suppliers are essential to industries such as: automotive and aviation, which utilize electrical connectors, wire, cable and other electrical parts and supplies; industrial manufacturing, for use in machinery requiring electric transformers, power supplies and electrical switches; medical, that utilizes devices such as implantable sensors and low current amplifiers. Electrical components are formed from a variety of different conductive materials including copper, silver and aluminum.

Types of Electrical Components:

Electric Coils

Electric Coils come in a variety of configurations and these items are typically designed from conductive metals such as copper and aluminum. These coils are used for transferring heat, sound or electricity and manufacturers can customize the electric coils to meet the specific requirements of an application. Electric coil types range from choke coils, encapsulated coils, high voltage coils, ignition coils, impregnated coils, induction, magnetic coils, molded coils, solenoid coils, tape wrapped coils, toroidal coils, transformer coils and various other styles.

Electric Heaters

Electric heaters are devices that use electrical energy to create heat. Heat is a very important part of many manufacturing processes and many electric heaters can be designed to provide controlled localized heat. Air heaters are typically installed with a fan system to offer heat in a large setting while cartridge heaters are incorporated into machinery to heat a smaller area. Immersion heaters are specialized heaters that can be immersed into liquids and solids and still properly function.

Electric Transformers

These items are used for transferring electrical energy between multiple circuits by means of a process called electromagnetic induction. The energy is sent out from a source such as a power plant where the energy is transformed into a high voltage state for transportation and when the electricity reaches another transformer the energy is transformed or “stepped down” into a more usable state. Most electric transformers are isolation transformers due to the fact they transmit electricity through induction.

EMI Shielding

EMI shielding is a term used for product that protects electronic equipment from electromagnetic interference. EMI protection encompasses many products such as filters, gaskets, enclosures and coatings. The term RFI shielding refers to the electromagnetic “noise” that travels through radio waves and RF absorbers are radar absorbers that absorb magnetic energy from RFI waves before the interface reaches equipment. EMF shielding refers to shielding that protects equipment from electromagnetic fields.
