What is an Electromagnet?

An Electromagnet is a winding with a soft, laminated, or pressed powdered iron core, which generates an extremely strong field of magnetic force when current is passed through the winding.

It may include tuning devices, integral resistors and capacitors; however, excludes FILTER (as modified). The coil has only two electrical terminals. For items having tapped winding or more than one winding - see TRANSFORMER, RADIO FREQUENCY. For coils wound on resistors, which are designed to be inserted in the circuit of a radio frequency stage to suppress high frequency parasitic oscillations, see SUPPRESSOR, PARASITIC.

What is a Saturable Reactor?

A Saturable Reactor is an item whose inductance value is controlled by electrical means. It depends on the action of the electromagnet flux produced by the control winding upon the effective permeability of the core. It contains two or more windings, at least one of which must be a control winding. For items designed to be used in conjunction with a rectifier(s) for amplification purposes, see AMPLIFIER, MAGNETIC.

What is a Discriminator Transformer?

A Discriminator Transformer (TRANSFORMER,DISCRIMINATOR) is a transformer designed to be used in a stage where frequency modulation signals are converted directly to audio frequency signals or in a stage where frequency changes are converted to corresponding voltage changes. May include capacitors, resistors and/or coils as integral parts.

What is an Electrical Coil?

An Electrical Coil (COIL,ELECTRICAL) is an item generally consisting of one or more turns of wire or similar conductive material (in special cases it may be considered as a partial turn). It is specifically designed to concentrate magnetic flux generated by the flow of an electric current, to induce in itself an electromotive force, and to add or subtract inductive reactance in a circuit. It may include tuning devices, integral resistors and capacitors; however, excludes FILTER (as modified). For coils wound on resistors which are designed to be inserted into the circuit of a radio frequency stage to suppress high frequency parasitic oscillations, see SUPPRESSOR, PARASITIC..

What is a Power Transformer?

A Power Transformer (TRANSFORMER,POWER) is a transformer consisting of one or more primary winding(s) and one or more secondary winding(s). It may be designed for direct connection to an alternating current source for purposes of changing the secondary volts and amperes or designed to eliminate metallic interconnection between circuits in an overall one to one voltage ratio, with or without additional output windings, or items designed to automatically maintain a constant output voltage within specified limits under varying input or load conditions. Also includes items having a provision for mechanically changing the turns ratio or inductive coupling in progressive increments by means of voltage taps, ratio adjuster, or devices oe similar design. For transformers having winding(s) common to both input and output circuits, see TRANSFORMER (1), POWER, AUTOTRANSFORMER. Excludes TRANSFORMER (1), PULSE.

What is a Power Autotransformer Transformer?

A Power Autotransformer Transformer (TRANSFORMER,POWER AUTOTRANSFORMER) is a transformer which incorporates the primary and secondary functions into a single winding, which is common to both input and output circuits, and is designed to change the relationship of volts and amperes between the entire winding and its taps. Includes multiple winding transformers of like design and items in which a variation of the turns ratio or inductive ratio of inductive coupling is accomplished by connection to fixed terminals. Also, includes items having a provision for mechanically changing the turns ratio in progressive increments, by means of a shaft, voltage taps, ratio adjuster, or devices of similar design. Excludes TRANSFORMER (1), POWER; TRANSFORMER (1), PULSE.

What is an Electrical Coil Assembly?

An Electrical Coil Assembly (COIL ASSEMBLY,ELECTRICAL) is two or more COIL, ELECTRICAL on a common mounting or mounted on each other. Excludes items inductively coupled. For items inductively coupled, see TRANSFORMER (as modified).

NATO Supply Class 5950 is a classification within NATO Supply Group 59, which is dedicated to Electrical And Electronic Equipment Components.

Specifically, Class 5950 focuses on Coils And Transformers. Coils are devices that consist of a series of windings or turns of wire, typically wound around a core, and are used to create magnetic fields or to store energy. Transformers, on the other hand, are devices that consist of two or more coils of wire that are linked by a magnetic field. They are used to transfer electrical energy between different circuits with different voltage levels.

In the context of NATO supply classification, Class 5950 includes various types of coils and transformers that are used in electrical and electronic equipment. This can include power transformers, audio transformers, inductors, chokes, and other similar devices.

The purpose of this classification is to provide a standardized system for identifying and categorizing coils and transformers used in military and defense-related applications. This allows for easier procurement, inventory management, and logistics support within NATO member countries.

If you need more specific information about a particular type of coil or transformer within Class 5950, please let me know and I'll be happy to assist you further.
