The 7B-27.120MBBK-T is a popular crystal used in wireless communication applications. It is a quartz crystal with a frequency of 27.120 MHz, which is within the 2.4 GHz ISM band or in other words the 2.4GHz wireless communication band. This crystal, when used as an oscillator, is suitable for building wireless networks, Bluetooth, Zigbee and Wi-Fi applications.

The 7B-27.120MBBK-T can be used in a variety of electronic components such as oscillators, timers and frequency counters. Typically it is used as a resonator in an oscillator circuit. As an oscillator, it is usually used in conjunction with a transistor or IC as a driver circuit. The crystal works as an element in the oscillator which provides a very precise frequency and allows very precise oscillation.

Working Principle

The 7B-27.120MBBK-T crystal works on the principle of vibration. A quartz crystal has a property of piezoelectricity, which means that when an electrical charge is applied to it, it creates mechanical vibrations in the crystal. These vibrations occur at the crystal\'s natural resonance frequency and can be used to create a very precise oscillation.

When the 7B-27.120MBBK-T crystal is used as an oscillator, it is typically connected to a transistor or IC. The electrical signal from the transistor or IC drives the crystal, causing it to vibrate and create an oscillation at the crystal\'s resonance frequency. This oscillation can then be used to drive other components, such as a frequency counter, or can be used as a signal source for transmission or reception purposes.
