Using these 16MHz crystal SMDs is quite straightforward. First, check if your device is suitable for this type of crystal, especially if it uses the nRF2401 ICs. When installing, make sure to handle them gently due to their small size. Place them on the designated area on your circuit board according to the layout. Regarding the operating temperature, keep your device in an environment between -20°C and +70°C to ensure stable performance. As for maintenance, try to keep them clean and free from dust. If you need detailed technical information, refer to the datasheet.
