!Note • Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.
• This catalog has only typical specifications. Therefore, please approve our product specifications or transact the approval sheet for product specifications before ordering.
!Caution/Notice
!Caution
o Rating
Do not use products beyond the rated current and rated voltage as this
may create excessive heat and deteriorate the insulation resistance.
o Soldering and Mounting
1. Mounting holes should be designed as specified in these
specifications. Other designs than those shown in these
specifications may cause cracks in ceramics that may
lead to smoking or firing.
2. DSN9/DST9/DSN9H/DST9H/VFS9V Series
Mounting for PCB. (Applis only to bulk type.)
The form of the mounting hole of the bulk item is a triangle.
The product should be inserted and soldered to each hole in
the correct way as in Fig.1. (The center terminal and the other
terminals become parallel when viewing the product from the
side.) Smoking and firing maybe caused by incorrect mounting
as in Fig.2. (The center terminal and the other terminals cross
when viewing the product from the side.)

3. Take care not to apply any mechanical stress to product
body at the lead terminal bending process for product
angle adjustment after insertion.
For DST9, please do not bend the lead terminal at the
point between the dielectric part and the ferrite bead.
