With the rapid development of Smart electronic products in China, wireless Bluetooth headset, wearable smart visual watch and other common electronic products have gradually become the mainstream solutions of today's smart electronic products. These intelligent electronic products need to use crystal vibration on the main board is also more and more, like 2.5 G module in this 2.5 G module motherboard common to a 40 MHZ crystal passive vibration, the 2.5 G module crystals have subminiature encapsulated with the features of high precision for wireless bluetooth module, are very appropriate, choose a suitable 2.5 G module crystal vibration of its frequency precision, stability and volume demand is higher, so based on the demand of branch crystal electron recommend a commonly used in the 2.5 G module Q24FA20H0009700 epson crystal vibration.

The crystal vibration of Q24FA20H0009700 has passed ISO14001 international environmental standard certification, and the working temperature has the industrial grade temperature of -40~85℃, so that the product can still work normally in the harsh environment of hot and cold electronic products. The frequency tolerance (standard) of FA-20H is ±30x10-6. Therefore, in the application of 2.5g module, high output frequency accuracy can be guaranteed, so as to output more accurate signals. In addition, in terms of power consumption, the maximum excitation power of FA-20H is 200 W, which is enough to meet the requirements of low power consumption of 2.5G module.
Epson Q24FA20H0009700 crystal vibration model of load capacitance pf 10, 10 PPM precision, high stability, is suitable for sensitive to design area of intelligent equipment design, FA - 20 h crystals its small size, high precision, low power consumption characteristics and excellent heat resistance and resistance to environmental characteristics, be the best choice of intelligent equipment clock dressing, moreover FA - 20 h crystals metal shell encapsulation makes products in packaging can play better than ceramic resonator shell resistance to impact, greatly improving the intelligent wear equipment environment adaptability and resistance to fall off.
