5. note 1. only the lead should be heated when soldering. in case that the package temperature is exc eeding 150c , 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 care fully 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 stor age 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 conditi on, be sure to check it. 6. applying excessive drive level to the quartz cr ystal may cause deteriora tion for characteristics or damage. circuit design must be such as to maintain a proper drive level. 7. unless adequate negative re sistance is allocated in the osc illation circuit, startup time of smd 7.0x5.0 smd quartz crystal resonator
oscillation may be increased or no oscillation may occur. in order to avoid this, provide enough negative resistance in th e circuitry design. smd 7.0x5.0 smd quartz crystal resonator
