Use this component within operating temperature range. It might not be satisfied with electrical specification without operating temperature range. When it is used less than -10ºC or more than +60ºC, it might be a cause of degradation or destruction of the component. Even if it endures during a short time, it causes degradation of qualification. When soldering iron is used, solder with the temperature at the tip of soldering iron: 350ºC max. , the time of soldering: 10 seconds max. , the power of soldering iron: 30W max. . Notice that the allowed time of soldering with soldering iron is accumulated time, when soldering is repeated. As rapid temperature change for cleaning after reflow soldering might be a cause of destruction clean this component after confirming that temperature of this component goes down to room temperature. Confirm that there are not any influence for qualification to this component in mounting on PCB when this component is cleaned. As it might be a cause of degradation of destruction to apply static electricity to this component, do not apply static electricity or excessive voltage while assembling and measuring. And do not transport this component with bare hand. As it might be a cause of degradation or destruction to apply D. C. voltage between each terminal, apply D. C.
