Crystals

Crystals are a class of materials with unique properties that make them desirable for various applications. Their highly ordered atomic arrangement leads to their property of possessing a well-defined electrical conductivity. This conductivity is the basis for their use in digital circuits, communication devices and sensor applications. The most commonly used crystal of today is the 9C12000136. The 9C12000136 is a small quartz oscillator with a frequency of 14.7456 MHz. It consists of a 9.8 mm by 12.8 mm quartz crystal enclosed in a SMT metal can. It is characterized by its wide frequency operating temperature range of -20 °C to +85 °C. It also has excellent frequency stability over a wide frequency range and temperature range. The working principle of the 9C12000136 crystal involves the application of an external voltage to the electrodes of the crystal which generate a change in the internal electric field of the crystal lattice. As a result, mechanical stress is generated which deforms the crystal. This deformation of the crystal lattice results in the crystal vibrating at a frequency equal to its fundamental resonance frequency. The oscillation of the crystal is maintained by passing the generated pulses through an external circuit which amplifies the signal generated. The 9C12000136 crystal is used in a wide variety of applications such as radio receivers, timing circuits, frequency-controlled oscillators, switching power supplies and embedded systems. The crystal is used in radio receivers in order to generate signals of the required frequency. It is also used in timing circuits in order to accurately measure time. The crystal is used in frequency-controlled oscillators to accurately generate oscillation frequencies. In switching power supplies, the crystal is used to provide stable voltage to the circuit. Finally, it is also used in embedded systems such as computers and calculators in order to accurately and quickly process data signals. The 9C12000136 crystal has numerous advantages over other types of oscillators, most notably its wide operating temperature range and high frequency stability. Its size and weight also make it an attractive choice for embedded systems, and its relatively low cost makes it attractive for use in mass produced consumer electronics. Finally, it is also extremely reliable and has a long service life. The 9C12000136 crystal is an incredibly versatile and reliable component which provides an excellent basis for various electronic systems. Its wide frequency operating temperature range and high frequency stability make it an ideal choice for numerous applications. Furthermore, its small size and weight make it attractive for embedded systems, while its relatively low cost makes it attractive for use in mass produced consumer electronics.
