三、Application & attention
Quartz crystal oscillator (referred to as crystal oscillator) is often used in smart furniture, Bluetooth products, car audio, computer host board, DVD/VCD player, MP4, MP3 player and other smart electrical products with single-chip microcomputer. When used, the welding temperature should not be too high, and the time should not be too long. If reflow welding is used, reference temperature is recommended, and wave crest welding is not recommended. Products should be stored in the ambient temperature of -10℃~40℃, relative humidity is not more than 80%, the surrounding environment is not acidic, alkaline and other harmful gases in the warehouse. Do not soak when cleaning, it is recommended to wipe with alcohol.
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.
