Caution

Dont apply excess mechanical stress to the component and terminals at soldering. Do not use this product with bend.
Do not clean or wash the component for it is not hermetically sealed.
Do not use strong acidity flux, more than 0.2wt% chlorine content, in flow soldering.
This specification mentions the quality of the component as a single unit. Please ensure the component is thoroughly evaluated in your application circuit.
Expire date (Shelf life) of the products is six months after delivery under the conditions of a sealed and an unopened package. Please use the products within six months after delivery. If you store the products for a long time (more than six months), use carefully because the products may be degraded in the solderability or rusty. Please confirm solderability and characteristics for the products regularly.
