What is a Quartz Crystal Unit?

A Quartz Crystal Unit (CRYSTAL UNIT,QUARTZ) is an item which consists of a quartz crystal resonator(s), suitably mounted in a HOLDER, QUARTZ CRYSTAL.

What is a Crystal Holder Retainer?

A Crystal Holder Retainer (RETAINER,CRYSTAL HOLDER) is an item of unusual or unique construction specifically designed to restrain the movement of a HOLDER (1), CRYSTAL UNIT when mounted in another item.

What is a Crystal Unit Holder?

A Crystal Unit Holder (HOLDER,CRYSTAL UNIT) is a holder designed to be used with a crystal unit. For those items which contain provisions for gripping terminals, see SOCKET (as modified). See also HOLDER, SEMICONDUCTOR DEVICE.

What is a Crystal Controlled Oscillator?

A Crystal Controlled Oscillator (OSCILLATOR,CRYSTAL CONTROLLED) is an oscillator whose operating frequency(ies) is controlled by a CRYSTAL UNIT, QUARTZ. For an oscillator controlled by a device other than a crystal, see OSCILLATOR (1), NONCRYSTAL CONTROLLED. See also GENERATOR, SIGNAL; and CALIBRATOR, FREQUENCY. Excludes FREQUENCY SUPPLY, TELEPHONE CARRIER; RESONATOR, TUNING FORK; and OSCILLATOR, PULSE DELAY.

What is a Noncrystal Controlled Oscillator?

A Noncrystal Controlled Oscillator (OSCILLATOR,NONCRYSTAL CONTROLLED) is an oscillator whose operating frequency(ies) is controlled by an electronic device other than a CRYSTAL UNIT, QUARTZ. For an oscillator controlled by a crystal, see OSCILLATOR (1), CRYSTAL CONTROLLED. See also GENERATOR, SIGNAL; and CALIBRATOR, FREQUENCY. Excludes FREQUENCY SUPPLY, TELEPHONE CARRIER; RESONATOR, TUNING FORK; and OSCILLATOR, PULSE DELAY.

What is an Electrical-Electronic Components Oven?

An Electrical-Electronic Components Oven (OVEN,ELECTRICAL-ELECTRONIC COMPONENTS) is an electrically heated compartment designed to accommodate and maintain at an essentially constant temperature, one or more components, such as, CRYSTAL UNIT(S), QUARTZ; tuned circuits; integrated circuit devices; and semiconductors. It prevents frequency drift and changes in teperature.

NATO Supply Class 5955 is a classification within NATO Supply Group 59, which is dedicated to Electrical And Electronic Equipment Components.

Specifically, NATO Supply Class 5955 focuses on Oscillators And Piezoelectric Crystals.

Oscillators are electronic devices that generate repetitive electronic signals, typically in the form of a sine wave or a square wave. They are used in various applications such as communication systems, timing circuits, and frequency synthesis.

Piezoelectric crystals, on the other hand, are materials that generate an electric charge when subjected to mechanical stress or pressure. They are commonly used in electronic devices for their ability to convert mechanical energy into electrical energy and vice versa. Piezoelectric crystals find applications in sensors, transducers, and actuators.

In summary, NATO Supply Class 5955 encompasses the procurement and classification of oscillators and piezoelectric crystals, which are essential components in electrical and electronic equipment.
