HCX-3SB(16MHz) SMD Quartz Crystal Resonator 4. PACKING 1. 230mm minimum leafer which consist of carrier and tape followed by a minimum of 160mm of empty carrier tape sealed with cover tape. 2．160mm minimum trailer of empty carrier tape sealed with cover tape. SHENZHEN LUGUANG ELECTRONIC TECHNOLOGY CO.,LTD. HCX-3SB(16MHz) SMD Quartz Crystal Resonator 5. Note 1. Only the lead should be heated when soldering. In case that the package temperature is exceeding 150°C , it may impair the crystal or may cause the crystal quartz to destroy. 2. Pulling the lead strongly may cause cracking of the hermetic grass seal bending the lead closely from the case may also cause same problem, so when the lead needs to be bent, please leave move than 05.mm of lead from the case. 3. Too much shock or vibration is not allowed. According to conditions such as machine shock during the assembly, the internal quartz crystal might be damaged. Please check your conditions carefully when using it in advance. 4. Don't storage or use in the environment that temperature may change rapidly to avoid the condensation. And also we recommend to storage the products in the normal environment. (Temperature, humidity) 5. This product can be subjected to ultrasonic cleaning. However, since the oscillator may be affected depending on the condition, be sure to check it. 6. Applying excessive drive level to the quartz crystal may cause deterioration for characteristics or damage. Circuit design must be such as to maintain a proper drive level. 7. Unless adequate negative resistance is allocated in the oscillation circuit, startup time of oscillation may be increased or no oscillation may occur. In order to avoid this, provide enough negative resistance in the circuitry design. SHENZHEN LUGUANG ELECTRONIC TECHNOLOGY CO.,LTD.
