■ 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.
