Crystals: 402F2001XIJT Application Field and Working Principle

The 402F2001XIJT crystal is an inductively-loaded crystal appropriate for low-power embedded and IoT applications. This crystal family consists of a variety of shapes, sizes and capacitance levels that make it adjustable to match specific application requirements. Used in combination with an appropriate oscillator circuit, the 402F2001XIJT crystal can serve as a low-power, low-profile frequency reference in many types of wireless applications.

Crystals are the cornerstone of frequency control and accuracy. Frequency is the measure of how often something occurs and it is expressed in hertz (Hz). Scientists discovered that quartz crystals show frequency stability when exposed to specific electrical stimuli and since then they\'ve been used as frequency references in oscillator circuits. This has enabled engineers to implement frequency-targeted applications such as radios, computers and time-measurement tools.

The 402F2001XIJT crystal consists of a quartz crystal element mounted inside a casing, connected electrically to an oscillator circuit. When an appropriate voltage is applied to the crystal element, it starts to vibrate and the frequency of its vibration dictates the frequency of the oscillator circuit. The frequency is determined by the shape and size of the crystal, as well as its coefficient of stiffness, which is the stiffness of the crystal material.

The 402F2001XIJT crystal is designed for use as a low-power, low-profile frequency reference in many types of wireless applications. It is appropriate for use in embedded systems and IoT applications due to its low-power operation, small form factor and low profile. With its adjustable capacitance levels, it can produce frequencies as low as 10kHz and up to 30MHz, making it versatile for a variety of applications.

In addition to its frequency stability, the 402F2001XIJT crystal offers some other benefits, such as low aging, low temperature coefficients and a wide tolerable temperature range. It also meets the FCC specifications for RF application and meets IEC-61000-3-2 conducted emission specifications.

The 402F2001XIJT crystal is an example of how quartz crystals are used as frequency references in oscillator circuits to enable accurate frequency control and to implement frequency-targeted applications. This type of crystal is suitable for use in low-power embedded and IoT applications and its adjustable capacitance range makes it versatile for a variety of applications.
