Precautions for Use
[Airtightness] This product is not structured to provide a complete air seal. Therefore it cannot be immersed in solutions for
purposes such as boiling tests or ultrasonic cleaning.
[Ability to withstand soldering heat]
The package of this product contains thermoplastic resin which has a limited ability to withstand heat. Therefore
this product cannot be put through automated soldering operations in which the ambient temperature exceeds
the specified temperature. The recommended soldering conditions are as follows.
· Temperature of soldering iron tip : 260C or less
]
or
· Soldering time
: 5 seconds or less
· Soldering position
: At least 2 mm away from lead base
[Ability to withstand chemicals]
If the transparent case requires cleaning, wipe it lightly using ethyl alcohol, methyl alcohol, or isopropyl alcohol.
If you plan to use other solvents, carefully check to make sure there are no problems such as a misshapen case or
a change in the condition of the case material.
: 300C or less
: 1 second or less
