Crystals are small pieces of quartz, silica, and other materials that oscillate at very high frequencies. They are used to produce electrical signals with very precise frequency and relative timing. CM309E8000000BCKT is one of the most popular types of crystals used in many applications today. This crystal was developed by Citizen Electronics specifically for consumer use, such as in cell phones, tablets, and other consumer electronics.

CM309E8000000BCKT has a frequency range of 8.00000000Hz. This is produced by using the fundamental-mode crystal frequency which is measured in megahertz (MHz). The crystal is composed of an AT-cut quartz crystal that is encased in a protective coating and housed in a small package. It has a total of eight terminals that are used to interact with the electronics for supplying power, sensing the crystal frequency, and outputting the signals.

CM309E8000000BCKT application field covers a wide range, mostly used in consumer electronics including, but not limited to, cell phones, tablets, GPS, LED lights, electric router controllers, and more. As an electric component, it is used to provide precision timing and generate high frequency clock signals, which are essential to the functionality of these products. This filter operates at its highest potential when it is used alongside specific circuits that are tailored to its use.

CM309E8000000BCKT can operate in both fundamental-mode and overtone-mode depending on its circuit configuration. The fundamental-mode is where the crystal is coupled with a load capacitance and operates in series resonance with an input signal. This creates an output frequency that is twice the fundamental frequency. The overtone-mode is when the crystal is operated in parallel resonance with an input signal, and the output frequency will be three to nine times the fundamental frequency.

CM309E8000000BCKT typically has about 80kHz pull range, which is mainly determined by the volume of the quartz and the mechanical structure of the quartz. The increased pull range translates to better frequency accuracy because it allows for greater user tuning options when the end application requires precise frequency operation. This crystal can handle a temperature range of -10°C to 70°C and has a strong tolerance to shock and vibration.

In summary, CM309E8000000BCKT is a versatile application crystal with a frequency of 8MHz, a pull range of 80kHz, and a temperature range of -10°C to 70°C. It is used extensively in many consumer applications. It has both fundamental-mode and overtone-mode for different application requirements. It is also very tolerant to shock and vibration, making it highly reliable for industrial and medical applications.
