7M-27.120MBGJ-T application field and working principle

Crystals are a type of solid material which consists of an atomic structure that is regularly repeating in three dimensions. They can be composed of molecules, ions, or atoms. 7M-27.120MBGJ-T is a crystal resonator, also known as a quartz crystal, commonly used in electronic frequency control applications. It is made of crystalline quartz, an inorganic material with a definite frequency response. It works on the principles of vibrating quartz oscillators to produce an electrical signal at a specific frequency.

Application Field

7M-27.120MBGJ-T is widely used in the area of frequency control. It is ideal for any electronic device that needs to generate a precise and accurate frequency. The crystal is used for many products such as processors, computers, automotive systems, phones, radios and other communication systems, digital hardware and network devices, navigation systems, and clocks. It is also suitable for digital audio, radio frequency identification applications, and various industrial, robotics and military applications.

Working Principle

The quartz crystal works by the piezoelectric effect which is an electrical charge that is produced when a mechanical stress is applied to the quartz crystal. Application of an electrical field on the crystal can also create mechanical forces that cause it to vibrate at a certain frequency. When this vibration is at a resonant frequency, electrical oscillations are generated.

The 7M-27.120MBGJ-T operates in parallel-resonant mode, meaning that its frequency is determined by the resonance of the two plates of the crystal. It has an operating temperature of - 20°C to +85°C and has a series resistance of 18.0 Kohms and a load capacitance of 12.0pF. It is a very low power device and with a frequency capacity of 1.0922MHz to 27.120MHz.

Conclusion

7M-27.120MBGJ-T is a quartz crystal that is widely used in the area of frequency control. It works on the principle of the piezoelectric effect, where an electrical charge is produced when a mechanical stress is applied to the crystal. It is suitable for various electronic applications that need to generate a precise and accurate frequency, and can operate at temperatures ranging from -20°C to +85°C.
