FA-238 19.2000MB-C3

Crystals are important and versatile components of electronic systems. FA-238 19.2000MB-C3 is a popular crystal among the manufacturers of consumer electronics. It is a surface mount quartz crystal that is used in many consumer-oriented applications. The following will discuss the application field and working principle of FA-238 19.2000MB-C3.

Application field

FA-238 19.2000MB-C3 is mainly used in consumer electronics such as portable communication devices, MP3 players and multimedia players. It is also used in some medical devices, point-of-sale (POS) systems and other electronic devices. As a surface mount quartz crystal, its size is much smaller than conventional through-hole crystals, so it can be easily integrated into the circuit board.

Working Principle

FA-238 19.2000MB-C3 operates on the piezoelectric effect. A quartz crystal consists of two electrodes and a piezoelectric material sandwiched between them. When voltage is applied to the crystal, it causes its internal stress level to change, which in turn changes its frequency. When the voltage is removed, the crystal reverts back to its original frequency.

The frequency of the FA-238 19.2000MB-C3 crystal is 19.2000MHz. This frequency is determined by the size of the quartz crystal and the type of piezoelectric material used. Because of the crystal\'s small size and precise resonant frequency, it is used in precise timing and frequency applications such as wireless communication and embedded systems.

The accuracy of the FA-238 19.2000MB-C3 crystal is determined by two factors: the temperature stability of the crystal and the pullability. Temperature stability is the ability of the crystal to stay at its resonant frequency despite changes in temperature while pullability is the ability of the crystal to remain at its original frequency regardless of changes in the applied voltage.

Additionally, the FA-238 19.2000MB-C3 crystal has an impedance matching feature. This feature helps to minimize any losses due to impedance mismatches between the crystal and the circuit board. This feature ensures that the crystal will produce a consistent and accurate frequency even if there are differences in impedance between the crystal and the circuit board.

In conclusion, the FA-238 19.2000MB-C3 crystal is an important component in many applications due to its small size, precise resonant frequency, temperature stability and pullability. It also has an impedance matching feature which helps to minimize losses due to impedance mismatches. This makes it an ideal component for applications that require precise timing and frequency.
