Recommended Land Patterns
Circuit design
1) Once application and assembly environments have been checked,
the resistors may be used in conformance with the catalog and the
specifications.
2) Please consult the manufacturer in advance when the resistors is
used in devices such as: devices which deal with human life, i.e.
medical devices; devices which are highy public orientated; and
devices which demand a high standerd of liability.
3) Please use the resistors in conformance with the operating
temperature provided in both the catalog and the specifications.
4) Please keep voltage under the rated voltage which is applied to the
resistor.
5) Do not use the resistor in an environment where it might easily
exceed the respective provisions concerning shock and vibration
specified in the catalog and specifications.
6) Please do not use the resistor in the following environments.
①
State that water, oil, and solvent hang in resistor
②
State where poisonous gas (sulfur and chlorine, etc.) exists
③
State that direct sunshine, radiation, and ultraviolet, etc. are irradiated
7) There is a thing that resistance changes according to the stuff of
the resin when the coating with the resin is given.
Please use resin coating after confirming the characteristic.
8) There is a thing that resistance changes according to flux and
cleaner.
Please use flux and cleaner after confirming the characteristic.
9) Please consult about a lead free products.
Storage
1) Keep storage place temperature +5 to +35°C, humidity 45 to 75%
RH.
2) Please keep parts out of poisonous gas such as sulfur or chlorine
in the air and out of salty moisture, or they may cause rust of
terminal and poor solderability. Please consider the above-
mentioned item after mounting.
3) Soldering iron
Temperature soldering iron 300±5°C *
Time 3 sec. max. *
*Do not place the soldering iron on the chip. Soldering iron is 30W max.
