Crystals

A 402F37412IAR is a highly advanced crystal used for many applications. It is an integrated quartz crystal resonator, which uses its own frequency stability to control the operation of the device

A 402F37412IAR crystal is made from quartz and can reach frequencies up to 50 MHz. The crystal is packaged in a three-lead surface mount package, which is typically used in communication devices. The crystal is designed to be used as an oscillator or frequency reference in electronic circuits, and it has excellent temperature stability, low phase noise and low power consumption, making it one of the most reliable and cost-effective crystals available.

The 402F37412IAR crystal is most commonly used in radio communication circuits where it acts as a frequency reference, providing the precise and stable frequency needed for the operation of the device. Some typical applications include GPS receivers, radio frequency transceivers, and base stations. The crystal is also used in many consumer electronics applications such as televisions, DVD players, and alarm systems.

The typical operating principle of the 402F37412IAR crystal is based on the mechanical resonance of the quartz crystal. When an electrical signal is applied to the crystal, it begins to vibrate. This vibration, together with a small capacitance within the crystal, forms an oscillating electrical circuit, producing a specific frequency output. The crystal\'s built-in frequency stability ensures that this frequency stays within a small tolerance over a wide range of temperatures and other factors, providing a very accurate and reliable frequency reference.

In addition to its use as a frequency reference, the 402F37412IAR crystal can also be used as a timing generator in microcontroller-based systems. This is achieved by using a frequency-controlled oscillator to measure the length of microcontroller instructions and providing a stable clock signal to the microcontroller. In this way, the crystal can be used to ensure that the microcontroller always runs at the correct speed and with the accuracy required.

The 402F37412IAR crystal is a versatile and reliable quartz crystal resonator, used in a variety of applications. Its excellent frequency stability, low phase noise and power consumption make it an ideal choice for many communication and consumer electronics devices.
