Remarks on Usage
A) Storage Condition
Parts should be stored in temperature range of −5 to +40°C, humidity 40 to 60% RH, and avoid direct sunlight. Then use within 6 months.
B) Handling Condition
Although oscillators have protection circuit against static electricity, the inside IC may be damaged. when excess static electricity is applied,
When mounting on PCB, make sure the direction of oscillators are correct, otherwise oscillators will increase in temperature and may be
damaged.
Please do not use oscillators under unfavorable condition such as beyond specified range in catalog or specification sheet.
Please keep oscillators away from water, salt water or harmful gas.
K50H-3C/K50S-3P series should be stored in humidity-controlled area after the package is unsealed
, in temperature +25 ±5°C, under
humidity of 65%RH, and should be mounted on PCB within 7 days.
C) Soldering
Use oscillators only with IR reflow for soldering.
D) Washing Condition
Ultrasonic cleaning is available. However there is a possibility that crystal in oscillator may be damaged under certain condition. Therefore
please test before use.
After washing, please dry oscillators completely. Otherwise water drops between oscillators and PCB may cause electro-migration.
