Crystals

Crystals have long been used in electronics and technology to serve as an active or passive component for a variety of applications. The crystal is typically made of an single element or a combination of elements and compounds that are arranged in an orderly pattern, much like a 3-D lattice. The crystal\'s lattice structure has the unique ability to convert mechanical or electrical energy into an oscillating electrical signal at a specific frequency. A type of crystal called a 402F40011CAT is commonly used in many electronic applications because of its high frequency stability, precision and wide range of operating temperature.

402F40011CAT Application Field

The 402F40011CAT is a miniature surface-mount ceramic resonator that is typically found in equipment such as communications infrastructure, sensors, meters, automotive and military data link systems, and a variety of other electronics. It is designed to operate reliably over an extended temperature range of -45 °C to +125 °C and delivers a frequency stability of +/-15 ppm. It has superior frequency stability compared to quartz crystals and also provides fast frequency switching. The crystal\'s small size and low power consumption make it well suited for space-constrained applications.

402F40011CAT Working Principle

The 402F40011CAT works on the same principle as any other crystal-based oscillator. The crystal is made up of two plates of metal, one connected to its electrode and the other connected to the ground. At regular intervals, the plates vibrate because of the electric field created between them. As the crystal vibrates, it produces an oscillation of electric current. This oscillation is used to produce an accurately timed continuous signal. This oscillation is then amplified and sent to a receiver, which can interpret the signal.

The 402F40011CAT is designed to oscillate at a very high frequency and offer greater stability than other crystal oscillators. This is accomplished by using a low static capacitance and higher quality factors. The use of higher quality factors slows down the oscillations, resulting in more stable frequencies. The crystal also uses additional precautions to minimize the influence of environmental factors, such as temperature, moisture, and strain, on the crystal oscillation.

Conclusion

The 402F40011CAT crystal is used in a wide variety of applications, from automotive systems to military data links. It is designed to provide superior frequency stability and fast frequency switching in a small, low-power package. The crystal works by allowing an electric field to oscillate plates of metal, creating an electrical signal. This signal can then be amplified and sent to a receiver for interpretation.
