!Caution/Notice
c !Caution (Storage and Operating Condition)
This product is designed for application in an
ordinary environment (normal room temperature,
humidity and atmospheric pressure). Do not use under
the following conditions because all of these factors
can deteriorate the characteristics or cause product
failure and burn-out.
1. Corrosive gas or deoxidizing gas (Chlorine gas,
Hydrogen sulfide gas, Ammonia gas, Sulfuric acid
gas, Nitric oxide gas, etc.)
2. Volatile or flammable gas
3. Dusty conditions
4. Under vacuum, or under high or low pressure
5. Wet or humid conditions
6. Places with salt water, oils, chemical liquids or
organic solvents
7. Strong vibrations
8. Other places where similar hazardous conditions
exist
c !Caution (Other)
Be sure to provide an appropriate fail-safe function
on your product to prevent secondary damage that may be
caused by the abnormal function or the failure of our
product.
c Notice (Storage and Operating Condition)
To keep solderability of product from declining,
the following storage conditions are recommended.
1. Storage condition:
Temperature -10 to +40 degrees C
Humidity less than 75%RH (not dewing condition)
2. Storage term:
Use this product within 6 months after delivery
by first-in and first-out stocking system.

c Notice (Soldering and Mounting)
PTGL Series
When the lead of this product is soldered, observe
the following points to avoid the decline of element
characteristics or break-down of the element.
1. Use rosin type flux or non-activated flux
2. Do not dip the body into flux (flux should be
coated to lead wire only for soldering).
3. Be sure that preheating does not melt the
soldering of this product.
c Notice (Soldering and Mounting)
PTFL/PTFM Series
1. PTFM Series is to be screwed beside the Power-
Transistor on the radiative plate.
2. If PTFL Series is to be mounted with thermal cement,
the cement should not be of the Cyano Acrylate
family.
3. Please bend the lead wire far from the root of the
body and do not apply force to the lead wire of
the product.
4. When the lead of this product is soldered, observe
the following points to avoid the decline of
element characteristics or break-down of the
element.
(1) Use rosin type flux or non-activated flux.
(2) Do not dip the body into flux.
(Flux should be coated to lead wire only for
soldering.)
(3) Be sure that preheating does not melt the
soldering of this product.
