■ Handling Notes

Mounting

Bending Lead

Soldering the body of cylinder type crystal unit must

be strictly avoided as it may cause significant

deterioration in characteristics of the product.

Hold the body of crystal unit by hand, and the part to be

bent with tweezers leaving more than 1.5mm of lead from

the body case. (3.0mm is recommended)

Rubber adhesive is recommended for mounting.

Bend the lead 90°holding with the tweezers. Pulling the

lead strongly may crack the hermetic seal glass at the root

of the lead and may cause the airtightness and the

characteristics to deteriorate.

Product specifications are subject to change without notice.
