五、Application & attention
M49SMD chip crystal oscillator is widely used in communication products, Bluetooth devices, automotive electronics, smart watches, medical devices, smart furniture, Bluetooth products, car audio, computer host board, DVD/VCD player, MP4, MP3 player and other intelligent electrical products matching with single chip computer.
The company sells chip crystal oscillator, pin crystal oscillator, and user's index requirements to customize the crystal oscillator. Customized vibration requires the user to put forward clear index requirements, and the need for multiple on-board testing, the parameter requirements beyond the physical limit of the material can be negotiated by both sides to achieve the best index.
